The purpose of this study is to present the new effective stiffness of special RC shear walls with flanges. ACI 318-99 adapt the different design provisions of effective stiffness between simple walls and walls with flanges. But domestic code makes no distinction between simple and with flanges walls. By the nonlinear analysis, maximum loads and displacement are calculated. Therefore the moment-curvature curve is calcultaed by the P-Δ curve. The stiffness ratios of cracked and uncracked section are calculated by the moment-curvature curves. And the stiffness ratios of simple walls and wall with flange are compared.

When the story lateral forces of multi-story frame were not distributed properly during a seismic design, sufficient seismic performances should not secured. Thus, studies on the distribution of story lateral forces that make the uniform distribution of story damage are positively necessary. In this study, a lot of dynamic analyses of multi-story frames were conducted using various seismic waves to find the optimum distributions of story damage and the distributions of story shear in that circumstance were calculated.

The current seismic design code prescribes structural wall should be designed as special shear wall when building height is more than 60m and seismic design category D. The design code for the irregular wall is not provided. Therefore, the special wall with flange is designed as linear section wall. The ultimate strain of concrete in nonrectangular section would be different form that in rectangular section, then the equation of discrimination for special wall would changed. In the study, nonlinear analysis for linear and irregular wall are performed, and concrete ultimate strain is compared.

Even though the need for application of damping devices is being raised even in Korea, the design process for damping system is usually performed without considering not only if the design base shear has been reduced in proper ratio, but also if the response reduction due to the application of the damping device has been actually occurred. In this research, response reduction effect was checked as a reduced base shear force, energy approach, and logarithmic decrement approach for the bearing wall apartment buildings with fluid damper.

The collapse capacity of a prototype low-rise steel moment resisting frame was evaluated with incremental dynamic analyses of FEMA-P695. Structural elements of the frames were modeled using FEMA-356 and forty ground motion records were selected and scaled to meet the Korean seismic hazard. The collapse capacity of the prototype frame does not meet with the collapse performance criteria defined in FEMA-P695

The purpose of this study is to verify a RCS strengthening method for Medium & Low-rise R/C buildings using the nonlinear analysis. In this study, a three-story R/C building that represents a typical Korean school constructed in the 1980s was selected. Seismic capacities of the building before and after RCS strengthening are evaluated based on the nonlinear static and dynamic analyses.

Since Mt. Baeck-du is considered to be 8 or more in VEI scale, it is obviously crucial work to understand the dynamic characteristics of volcanic earthquakes for prediction of the possible damage in South Korea due to the future eruption of Mt. Baeck-du. This study aims to investigate the dynamic characteristics and propose design response spectrum for volcanic earthquakes.

The purpose of this study was to evaluate the seismic performance of high-performance steel. For this study, the hysteretic behavior and deformation shape of steel beam-to-column connections with SM570TMC was investigated using non-linear finite element analysis. The non-linear finite element analysis was carried out using ANSYS. The displacement analysis of steel beam-to-column connections was conducted according to the qualifying procedures of current korean building code(KBC2009).

In this papery, integrated optimization of structure-smart control device is conducted and possibility of reduction of structural resources of a tall building with additional smart damping device has been investigated. For this purpose, a 60-story diagrid building structure is used as an example structure and artificial wind loads are used for evaluation of wind-induced responses. Because dynamic responses and the amount of structural material and additional smart damping devices are required to be reduced, a multi-objective genetic algorithm is employed in this paper.

Adaptability of a smart top-story isolation system for reduction of seismic responses of tall buildings in regions of low-to-moderate seismicity has been investigated in this study. To this end, 20-story example building structure was selected and an MR damper and low damping elastomeric bearings were used to compose a smart base isolation system. Artificial earthquakes generated based on design spectrum of low-to-moderate seismicity regions are used for structural analyses.

Recently, Seismic design criteria for major domestic structures has been being improved constantly, because the importance of seismic design for major public infrastructures is largely recognized. A preliminary assessment of the seismic performance for the existing rapid-transit railway tunnel, a precedent task before conducting a detailed assessment, can be use as the standard of judgement to decide whether to perform a detailed assessment or not. On the other hand, There are no reasonable study in this area. In this study, an assessment method was presented to evaluate a seismic performance of the existing rapid-transit railway tunnels which seismic design are not performed more economically and rationally.

To evaluate the displacement dependence capacity of steel plate metallic damper, which has I shape strut, performance test is conducted with the target displacement variables on constant velocity. From test results, larger target displacement(50mm) shows lower cyclic numbers and cumulated energy dissipated area than lower target displacement(25mm). Also it shows higher strength and early failure than short target displacement

In this paper, the seismic performance of FCW apartment building with porous hysteretic damping system(PHDS) is examined by comparing with the building designed by KBC2009. The results show that even though the seismic force-resisting system is designed to reduce the design seismic base shear by 75 percent, the building with PHDS is enough to satisfy the performances required by the national seismic code

The previous design of the shear key is designed by considering only the strength of the anchor the body. However, the strength of the anchor portion often be influenced by steel strength of the anchor, as well as the strength of the concrete around the anchor. The purpose of this study was to improve the problem of the existing design methods by considering the performance of the shear key body and the anchor system.

The application of a base isolation to nuclear systems should be considered in lots of view points of operation at the stage of design before construction. Those points includes protection and maintenance of isolators for a seismically isolated nuclear power plant. The methodology suggested in this paper is applicable for any type of isolators in which an isolated structure part is easily replaced and confined pressure can be easily controlled with a height-adjustable part. The height-adjustable part being adjusted by suppling or discharging fluid therein or therefrom
