鋼筋混凝土翼牆補強校舍之側推分析

Simplified Pushover Analysis for School Building Retrofitted by Reinforced Concrete Wing Wall

指導教授 : 鍾立來

摘要


在921大地震中,許多的國中小校舍受到損害,因此學者們提出補強方法提升校舍的耐震能力,其中翼牆補強能使校舍的韌性與強度有所提升。然而在補強之後,我們可以對結構物進行側推分析來了解結構的行為,本文所用的側推方法分別為傳統簡易側推、套裝軟體ETABS以及傾角變位法側推分析,其中傾角變位法側推是在某些前提假設之下以傾角變位法為基礎之方法,此法不僅適用於弱柱強梁的結構,同時也適用於強柱弱梁的結構。相較於實驗結果,傳統簡易側推對於弱柱強梁之結構會過於高估其強度與勁度;ETABS分析以及傾角變位法側推在強度、勁度與韌性上皆其分析結果皆趨於保守。

Lots of elementary and secondary school buildings were damaged by the devastating 921 Chi-Chi earthquake, so scholars proposed retrofit methods for increasing the seismic performance of school buildings, and the retrofit method by RC wing wall at columns can increase ductility and strength of buildings. After retrofitting by wing wall, the simplified pushover analysis can be done to understand the behavior of the structure. The simplified pushover analysis methods used to analysis the structure in this thesis are conventional simplified pushover analysis, slope-deflection pushover and software ETABS. Slope-deflection pushover is based on slope-deflection method with some assumptions. It is not only suitable for weak-column-strong-beam buildings but also strong-column-weak-beam buildings. Compared with experimental result, conventional simplified pushover analysis overestimates the strength and stiffness of the weak-column-strong-beam building. The strength, stiffness and ductility of ETABS analysis and slope-deflection pushover are conservative.
