轴压比是影响剪力墙抗震性能的重要因素之一，研究轴压比对剪力墙抗震性能的影响是剪力墙抗震设计的重要内容。通过低周反复试验研究了实际轴压比分别为0．14、0．28、0．43和0．57的4片矩形截面剪力墙的抗震性能，包括水平承载力、顶点力-位移关系、刚度变化规律、黏滞阻尼系数变化规律等。收集了19个相关试验数据，研究了轴压比与承载能力以及水平位移角的关系。
軸壓比是影響剪力牆抗震性能的重要因素之一，研究軸壓比對剪力牆抗震性能的影響是剪力牆抗震設計的重要內容。通過低週反複試驗研究瞭實際軸壓比分彆為0．14、0．28、0．43和0．57的4片矩形截麵剪力牆的抗震性能，包括水平承載力、頂點力-位移關繫、剛度變化規律、黏滯阻尼繫數變化規律等。收集瞭19箇相關試驗數據，研究瞭軸壓比與承載能力以及水平位移角的關繫。

The axial compression ratio is one of the most important factors to affect the seismic performance of shear walls , studying on the seismic performance of shear walls under varied axial compression ratios is the key to seismic design of shear walls .4 pieces shear walls with rectangular cross-section under actual axial compres-sion ratios about 0.14, 0.28, 0.43 and 0.57 have been tested, the lateral bearing capacity, force displace-ment relationship , stiffness degradation , change of viscous damping coefficient of shear walls have been stud-ied.Also 19 related test data have been collected to find out the relationship between axial compression ratios and lateral bearing capacity , angle of lateral displacement .
