摘要

由於台灣位於環太平洋地震帶，地震發生頻繁，加上台灣地狹人稠，房屋密度極高，使得每每有較大之地震發生，受影響之人口眾多。而基於私密性與防水性的要求，台灣一般住宅建築中使用大量的鋼筋混凝土剪力牆，此類牆體具有極高之側向勁度與強度，於地震力作用下可有效控制結構物之側向位移，此特性將有利於避免其它豎向構材之破壞，而為結構抗倒塌破壞之關鍵構材，故了解剪力牆之破壞與倒塌行為極為重要。
鑒於目前國內外對於鋼筋混凝土剪力牆破壞與倒塌行為之相關試驗資訊較少，本研究設計四座鋼筋混凝土剪力牆以及一套配合實驗使用之鋼製模鋼製夾具於國家地震工程研究中心進行鋼筋混凝土剪力牆體之破壞與倒塌行為試驗。另外，透過收集國內外既有鋼筋混凝土剪力牆之試驗結果，進行鋼筋混凝土剪力牆破壞與倒塌行為之分析討論，並提出一針對鋼筋混凝土剪力牆倒塌位移之分析方法建議。

Located in Circum-Pacific Seismic Belt, Taiwan experiences earthquakes frequently. In addition, since Taiwan is a small island with such a large population, the density of buildings is extremely high, which leads to a bigger impact on the population whenever a large earthquake occurs. To fulfill the high demand of serviceability and water-resistance, huge amount of reinforced concrete shear wall were used in residential building in Taiwan. Also, the reinforced concrete shear wall, which has high lateral stiffness and capacity, can control the lateral drift of building and prevent the other vertical members from lateral failure. Therefore, the reinforced concrete shear wall is considered as one of the most effective earthquake-resisting members for collapse prevention. It has been widely applied in seismic design and retrofitting. As a result, it is crucial to understand the collapse behavior of reinforced concrete shear walls.
Given the fact that there is few related experimental information about the failure and collapse behavior of reinforced concrete shear wall locally and abroad, this research design contained four reinforced concrete shear walls and experiment with failure mode and collapse behavior of reinforced concrete shear wall by using a set of steel mold as well as steel beams at the National Center for Research on Earthquake Engineering. Moreover, based on the collection of test results of reinforced concrete shear walls locally and abroad, the analysis and discussion of the failure and collapse behavior of reinforced concrete shear walls are presented. Furthermore, a method for analyzing the collapse displacement of reinforced concrete shear walls is proposed.
