The purpose of this experimental study is to evaluate flexural behavior of reinforced concrete beams using Recycle Coarse Aggregate (RCA) with the Minimum Reinforcement Ratio (M.R.R) specified in KBC 2009 code equation. In the experiment, nine beam specimens fixed with
and design compressive strength of concrete (32MPa) were substituted with 0%, 30%, 50% of RCA and were used with 100%, 75%, 50% of M.R.R. The test value compared with the theoretical value has enough safety margin although theoretical value compared with the code calculation value has not enough safety margin when it is M.R.R of 75% and 50%. Howerever, theoretical value compared with code calculation value has enough safety margin at the M.R.R of 100%.

The research intended to search the optimal section area apportionment of columns and shear walls for improvement of lateral stiffness in frame-shear wall structure, using MIDAS-Gen. In this study, the main variables of analysis research were the section area ratios of column, the change of section area between the upper and lower columns and the change of thickness between the upper and lower shear walls. In order to find out the optimal section area apportionment of columns and shear walls for improvement of lateral stiffness in frame-shear wall structure, we examined the 30 stories reinforced concrete building. The results of this analysis study indicated that the section area ratios of column, the change of section area between the upper and lower columns, the change of thickness between the upper and lower shear walls had an impact upon the lateral stiffness in frame-shear wall structure. Moreover, it is showed that the research results can give help in obtaining the structural design data for finding out the optimal section area apportionment of columns and shear walls for improvement of lateral stiffness in frame-shear wall structure.

In this study, the dynamic unstable phenomenon and critical load variation of the spatial truss under the beating-wave load were researched. For this purpose, a non-linear governing equation of a shallow spatial truss was derived. In addition, a dynamic analysis and a characteristic analysis of the buckling phenomenon were conducted using the numerical method. The analysis model was selected considering the number of free nodes and the rise-span ratio, and the response to the periodic parameter that determines the period of the beating function was analyzed. To compare the results, a analysis for the step load and sinusoidal-wave load were also conducted. Resonance was observed in the analysis results for both the sinusoidal-wave load and the beating-wave load. The patterns of critical load level were similar in the area lower than the natural frequency, but they were different in the area above it. Furthermore, the critical level of the beating-wave load changed more sensitively than the sinusoidal-wave load did and was much lower than the step load.

Modern society, with the development of technology, desire for public benefits is increasing, dependence, such as infrastructure and public services is increasing. This is that the paralysis of national infrastructure systems, such as infrastructure and public services is likely to cause a national and major social turmoil. In this study, according to the method of the business impact analysis to provide in the ISO continued to maintain the operations and services of the H institutions, presented the basic data necessary to build the Business continuity management system in order to provide to.

Palm Oil Fuel Ash (POFA), a pozzolanic material based on biomass, have been studied in many countries. However, researches about microstructure of POFA are insufficient. Therefore, in this study, hydration properties of POFA were assessed by using many test and Flyash was set as control group. Type 1 portland cement was replaced by POFA and Flyash at 0%, 10%, 20% by weight of binder. A water to binder ratio(W/B) of 0.5 was used for all cement mortar with POFA and Flyash according to KS L ISO 679 and Compressive Strength, Mercury Intrusion Porosimetry(MIP), TG/DTA, X-ray Diffraction(XRD) and Scanning Electron Microscope(SEM) were conducted. The results showed that mortars with POFA had bigger engineering performance than ones with Flyash and the mortar with POFA at 10% by weight of binder had the highest compressive strength due to formation of
and C-S-H in the early ages and dense structures. Formation of
and C-S-H was confirmed by using TG/DTA, XRD and SEM. Dense structures were confirmed by MIP. Through all the results, it was concluded that the best replacement ratio of POFA was 10% by weight of binder.

Recently as a way to overcome the limitations of fiber-reinforced concrete(FRC), it is considered that development possibility of HPHRC(High Performance Hybrid fiber Reinforced concrete) is high, because HPHRC containing one or more type of fiber which differ in length and mixing proportion permits to control the structural cracks and increase the toughness of the concrete composites. However the existing researches which excludes the influence of the compressive strength are far from practical application. This paper is a fundamental study on the compressive strength properties to induce a high strength and flexibility of HPFRC. So it concentrates on highlighting mechanical property of high strength mortar reinforced by hybrid fiber.

Although it is reported that vacancy and lease rates of office buildings could be improved remarkably due to after remodeling work, it is difficult for the remodeled office buildings to incorporate such profitable improvement appropriately into wherein the real estate appraisal for them was conducted. Based on income capitalization method, which is one of the three current appraisal methods and considering as a proper candidate in conducting appraisal for the remodeled buildings, this paper aims at clarifying how the method can evaluate the monetary value of the remodeled office building accurately. For achieving such objective, i) the method (i.e., income capitalization method) was applied to the 25 remodeled office cases available with their market price in order to calculate their appraisal prices, ii) a comparison between the projected price by appraisal and real market price was conducted, and iii) the comparison result was analyzed in terms of how the appraisal method calculates the price for the remodeled office buildings accurately. In conclusion, it is revealed that income capitalization method can evaluate the price of the remodeled office buildings relatively accurately (9.46% of error rate in average).
