摘要

一般較低樓層的鋼筋混凝土建築物主要是由基本模態所控制，但是近年來隨著建築技術的進步，越來越高的鋼筋混凝土建築物隨處可見。因此當地震力來臨時，較高階的模態對於鋼筋混凝土建築物將會有頗高之影響，不可忽視之！
本研究以太平洋地震研究中心(PEERC)所提出模態側推分析(MPA)的理論為基礎，並與美國應用科技委員會(ATC)的學術研究報告ATC-40和美國聯邦緊急事務處理總署(FEMA)的學術研究報告FEMA-273所建議的數種側向力分布模式做一個比較，同時將多模態疊加法則運用於其中，最後再與時間歷時分析所得的結果做一誤差值的比較。
一般而言，靜力側推分析較時間歷時分析易為工程師所接受，因此本研究以靜力側推分析為主，時間歷時分析為輔，期望找出符合鋼筋混凝土建築物的側向力分布模式及組合方法，藉由靜力側推分析所得的結果模擬近似實際建築物承受地震力的動態反應。

General lower reinforced concrete buildings is controlled by basic mode, but construction techniques has progressed in recent years, high-rise reinforced concrete buildings can be seen everywhere. When earthquakes happened, higher mode is much more important in the high-rise reinforced concrete buildings and cannot be ignored.
This research is based on Modal Pushover Analysis (MPA) from Pacific Earthquake Engineering Research Center (PEERC), and compared with several force distributions form the report ATC-40 of Applied Technology Council (ATC) and the report FEMA-273 of Federal Emergency Management Agency (FEMA). Finally, modal combination rules will be used and compared with the results of time history analysis.
Generally, the static pushover analysis is more easily accepted than the time history analysis by engineer, so this research major is static pushover analysis, and the minor is time history analysis, expect to find out the force distribution and combination rules of the reinforced concrete buildings, and also used result of static pushover analysis to look like dynamic response of actual buildings under earthquakes.
