锈蚀H型钢偏心受压承载性能试验研究

Experimental Study of Bearing Performance of Corroded H-Type Steel Member Subjected to Eccentric Compression

通过锈蚀H型钢构件的偏心受压试验,研究锈蚀对H型钢构件偏压承载能力的影响,并为工程师提供锈蚀H型钢构件偏心受压承载能力的试验数据。试验采用5根锈蚀H型钢,2根未锈蚀构件作为对比试验,分别对受拉翼缘、受压翼缘和腹板的锈蚀对H型钢构件偏心受压承载能力的影响进行了详细探究,得出翼缘的锈蚀对钢构件偏压承载能力的影响较腹板显著,其中受压翼缘比受拉翼缘影响更甚。锈蚀对钢材力学性能的影响也在文中进行了试验研究,结果表明:钢材的锈蚀对其屈服强度和极限强度无显著影响,但显著影响钢材塑性性能。

This paper is aimed at experimental study of the effect of corrosion on the bearing performance of H-type steel member subjected to eccentric compression and providing experimental data for engineers. In experiments, 5 H-type corroded steel members were adopted, 2 H-type no rusted steel members were adopted as contrast. The effect of corrosion appeared at tension flange, compression flange and web respectively on the bearing performance of corroded H-type steel member subjected to eccentric compression was experimentally detailed explored. Results show that the corrosion at flange has marked effect on bearing performance of corroded steel H-type steel member subjected to eccentric compression, among which, effect than that of corrosion at tension flange. The corrosion at compression flange has more obvious effect of corrosion on steel material performance is also experimentally studied.
