［摘要］基于現(xiàn)場(chǎng)試驗(yàn)，對(duì)實(shí)測(cè)風(fēng)荷載作用下大跨度索結(jié)構(gòu)避難帳篷的頂點(diǎn)位移進(jìn)行測(cè)量，分析風(fēng)速對(duì)頂點(diǎn)位移的影響，得出了實(shí)測(cè)風(fēng)荷載與結(jié)構(gòu)頂點(diǎn)位移之間的關(guān)系。應(yīng)用ABAQUS有限元軟件對(duì)風(fēng)荷載作用下的大跨度索結(jié)構(gòu)避難帳篷的頂點(diǎn)位移進(jìn)行有限元計(jì)算，有限元計(jì)算結(jié)果與試驗(yàn)結(jié)果具有較好的一致性。通過(guò)降低腳手架材料的剛度，模擬不同剛度條件下結(jié)構(gòu)的風(fēng)載位移響應(yīng)；并模擬了雪荷載以及溫度荷載作用下大跨度索結(jié)構(gòu)避難帳篷的受力性能。研究結(jié)果表明：大跨度索結(jié)構(gòu)避難帳篷的抗風(fēng)、抗雪荷載性能以及溫度荷載作用下的變形幅度均能達(dá)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.

Keywords: large-span; cable structure; tent; field experiment; finite element simulation; ABAQUS
