新型装配式蜂窝板空腹屋盖结构的承载力试验研究
Experimental study on load capacity of new fabricated honeycomb panel open-web roof structures
摘要
Abstract
To assess the mosaic effect of a new assembly type space structure composed of metal ho-neycomb sandwich panel with high performance by a specific connection mode and study the me-chanical properties,failure mechanism and ultimate load capacity of the hollow roof structure,two open-web full scale box specimens with the plane size of 1 m ×3 m and the structural height of 300 mm are designed and fabricated.The corresponding theory analysis and experimental study of the ul-timate bearing capacity are carried out.The results show that the structure has a high load carrying capacity,reflecting the structural characteristics of lightweight and high strength.The failure is mainly caused by the buckling of the inner surface of the honeycomb panel.However,if the connec-tion strength is insufficient,the damage of the connecting member is prior to the buckling of the hon-eycomb panel,which is a negative damage pattern.The comparison results of the box specimens un-der different simulation analysis show that the finite element coupling method for simulating the working status of connection is simple and feasible,which provides a reference for the future design of these structures.关键词
