Abstract

Structural analysis is performed to understand the seismic performance of the structure, and nonlinear time history analysis is performed for clearer analysis. When performing nonlinear time history analysis, it is reviewed whether the design earthquake wave has a value above a certain level for the response spectrum of the target ground. The seismic performance of the structure is determined by the maximum rotation angle of member for each direction generated during the duration of the seismic wave. However, in the current KDS 41 17 00, there is no mention of the duration of the design earthquake wave. The review range for seismic wave duration is reviewed in accordance with ASCE 4-98 for 5%-75% of Arias Intensity and 5%-95% of the integrated area of seismic waves. Nonlinear time history analysis is performed on a 5-story reinforced concrete structure using the selected design earthquake wave. As a result of the analysis, the timing of determining the seismic performance level of the structure is different for each seismic wave, but using an earthquake wave calculated below 67.72% of Arias Intensity of the original seismic wave may result in different results.
