지진응답평가를 위한 비선형 약산법의 오차해석 = The Error Analysis of Approximation Nonlinear Methods for Estimation the Seismic Response

다국어 초록 (Multilingual Abstract)

Recently, a variety of methods are proposed to solve the problems shown in a existing performance-based design of structure. The most accurate one among analysis methods for the performance evaluation of structure is nonlinear time history analysis. However, the approximate analysis methods in aspect of practicality and simplicity are needed. Even though there are linear capacity spectrum method and nonlinear capacity spectrum method through nonlinear static analysis as the representative approximate methods, a repetitive calculation process is consumed and the result is also likely to be inaccurate.
Therefore, this research presents nonlinear direct spectrum method which directly enables nonlinear maximum response to derive, after obtaining the yielding strength and the frequency of structure from pushover curves, without going through a series of calculation processes. Also, it is proposed to compare and examine the accuracy and practicality through an example structure.
