【摘要】 提出一种整间装配式轻钢龙骨组合外挂墙板，并设计了用于墙板与钢框架之间连接的一种新型滑移节点。通过足尺静力荷载试验研究墙板在风荷载下的力学性能并通过ABAQUS建立外挂墙板-钢框架结构体系模型，重点分析了龙骨壁厚及竖龙骨间距对墙板抗风性能的影响以及不同材料间的协同工作机理，并对龙骨布置进行优化。结果显示：在9级风吸/压荷载下，整间外挂墙板保持弹性，体系抗风性能优越；龙骨壁厚减至0.6 mm，竖龙骨根数减至8根时，仍满足规范要求。风荷载下墙板面外承载主要由龙骨骨架承受，覆面板和泡沫混凝土次之。更多还原

【Abstract】 A novel type of whole-room external prefabricated light steel keel composite wall panel is proposed,along with a newly designed sliding joint for connecting the wall panel to the steel frame. The mechanical properties of the wall panel under wind load were investigated through full-scale static load tests, and a structural system model of the external wall panel and steel frame was established using ABAQUS. The study focused on analyzing the impact of keel wall thickness and vertical keel spacing on the wind resistance of the wall panel, as well as the cooperative working mechanisms between different materials, leading to an optimized keel arrangement. The results indicate that the whole-room external wall panel remains elastic under 9th-grade wind pressure/suction load, demonstrating superior wind resistance performance. Even when the keel wall thickness is reduced to 0.6 mm and the number of vertical keels to 8,the system still meets the standard requirements. Under wind load,the external load on the wall panel is primarily borne by the keel frame,with the cover panel and foam concrete contributing secondary support.更多还原
