Gil, Yong-Sik ; Hwang, Kyu-Seok ;
Journal of the Architectural Institute of Korea Structure & Construction, volume 29, issue 8, 2013, Pages 3~10
Wind force coefficient of tubular steel pole shows several characteristics when shape of section and angle of wind direction are changed. In this study, wind force characteristics of tubular steel pole are evaluated using different wind speed and angle of wind direction in wind tunnel test. Three types of tubular steel pole was selected for the experiment which were actually used at construction. For each type of model, entire model and cross-section model was made to experiment. The experiment on cross-section model is changing angle of wind direction from zero degrees to thirty degrees and changing of wind speed from 1 m/s to 18 m/s, and entire model is changing angle of wind direction from zero degrees to ninety degrees. From the result, wind force coefficient of tubular steel pole can be used as preliminary data to decide tubular support's wind load.

The voided slabs have advantages that its self-weight does not greatly increase notwithstanding the increase of its thickness and its flexural performance does not significantly decrease in comparison with normal reinforced concrete slab. However, the utilization of the voided slab is currently being underestimated in spite of structural system that enables economic design of building and construction of eco-friendly structure. Because the method of structural analysis and design for the voided slab is not established. The existing evaluation method of flexural strength of the voided slab considering only compressive zone above the voided part is conservatively evaluated. In this study, the practical compressive zone of the voided slab are considered to evaluate its flexural performance based on neutral axis location. The voided ratio is less, neutral axis location is deeper. Flexural performance of the voided slab is defined as T section is a little larger than its flexural performance that is defined as rectangular section.

The seokbinggo structures have the various construction types with the several configuration members and suffers the upper earth pressure. So, the seokbinggo structures show the different structural characteristics and the various load transfer mechanism. Especially, this study presents the discrete element method for the discontinuous elements and joints according to the discontinuum behavior characteristics in the masonry stone structures. Therefore, this study selects the representative seokbinggo structure and then considers the various design variables according to the construction types. Finally, this study analyzes the structural behavior characteristics of seokbinggo structures through the discontinuum structural modelling and analysis.

According to IEA (International Energy Agency), carbon dioxide (
) emissions due to the energy consumed by buildings are accounted for about 24% of the total
emissions. Extensive studies related with reducing
emissions have been carried out after the 2000s. For the environmentally sound and sustainable development, it is considerably important to design buildings considering
emissions in the conceptual design stage. Especially, unlike the steel structures,
emissions are different for each material (e.g. steel and concrete) used in the reinforced concrete (RC) structure. So, the volumetric ratio occupied by each material will have an effect on
emissions. In other words, it is necessary to know the
emissions relationship between two materials in order to reduce
emissions of RC structures. This study is on target to investigate
emissions of steel and concrete depending on material strengths and loading conditions in RC columns.
Structural Performance Evaluation of Arching Brackets for Earth-Anchors
Chun, Sung-Chul ; Kim, Young-Ho ;
Journal of the Architectural Institute of Korea Structure & Construction, volume 29, issue 8, 2013, Pages 53~60
Earth anchors used in retaining walls are usually terminated at steel brackets and the brackets have a rectangular section and triangle elevation (box-shaped bracket). As structures become large, the usage of the brackets increases and a flexibility of the brackets for applicable to various field conditions is required. A new bracket with an arch shape of plates (arch-shaped bracket) was recently developed and it can be applied at any angles of the earth anchor. The load bearing capacities of the arch-shaped bracket were experimentally evaluated under monotonic and cyclic loads and compared with the load capacity of the box-shaped bracket. Test results showed that the arch-shaped bracket had a higher load bearing capacity even though it is lighter than the box-shaped bracket. The arch-shaped brackets have stiffeners to reinforce the plates at the loading area and bottom area where higher stresses were concentrated. Due to the stiffener and the arch shape of the plates of the arch-shaped bracket, the plates yielded before the brackets reached their maximum strengths. Considering a safety factor 1.5 for temporary structures, the arch-shaped bracket has a design strength of 600 kN. Under 30 times of cyclic loads, the arch-shaped brackets maintained their load bearing capacities equal to the strengths under monotonic loads.

This paper estimates the bond performance of precast reinforced concrete beams with ground granulated blast furnace slag (GGBS). Bond tests proposed by Ichinose are carried out to estimate the bond performance of precast reinforced concrete beams according to replacement ratios of GGBS. A total of four specimens are designed in order to estimate the bond properties of top and bottom bars of specimens. The bond test results revealed that the specimens with GGBS showed similar bond performance compared to the specimen with Portland cements alone, regardless of the replacement ratio of GGBS. Furthermore, bond strength enhancement of the bottom bars relative to the top bars was found to be approximately 20% on average for all specimens.

Various programs have been developed to predict the energy consumption of a building as a result of recent increased social interest in the environmental friendliness of construction as measured by energy efficiency. The goal of environmental-friendliness, which is achieved by predicting the energy consumption of a building, can be realized in the design stage by applying a variety of technologies, planning factors and planning systems. However, most energy analyzing engines are only suitable for use in the advanced stages of design because of the large amount of design information that must be entered. Thus, because the simulation programs currently used are not suitable for use in the early stages of design, this study suggests a prediction logic that provides an overview of the energy consumption of a building according to its size, scope, and purpose by analyzing statistics collected by government agencies.

In this paper, a comparative cold weather concrete member test was conducted with gang form and euro form, which are generally used as forms for construction in Korea. Three members were fabricated for the comparative test: the member with the general gang form and euro form, the member with the existing insulation gang form on the outside and the general form on the inside, and the member with the existing insulation gang form on the outside and the newly developed insulation euro form on the inside. In this test, ready-mixed concrete with a nominal strength of 24 MPa that met a certain standard was cast in the cold weather concrete condition at a temperature of
), which is lower than the cold weather concrete management standard temperature in Korea
mean daily temperature. The standard water curing compressive strength, core compressive strength and temperature history were measured and comparatively examined for the general gang form-general euro form and insulation gang form-general euro form members that were cured at a certain inside temperature, and for the insulation gang form-insulation euro form member that was cured without additional temperature control.

To evaluate the stress-strain relationship of heavyweight concrete (HWC) and formulate a reasonable model, 26 mixes were prepared under various parameters including water-to-binder ratio, replacement level with natural aggregate for magnetite aggregates, and the replacement level of fly ash. Based on the current test results and existing data, modulus of elasticity, and strains at the peak stress and at 50% of peak stress in the descending branch were formulated as a function of compressive strength and unit weight of concrete. The factor to determine the slopes of ascending and descending branches of the stress-strain curve was solved by numerical analysis and formulated through the parametric study. Test results demonstrated that the stress-strain behavior of concrete is significantly affected by its unit weight as well as its compressive strength. ACI 349-06 provision unconservatively predicts the modulus of elasticity of HWC, and CEB-FIP and EC2 provisions overestimate the strain at peak stress. Meanwhile, the proposed models are in good agreement with test results, giving a consistency with the trends observed in tests.
