【摘要】 在研制一套具有竖向耗能能力的抗倾覆装置过程中,针对该装置对阻尼器的要求,设计了两种铅阻尼器,铅剪切阻尼器和钢铅组合耗能器。根据实验得出的两种铅阻尼器的滞回曲线的基础上,简化滞回规则,并通过算例分析,给出控制效果分析。分析表明,两种阻尼器对结构的竖向震动起到了一定的控制效果,适合工程应用。更多还原

【Abstract】 In process of research on resisting-overturn equipment with energy dissipation in vertical, two kinds of lead dampers are designed in order to meet the requirement of equipment, one is the lead shear damper, and the other is the mixed steel lead damper. According to the hysteretic curves obtained form MTS tests, hysteretic characteristics of the dampers are summed up. A structure is analyzed by the program, which makes use of the hysteretic characteristics of the dampers for ensuring the control effet. The results show that the two kinds of dampers have good control effect in vertical direction. They are useful in engineering.更多还原
