针对现有U形钢板-混凝土组合空腹夹层板楼盖结构体系在实际应用中存在的一些问题,提出了以H型钢组合结构构件替代原有空腹夹层板中的主要构件,形成了型钢混凝土组合空腹夹层板楼盖结构体系。同时结合实际工程案例将型钢混凝土组合空腹夹层板楼盖体系的分析、设计结果与U形钢板-混凝土组合空腹夹层板的设计结果进行对比,并对型钢混凝土组合空腹夹层板结构进行三向罕遇地震作用下的动力弹塑性分析。研究表明,在多层大跨度建筑结构中,型钢混凝土组合空腹夹层板受力性能良好,能满足结构的承载力要求和正常使用要求,在罕遇地震作用下,型钢混凝土组合空腹夹层板整体性较好,抗震性能良好,建议在跨度较大时选用型钢混凝土组合空腹夹层板结构。
Aiming at some problems existing in the practical application of the existing U-shaped steel plate-concrete sandwich panel structure system, the paper proposes to replace the main components in the existing sandwich panel with the H-section steel composite structure component, Mezzanine floor structure system. At the same time, the analysis and design results of the deck steel plate sandwich panel combined with the actual engineering case are compared with the design results of the U-shaped steel plate-concrete composite plate sandwich panel, and the sandwich panel structure of the SRCB plate is three- Dynamic Elastoplastic Analysis under Earthquake. The research shows that in the multi-storey long-span building structure, the load-bearing behavior of the SRC sandwich sandwich panel is good, which can meet the requirements of bearing capacity and normal use of the structure. Under the action of rare earthquakes, the integrity of SRCB sandwich panel Good, good seismic performance, it is recommended in the span of steel plate combination of fast sandwich plate structure.
