Application of Nonlinear Static Analysis and Nonlinear Dynamic Analysis in Building Seismic Performance: A Review
摘要
This study explores the application of nonlinear static analysis, also known as pushover analysis, and nonlinear dynamic analysis, or time-history analysis, in various contexts. Pushover analysis, a type of nonlinear research, determines the structural capacity by incrementally increasing static horizontal loads until the structure collapses. This method is gaining traction as a simplified computational approach for assessing the seismic performance of buildings. The primary objective of this research is to conduct a comparative study of the application of pushover analysis and time-history analysis. Nonlinear static analysis evaluates existing buildings’ global behavior and seismic capabilities under lateral stresses, often resulting from earthquake forces. As such, static pushover analysis is becoming increasingly popular as a straightforward computational method for evaluating a building's seismic performance. On the other hand, nonlinear dynamic analysis methods, while comprehensive, are time-consuming and complex. Predicting the extent of structural damage from ground motion can be challenging. Therefore, there is a significant value in developing a more straightforward computational system for evaluating the seismic performance of structures. This comparative study aims to highlight the benefits and limitations of both methods, contributing to the ongoing evolution of seismic performance assessment techniques.
