Abstract: In regions experiencing high-frequency earthquakes, it is necessary to reevaluate the seismic performance of nuclear power plant buildings. In the evaluation of equipment, as well as the structure, the damping ratio of a ...

Abstract: To accurately predict the inelastic earthquake response of a structure by pushover analysis, the prescribed load profiles should be consistent with the actual force profiles which develop maximum design values during the ...

Abstract: An experimental study was performed to investigate the potential maximum ductility and energy dissipation capacity of steel plate walls with thin infill plates. Three specimens of a three-story steel plate wall were tested. ...

Abstract: An experimental study was performed to investigate the structural capacity of steel plate walls with various infill plate designs. Five three-story steel plate shear walls with thin infill plates were tested. The parameters ...

Abstract: A hysteresis model for thin infill steel plates was developed to evaluate the nonlinear cyclic behavior of steel plate shear walls. Nonlinear finite-element analysis was performed for thin steel plates with a rigid boundary ...

Abstract: Longitudinal elongation develops in reinforced concrete members that exhibit flexural yielding during cyclic loading. The longitudinal elongation can decrease the shear strength and deformation capacity of the members. In ...

Abstract: An experimental study was performed to investigate the cyclic behavior of walls that are composed of reinforced concrete boundary frames and thin steel infill plates. For this purpose, three-story steel plate infilled walls ...

Abstract: For performance-based design of reinforced concrete moment frames, the inelastic load-displacement relationship including strength degradation of beam-column joints should be accurately defined. In this study, a simplified ...

Abstract: For better structural performance and constructability, a concrete-encased steel column that uses a steel cage prefabricated with bolt connections was developed. The steel cage consists of longitudinal steel angles and ...

Abstract: A steel–concrete composite wall with boundary elements of steel U-section was developed for high structural performance and efficient use of materials. Cyclic lateral loading tests were performed on the proposed walls to ...
