考虑板筋参与梁端承载力贡献的设计方法及抗震性能研究

通过考虑一定有效翼缘宽度范围的楼板内钢筋对梁端负弯矩承载力贡献并进行梁端配筋设计,研究楼板与梁的共同工作性能.应用对梁、柱采用考虑钢筋和混凝土的纤维梁模型,楼板采用考虑钢筋和混凝土的复合材料分层壳单元模型,建立可考虑楼板对梁刚度及承载力贡献的整体弹塑性有限元分析模型,对影响RC框架结构的屈服机制的主要因素进行了研究.不...

Study on Design Method and Seismic Performance in Consideration of the Contribution of Rebar in Slabs to the Bearing Capacity of Beams

By considering the contribution of rebar in the slab to the negative moment capacity of the beam within the scope of effective flange width to design the longitudinal reinforcement,the cooperation performance between slabs and beams was studied.Elastic-plastic finite element model was set up by considering the contribution of the slab to the stiffness and bearing capacity of the beam.In this model,fiber beam model was used to simulate the beam and column,and multi-layer shell was used to simulate the slab.T...
