摘　　要：为研究装配式剪力墙结构中预制内嵌外围护墙对主体结构抗震性能的影响,完成了3个含不同构造围护墙的两层足尺墙体试件和1个无围护墙对比试件的拟静力试验。试验结果表明:含独立式围护墙和一体式围护墙的试件表现为围护墙与结构构件整体受力并发生破坏,承载力分别为无围护墙试件的2.2倍和2.3倍,位移角为1/2000时的平均割线刚度分别为无围护墙试件的2.8倍和3.5倍,极限位移角分别为无围护墙试件的0.58倍和0.43倍;与含独立式围护墙和一体式围护墙的试件相比,含优化构造围护墙的试件避免了不利的破坏模式,承载力及刚度显著减小,变形能力增大至与无围护墙试件相当。基于试验结果,建议工程中优先采用优化构造,当采用未优化的构造时应在整体结构分析中考虑围护墙的影响,并采取相应的加强措施。To study the effects of embedded enclosure walls on the seismic behavior of main structure in assembled shear wall structure,quasi-static tests of three full scale two-story wall specimens with different enclosure walls and one comparison specimen without enclosure wall were completed.The test results indicate that the enclosure wall bears load and fails with structural elements integrally for the specimen with independent enclosure wall and the specimen with integrated enclosure wall,the load-carrying capacities of specimens with independent enclosure wall and integrated enclosure wall are 2.2 times and 2.3 times of the specimen without enclosure wall,respectively,the two specimens′mean secant stiffnesses when drift is 1/2000 are 2.8 times and 3.5 times of the results of the specimen without enclosure wall,and the ultimate drifts are 0.58 times and 0.43 times of the results of the specimen without enclosure wall.Compared with the specimens with independent enclosure wall and integrated enclosure wall,adverse failure mode was avoided for the specimen with optimized enclosure wall,the load-carrying capacity and stiffness decreases dramatically,the deformability increase to the level as large as the specimen without enclosure wall.Based on the test results,it is suggested that the optimized enclosure wall should be adopted preferentially,the effects of enclosure walls should be considered in structural analysis and corresponding strengthening measures should be taken when the enclosure walls without optimization are used.
