整浇梁板的框架节点抗震研究

Aseismic Research on RC Frame Joint of Monolithically Casted Slab

在梁与板整浇的和没有板的两种钢筋砼框架节点对比试验的基础上，本文研究了整浇梁板框架节点中，板对提高梁端正截面受弯承载力的作用和对节点抗震性能的影响；同时还研究了节点核心区采用钢纤维高强砼对节点抗震性能的改善；最后对整浇梁板的框架节点提出了设计建议。

Two reinforced concrete frame joint models with and without monolithically casted slab have been tested. According to these contrast experiments, the effect of the slab on the resisting moment capacity at the end section of beam as well as on the aseismic function of the joints are examined. The improvement of the aseismic function using high strength steel fibre reinforced concrete in the core is also studied. Finally, some design proposals are put forward.
