摘要

本文中針對國內中低層RC建築物數種常見之結構型式進行分析。研究中分別以定量方式探討結構物之基本振動週期、在地震中之受力大小、以及應變能之分佈狀況，並根據ATC-40中所建議之非線性分析方法來評估不同型式之結構物在地震中發生破壞的可能性。研究中並以符合現行耐震設計規範規定之結構物進行分析，以作為工程師在進行結構設計時的參考。

This research is to study the seismic behaviors of low-to-mid-rise concrete buildings of various configurations based on their dynamic properties, strain energy distribution, and capacity-demand spectrum relationships. Comparisons were made between structural models to evaluate the vulnerability of different building types under seismic loading. Conclusions of this study provide a reference for both researchers and engineers on their future works.
