摘要

摘要: 通过与Q345-B热轧H型钢悬臂梁的对比,研究高强热轧H型钢悬臂梁在低周反复荷载作用下的受力性能。对试件的受力变形形态、破坏模态进行研究,得到试件的滞回曲线、骨架曲线、承载能力、延性性能和能量耗散系数等。试验结果表明,高强热轧H型钢具有较高的承载能力,较好的延性和耗能能力。用理论公式计算试件的屈服荷载和刚度,用SAP 2000模拟试件的滞回性能,两者结果吻合良好。

Abstract: The mechanical performance of high-strength hot-rolled H-cantilever beam under low cyclic loading by comparative study with Q345-B hot-rolled H-beam was introduced.The deformation behavior and failure mode were discussed,with which the hysteretic loops,skeleton curves,bearing capacity,ductility and energy dissipation coefficient were obtained.The experimental results showed that high-strength hot-rolled H-beam possed large bearing capacity,good ductility and energy dissipation capability.Both the yield strength and initiated stiffness calculated with theoretical formula,and the hysteretic behavior simulated with SAP 2000 were in accordance well with experimental results.
