| 摘 要： | TLD作为一种有效的被动耗能减震控制方法,其减震规律及其分析设计方法一直较受关注。以往的研究较多依赖于试验,并在试验的基础上发展了简化分析方法。但由于模型受限于有限的试验结果,其应用具有一定的局限性。近年来,随着计算机技术的发展,开展考虑流固耦合的TLD数值模拟分析研究成为可能。首先采用流固耦合分析方法对设置屋顶水箱TLD控制的高层框架结构进行地震反应分析,并与已有试验规律及简化方法进行了对比验证;初步探讨了流固耦合问题的计算及建模,并对其进行了验证,实现了考虑流固耦合的TLD数值模拟,总结了高层框架结构的减震规律;并对太原钢铁集团150t不锈钢炼钢主厂房进行了TLD减震效应分析和设计。结果表明,采用考虑流固耦合的FSI分析方法符合试验规律,物理意义更加明确、直观,用于TLD减震效应分析将是一种趋势,也是对现有分析方法的有益补充。

| Abstract: | TLD is an efficient passive control device for vibration energy-dissipating,whose rule and analysis design method have received much attention.Actually,the previous researches were mainly relied on tests and have got fruitful achievements in the damping of vibration rule.Though the simplified analysis method of damping of vibration effect has also been developed based on those tests,its application has been greatly limited due to the rough models.Recently,with the development of computer technology,it is li... |
