Lateral Force Resistant Capacity of Light Gauge Steel Modular Building System with Sheathing Panels
Ha, Tae-Hyu ; Lee, Ji-Hyung ; Hong, Sung-Gul ;
Journal of the Architectural Institute of Korea Structure & Construction, volume 29, issue 9, 2013, Pages 3~12
This study aims to estimate the lateral force resisting capacities of multi-story steel stud panel modular buildings. The lateral displacement of modular buildings composed of the rotation and slip deformation of joint and the shear deformation of stud-walls. The shear deformation of steel-stud walls with sheathing panels can be defined by combining several failure mechanisms according to the material properties of sheathing panels and connection detail. This study proposed the theoretical estimation of lateral force resisting capacities according to these procedures. In addition, a two-story modular structure made of steel stud-walls was tested under cyclic loading. The test result shows that the behavior of first story wall is governed by shear diaphragm action explained by equivalent bracing model. Finally this study suggests that lateral resistant behavior of multi story modular system can be explained by rigid body motion as well as shear diaphragm action, which is a characteristic behavior of modular building system caused by bolt connection between lower and upper unit modules.
Nonlinear Analysis of FRP Jacketed Concrete Beams by Mixed Finite Elements
Cho, Chang-Geun ;
Journal of the Architectural Institute of Korea Structure & Construction, volume 29, issue 9, 2013, Pages 13~20
This research presents a nonlinear mixed frame fiber finite element formulation of FRP confined concrete members. Since the mixed finite element formulation don't use the displacement shape functions, the formulation in nonlinear problem can satisfy the equilibrium not only in the section and element levels but also in the structural level. Concrete in compression is modeled as an inelastic material in triaxial stress state in order to predict confining effect of concrete. The FRP sheet is modeled as a layered composite material in two-dimension. A series of four-point bending test of CFRP sheet and concrete composite beams with circular sections is analyzed by the current mixed finite element model. Compared with the test results, it was shown that the model could give well predicted load-deflection responses in the structural level as well as axial and hoop strains in section levels.

A damper system with Kogome truss structure which is known to have higher resistance to plastic buckling and lower anisotropy than other truss periodic cellular metal is introduced and its mechanical properties are covered through theoretical analysis and experimental tests. The effects of design variables such as the thickness of wire, geometric shape of the damper on the shear strength, Young's modulus is theoretically estimated and verified experimentally. By integrating the experimental results, analytic models of damper are provided. In addition, hysteresis loop of the damper under cyclic shear loading is experimentally performed to investigate the energy dissipation capacity and the performance deterioration by the fatigue. Using the hysteresis properties from the experimental tests, the mathematical models of Kagome damper can be predicted from analytical Kagome truss structure ideally assumed to be hinged connected and with no curvature of wire. In order to verify the effectiveness and applicability of the mathematical models, numerical analysis was performed for the 5-story pilotis-structure. From the numerical study, it is found that the mathematical model with smaller yielding strain has an enough energy dissipation effect to reduce the displacement and base shear force of the structure. It is also shown that the mathematical model modified with Young' modulus ratio, yielding stress ratio from theoretic model can be used to predict the hysteresis loop of Kogome damper and the improvement of seismic performance.

Kim, Tae-Soo ;
Journal of the Architectural Institute of Korea Structure & Construction, volume 29, issue 9, 2013, Pages 31~38
Generally, stainless steels have excellent corrosion resistance and durability and among them, austenitic stainless steel (STS304) has been utilized widely in building. Until now, many researches on the application of stainless steels as structural steels have been performed thanks to the global need for sustainability in structures for the reduction of green house gas emission. In this paper, ultimate behaviors such as ultimate strength and fracture mechanism of filles welded connections between stainless steel structural members have been investigated through monotonous tensile test results for welded connections. Specimens are fabricated with the number of welding, weld length and welding direction as main variables. In addition, ultimate strengths by test were compared with those predicted by current design standards; ASCE for cold-formed stainless steel structural members and KBC2009 for hot-rolled steel. Therefore, improved approach for estimating the ultimate strength of fillet welded connections is suggested.

Journal of the Architectural Institute of Korea Structure & Construction, volume 29, issue 9, 2013, Pages 39~46
BIM technologies in fields of architecture have reduced the loss of information, saved time and increased the efficiency of the practice than conventional 2D drawing based works. These technologies are being applied mainly to architectural planning and design, construction, collisions of architectural subsystems, estimation, etc. But few researches to manage structural analysis information for structural engineering were done, even though a lot of efforts to utilize this IFC File has done in other architectural fields. This paper present some ways to design a database for managing information after analyzing structural design stages and referencing the IFC schema, and to construct a initial database from reading an existing IFC file. To implement these ideas, a computer program which can read in the IFC file and manage the structural information on database and then, display all kinds of information with visualization tools is developed. This database approach will give possibilities to share building information and collaborate between various fields of building engineering.

Shin, Hyun-Oh ; Lee, Seung-Hoon ; Lee, Woo-Jin ; Yoon, Young-Soo ;
Journal of the Architectural Institute of Korea Structure & Construction, volume 29, issue 9, 2013, Pages 47~55
This paper presents an experimental study of the mechanical properties such as compressive strength, splitting-tensile strength, flexural strength, modulus of elasticity, and poisson's ratio of 200MPa ultra-high-strength concrete. Effects of primary variables such as fine aggregate type and curing age were studied in this research program. Silica sand, electric arc furnace oxidizing slag, and washed sand were used in the concrete as fine aggregate. For each fine aggregate type, mechanical properties were evaluated at age of 3, 7, 14, 28, 56, and 91 days. The mechanical properties of ultra-high-strength concrete specimens were characterized by extremely brittle and explosive behavior without notable micro-crack or advance warning before failure. Test results indicated that using silica sand as fine aggregate are effective in long term mechanical properties of ultra-high-strength concrete. A comparative study of existing prediction equations for mechanical properties of concrete was also conducted to asses their capabilities of predicting the mechanical properties of ultra-high-strength concrete. To this end, test results in the present study were compared with currents code equations.

Han, Min-Cheol ; Woo, Dae-Hun ;
Journal of the Architectural Institute of Korea Structure & Construction, volume 29, issue 9, 2013, Pages 57~64
This paper is to investigate experimentally the effect of the use of waste refined cooking oil(ERCO) on the engineering properties of the high volume admixture concrete. Fly ash and blast furnace slag were replaced by cement by as much as 30% and 60%, respectively. Fresh properties, strength development, accelerated carbonation and porosity by mercury intrusion penetration methods were tested under various dosages of ERCO. It showed that an increase of ERCO resulted in reduction of slump and air contents, and compressive strength also showed declining tendency. Test results also indicated that the incorporation of ERCO led to enhance the carbonation resistance of the high volume admixture concrete due to saponification reaction between fat acid in ERCO and
. Based on MIP observation, the use of ERCO can fill the capillary pore, which contributes to reduce the amount of total pore volume.

Ultra high-performance concrete which has recently been studied was developed to complement the brittle behaviour and dynamic uppermost limit of high strength concrete. Fiber reinforced concrete which mixed steel fiber is receiving attention as an alternative about this and is being developed to complement the disadvantages of high strength concrete including lower toughness coefficients and crack resistance and spalling in fires. Review about fiber reinforced ultra high-strength concrete that this study tries to treat includes reduction of autogenous shrinkage generated by high cement content per unit volume of concrete, evaluation of compressive and tensile strength to lower internal and external spalling resistance and fragility factors of member of framework, and flow characteristics of concrete which doesn't harden according to steel fiber amounts and used materials. As the result, the more fiber reinforcement increases, the more compression and tensile strength increase and deformation control of cement matrix and improvement of energy absorption ability showed the great effect in shrinkage reduction.

Miyauchi, Hiroyuki ; Lee, Jun ;
Journal of the Architectural Institute of Korea Structure & Construction, volume 29, issue 9, 2013, Pages 73~80
For the purpose of improving water-tightness and durability of sealed joint, the cross-sectional shape of sealed joints to reduce the stress-concentration at the adhesive part of substrate were proposed, and their fatigue resistance was evaluated by fatigue testing machine. The parameters of test specimen were the cross-sectional shapes and the adhesion types of sealed joints. Also, before carrying out the tensile test and the joint movement cyclic test, the stress condition into the cross section of sealed joint was analyzed by finite element method. As a FEM results, the maximum principal compression of rectangle joint was higher than concave joints. Also, in tensile and fatigue test results, when occurring adhesion loss on the substrate, the fatigue resistance of sealed joint decreased extremely. However, when there is adhesion loss on the substrate, the sealed joint with concave cross-section had higher fatigue resistance than that of rectangle shape.

Ji, Suk-Won ;
Journal of the Architectural Institute of Korea Structure & Construction, volume 29, issue 9, 2013, Pages 81~88
This study intends to propose a method to take pictures of concrete surface using a recently popularized digital camera and patternize shade distribution for the deployed histogram through image processing in order to develop a generalized evaluation method evaluate concrete surface work. Through this method, it is determined that it is possible to seek for possibility to utilize it as a comprehensive evaluation criteria for concrete surface finish and suggest a logical approach for concrete quality evaluation. From the results of the study, the following conclusions could be earned : 1) Concrete surface has shown a histogram distribution of a simple structure with easy patternization different from general images. 2) It was possible to earn several patterns through normalization of the histogram on the concrete surface images. I could also see that from results of consistency works on pattern on the actual images, most of images are consistent to the designed patterns. In addition, as individual images showed characterized unique pattern for each type of image, it would be possible to develop a characterized evaluation technique.

Journal of the Architectural Institute of Korea Structure & Construction, volume 29, issue 9, 2013, Pages 89~96
In Korea, the traditional ceramic techniques such as roof tile and traditional brick has been developed. And these have been developed as combining with traditional techniques after manufacturing technology of red brick was introduced from Japan and Western. In this study, the bricks technology is analyzed with the historical analysis to introduction and development, based on the properties of the red brick manufactured in modern Korea. From the result, The clay brick which is used in the early 1900s has even lower property than present clay brick because of propagation of heating facility such as Hoffmann kiln at that time. And, it could be possible to estimate heating temperature at manufacturing time through the result of the experiments, XRD and changed absorbing ratio from re-firing.

The operation of formwork has significant effects on the total structural construction cost and duration. Therefore, It's important to select proper formwork method in the planning phase. Especially in the residential-commercial building, as the customers' demands for various floor shapes and stories are getting higher, selecting formwork method is getting harder. The existing researches are focused only on the considerations for selecting formwork method or the decision support model for slab formwork. In this study, we developed a decision support model for the selection of exterior wall formwork in commercial residential building construction. The purpose of this model is to help the decision maker select the most suitable formwork method, which reflects various site conditions by using Delphi method. The type of formwork methods we considered are Gang Form, A.C.S, G.C.S, and R.C.S that are well used in these days. This proposed model is expected to increase the efficiency of whole construction project by selecting optimal method.
