摘要

通过有限元方法研究了单边螺栓T型节点在火灾高温下的拉伸性能。用常温下节点拉伸试验对有限元模型进行了验证

结果表明该有限元模型可准确模拟单边螺栓T型节点的拉伸性能。采用恒温加载的方式

研究了T型构件翼缘板厚度和火灾高温对节点抗拉性能的影响。T型翼缘板厚度分别取6、18、27mm

温度分别取常温至800℃共8种不同温度

并且通过改变材性考虑不同温度对钢材强度和刚度的折减。将不同T型翼缘板厚度和温度下节点的破坏模式、抗拉强度及刚度进行比较

得出了翼缘厚度和温度对其抗拉性能的影响

进而得出该单边螺栓T型节点在火灾作用下的拉伸性能。研究结果表明

该单边螺栓连接方式

在火灾下可以提供足够的锚固力

适用于闭合截面钢构件

如钢梁和钢管柱之间的连接。

Abstract

The tension behavior of one-side bolted T-stub in a fire was investigated by the finite element models（FEMs）.The FEMs were verified by the results of tension tests carried out at ambient temperature;the comparison showed that the FEMs could predict the tension behavior of the one-side bolted T-stub accurately.Using the steady state analysis

the effects of T-stub flange thickness and high temperatures on the behavior of bolted T-stub were investigated.During the analysis

the T-stub flange thickness was set as 6 mm

18 mm and 27 mm respectively

and eight different temperatures varying from ambient temperature to 800℃ were considered.In addition

the effect of high temperature was considered through changing the mechanical properties of steel.The failure modes

tension strength and stiffness of T-stub under different flange thicknesses and temperatures were presented

and the tension behavior of one-side bolted T-stub in a fire was obtained eventually.Research results proved that threaded holes could provide enough clamping force in a fire.Hence

the one-side bolted T-stub was suitable for the connection of closed-section steel members such as the connection of steel beam and tubular column.
