RC填充牆對鋼筋混凝土建築耐震能力之影響

Abstract

本論文是藉由SAP2000建構模型以進行側推之非線性靜力分析，探討四種不同的牆體配置加入舊建築物去做耐震能力補強，其中並用4種舊有建築物混凝土抗壓強度探討舊有建築物混凝土抗壓強度對補強效果的影響。另外也用7種土壤彈簧勁度來探討土壤－結構互制的影響，同時也探討在使用牆壁補牆後對緊鄰牆壁之基礎有何影響。

研究結果顯示，加入對稱的牆壁可以大幅度的提高結構物抵抗地震的能力，但是卻會造成基礎與地梁力量更大的增加，加入不對稱的牆壁不一定提高結構物抵抗地震的能力，仍然會造成基礎與地梁力量更大的增加，不同時做基礎補強無法提高結構物抵抗地震的能力。

The goal of this thesis is to investigate the increase of earthquake resistance capability by adding infill walls into beams and columns using pushover technique of SAP2000. Four concrete compressive strength of old building were used to explore the effect of concrete strength to the strengthing effect. Seven soil spring stiffness were used to investigate the influence of soil-structure effect. The influence to the foundation was studied too.

Research results shows that the adding of symmetrical infill wall can increase the earthquake resistance capability significantly. Non- symmetrical infill wall may not increase the earthquake resistance capability. Both cases increase the force on foundation several times. The adding of infill wall to increase the earthquake resistance capability has to strengthing the foundation in the same time.
