［摘要］針對(duì)現(xiàn)有U形鋼板-混凝土組合空腹夾層板樓蓋結(jié)構(gòu)體系在實(shí)際應(yīng)用中存在的一些問(wèn)題，提出了以H型鋼組合結(jié)構(gòu)構(gòu)件替代原有空腹夾層板中的主要構(gòu)件，形成了型鋼混凝土組合空腹夾層板樓蓋結(jié)構(gòu)體系。同時(shí)結(jié)合實(shí)際工程案例將型鋼混凝土組合空腹夾層板樓蓋體系的分析、設(shè)計(jì)結(jié)果與U形鋼板-混凝土組合空腹夾層板的設(shè)計(jì)結(jié)果進(jìn)行對(duì)比，并對(duì)型鋼混凝土組合空腹夾層板結(jié)構(gòu)進(jìn)行三向罕遇地震作用下的動(dòng)力彈塑性分析。研究表明，在多層大跨度建筑結(jié)構(gòu)中，型鋼混凝土組合空腹夾層板受力性能良好，能滿足結(jié)構(gòu)的承載力要求和正常使用要求，在罕遇地震作用下，型鋼混凝土組合空腹夾層板整體性較好，抗震性能良好，建議在跨度較大時(shí)選用型鋼混凝土組合空腹夾層板結(jié)構(gòu)。

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
