摘要

摘要: 为研究锈蚀对H型钢梁受弯承载性能的影响，从大气环境锈蚀3年的H型钢构件上分别截取了标准拉伸试件和钢梁试件，开展了锈蚀钢材单调拉伸和锈蚀钢梁受弯性能试验，研究了锈蚀钢材屈服强度、极限强度、延伸率与截面面积损失率之间的关系，揭示了锈蚀钢梁屈服荷载、极限荷载随强轴惯性矩损失率的变化规律，提出了锈蚀H钢梁抗弯承载力计算方法。研究结果表明，随着锈蚀程度不断增大，锈蚀钢材屈服强度、极限强度、钢梁屈服荷载和极限荷载逐渐下降。

Abstract: In order to study the influence of corrosion on the flexural property of H-shaped steel beams, the standard tensile specimens and steel beams were cut off from H-shaped steel members corroded in the atmospheric environment for three years. The monotonic tensile test of corroded steel and bending test of corroded steel beams were conducted. The relations of yield strength, ultimate strength and ductility with section loss ratios of corroded H-shaped steel beams was discussed, and the change low of the yield load and ultimate load of corroded H-shape steel beams with loss rate of strong axis moment of inertia was revealed. The calculation method of flexural capacity of corroded steel beams was proposed. The results showed that with the increase of corrosion degree, the yield strength, ultimate strength, yield strength and ultimate strength of corroded H-shaped steel beams decreased gradually.
