[摘要]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。

Abstract:In order to improve several issues in the practical application of U shaped steel plate-concrete composite open-web sandwich plate, the steel reinforced concrete composite open-web sandwich plate in the floor structure system was presented. With a practical engineering, the design results of these two floors were compared in the last and the dynamic elastic\|plastic analysis under three seismic direction was also completed for the new structures. All of the analyses  were illustrated the new type of the open-web sandwich plate structure could meet the capacity requirements, normal serviceability requirements and the good dynamic performance was presented in the process. The structure also has better holistic performance and capacity of anti-seismic and can be introduced to use in the large span structures.

Keywords:steel reinforced concrete; large span; open-web sandwich plate; composite structure; dynamic analysis
