预制压型钢板混凝土组合板和钢梁连接及其有限元分析

为了满足预制组合板和钢梁连接节点的承载和变形要求，提出了一种新型的压型钢板混凝土组合板和钢梁整体预制的法兰板-螺栓连接节点.使用ABAQUS分别建立了现浇、预制节点模型，对比了两者在同等条件下的受力性能，并分析了栓钉数、组合板的厚度和长度、螺栓数和法兰板厚度对预制节点模型受力性能的影响.结果表明:预制节点的受力性能与现浇节点相似，设计预制节点时应采用96个栓钉、8个螺栓，以及200mm厚、5.1~6.6m长的组合板及10mm厚的法兰板.

Connection of Precast Profiled Steel Sheet Concrete Composite Plate and Steel Beam and Its Finite Element Analysis

In order to meet the load-bearing and deformation requirements of precast composite plate and steel beam connection joints， a new type of flange plate-bolt connection joint with integral precast of profiled steel sheet concrete composite plate and steel beam was proposed. The cast-in-place and precast joint models were established by using ABAQUS respectively， the stress performance of which under the same conditions was compared， and the influence of the number of studs， the thickness and length of the composite plate， the number of bolts and the thickness of the flange plate on the stress performance of the precast joint model was analyzed. The results show that the stress performance of the precast joints is similar to that of the cast-in-place joints. The precast joints with 96 studs， 8 bolts， 200mm thick， 5.1~6.6m long composite plate and 10mm thick flange plate are suggested to be used when design.
