［摘要］基于现场试验，对实测风荷载作用下大跨度索结构避难帐篷的顶点位移进行测量，分析风速对顶点位移的影响，得出了实测风荷载与结构顶点位移之间的关系。应用ABAQUS有限元软件对风荷载作用下的大跨度索结构避难帐篷的顶点位移进行有限元计算，有限元计算结果与试验结果具有较好的一致性。通过降低脚手架材料的刚度，模拟不同刚度条件下结构的风载位移响应；并模拟了雪荷载以及温度荷载作用下大跨度索结构避难帐篷的受力性能。研究结果表明：大跨度索结构避难帐篷的抗风、抗雪荷载性能以及温度荷载作用下的变形幅度均能达到安全使用要求。

Abstract: Base on the field experiment, displacements of vertexes of the large-span cable shelter tent were measured under the action of wind load, and the influence of wind speed on displacements of vertexes was analyzed, then the relationship between wind load and displacements of vertexes was got. The finite element software ABAQUS was adopted to calculate displacements of vertexes of the large-span cable shelter tent under the action of wind load, and results achieved by the finite element analysis are well consistent with values got by the field experiment. Then wind load-displacement response for the largespan cable shelter tent was simulated in different stiff conditions by reducing the stiffness of scaffold and its stress performance was also simulated respectively under the action of snow load and temperature load. Research results show that wind load and snow load resistance of the large-span cable shelter tent and its deformation amplitude under the action of temperature load can meet requirements for safe use.
