【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.
[Abstract]:In order to study the anti-seismic performance of the integral frame-shear structure for cast-in-place shear wall, the quasi-static test of two-layer two-layer two-layer two-layer two-layer two-layer two-layer two-layer concrete frame-shear structure test piece of the two-layer two-layer two-layer concrete frame-shear structure is carried out on the two-layer two-layer two-layer two-layer concrete frame-shear structure test piece of the two-layer two-layer concrete frame-shear structure test piece, The development of ductility, energy dissipation and plastic hinge. The results show that the damage process, the damage mechanism and the final destruction form of the fabricated test piece PCFW1 are the same as that of the full cast-in-place test piece RCFW. The hysteresis curve of the assembled test piece PCFW1 and the full cast-in-place test piece RCFW is full, the yield load, the peak load and the ultimate load of the test piece are slightly larger than the corresponding values of the full cast-in-place test piece RCFW, but the difference value is less than 10.0%, and the ductility is lower than that of the full-cast-in-place test piece RCFW; The grouting sleeve can effectively transfer the longitudinal steel bar stress; the cast-in-place shear wall is assembled with the integral frame-shear structure, and the steel bar bending anchor on the beam at the top edge node can be replaced by a steel bar welded end anchor plate.
