中文摘要:

为研究现浇剪力墙装配整体式框-剪结构的抗震性能,对2榀(其中1榀为装配式试件PCFW1,1榀为全现浇试件RCFW)1/2比例两层两跨混凝土框-剪结构试件进行拟静力试验,研究其破坏过程和机理、滞回性能、延性、耗能能力和塑性铰发展情况等.结果表明:装配式试件PCFW1与全现浇试件RCFW相比,其破坏过程、破坏机制和最终破坏形态基本相同.装配式试件PCFW1与全现浇对比试件RCFW的滞回曲线均较为丰满,试件的屈服荷载、峰值荷载、极限荷载均略大于全现浇试件RCFW的相应值,但其差值均小于10.0%,延性低于全现浇试件RCFW;灌浆套筒可以有效传递纵向钢筋应力;现浇剪力墙装配整体式框-剪结构中,顶层边节点处梁上钢筋弯锚可用钢筋焊端锚板代替.

英文摘要:

To investigate the seismic performance of precast frame-shear wall structures comprised of cast-in-place concrete shear walls and prefabricated frame components, two 1/2 scale test specimens were fabricated and carried out under quasi-static reversed cyclic lateral loading in laboratory. One specimen named PCFW1 is a precast structure comprised of cast-in-place concrete shear walls and prefabricated frame components,and the other one named RCFW is a conventional cast-in-place concrete one, which is used as a reference specimen,all two test specimens are two bay-two story RC specimens.Some important characteristics such as failure process, failure mechanism, hysteretic response, displacement ductility, energy dissipation capacities and plastic hinge development process were studied. The test results show that the test specimen PCFW1 have similar failure mode compared with the test specimen RCFW.The lateral load-displacement hysteretie loops of both specimens are Dlumt). The characteristic values of bearing capacity such as yield load, peak load, and ultimate load of specimen PCFW1 are larger than those of RCFW, but the difference is less than 10.0%.The displacement ductility of specimen PCFW1 is obviously less than that of RCFW;Grout-filled sleeves can transmit the longitudinal steel stress efficiently;The anchor bars in a knee connection in the top story can be replaced by bars wielded with anchor plate in precast shear wall-frame structures comprised of cast-in-place concrete shear walls and prefabricated frame components.
