H型钢阻尼器实验与数值仿真
|
摘要
吸收国内外软钢阻尼器的研究成果,通过实验与数值仿真对H型钢阻尼器的滞回性能和恢复力模型进行了研究,表明H型钢阻尼器采用弹塑性材料模型在循环荷载作用下具有良好的耗能性能。通过分析说明构造简单,屈服强度大的H型钢阻尼器能应用于实践,在相同的耗能能力下比其他软钢阻尼器生产成本更低。
According to the all abroad study results,the restoring force model of the H-shape steel damper was studied through tests and numerical analysis,proving that it has a good hysteresis loop curve between force and displacement under cyclic loading adopting an ideal elastic-plastic model.The analysis also showed that the easily made and the high stress of the H-shape steel damper can be applicable to the practice,and with the same ability of consuming the energy,it can be much cheaper than other steel dampers.
