【摘要】：为研究采用灌浆套筒连接的全装配式框架-剪力墙结构的抗震性能,设计制作了1榀1/2比例两层两跨灌浆套筒连接全装配式框-剪结构模型试件PC-3,并对其进行了低周反复加载试验。通过与已有试验结果对比分析,研究了结构的破坏模式、滞回性能、刚度退化、位移延性和耗能能力等抗震性能指标。结果表明:灌浆套筒连接全装配式框-剪结构试件PC-3与全现浇试件RCFW的破坏模式基本相同,梁端塑性铰长度减小、位置外移,具有良好的耗能能力和较好的刚度特性,试件PC-3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5.0%,延性略小于全现浇试件RCFW,加载过程中耗能较为平稳。两种全装配式框-剪结构均具有良好的抗震性能,工程实践中可供设计人员选择采用。
[Abstract]:For the study of using seismic performance of assembled frame grouting sleeve connection of shear wall structure, designed and produced 1 pieces of the 1/2 scale two storey two span grouting sleeve connection assembled frame shear structure test model of PC-3, and the low cyclic loading tests are carried out on it. By comparing with the existing test results analysis. Study on the structure of the failure mode, hysteretic behavior, stiffness degradation, seismic performance indices of displacement ductility and energy dissipation capacity. The results show that the failure mode of the assembled frame shear structure specimen PC-3 and cast-in-place specimen RCFW grouting sleeve connection is basically the same, the beam plastic hinge length decreased position shift, has good energy dissipation capacity and good stiffness, PC-3 specimen yield load, peak load and ultimate load are slightly larger than the corresponding values of the cast-in-place specimen of RCFW, but the difference was less than 5%, slightly less than the ductility of cast-in-place RCFW specimens loaded The energy consumption is more stable in the process. The two fully assembled frame shear structures have good seismic performance, which can be used by designers in engineering practice.
