转运站结构的动力分析与振动控制

Dynamic analysis and vibration control of transfer station structure

为进一步探明转运站结构的实际工作状态,本文对某通廊转运站建立不考虑通廊水平支撑作用和考虑通廊水平支撑作用两种模型分别进行了动力分析,并现场进行了振动测试,通过试验测试和动力分析结果的验证对比和讨论,得出了较为合理的分析模型。针对振动问题对建筑物结构、机器设备、人体等三个主要影响的方面,结合现有振动容许限值标准及对结构的动力分析和振动测试结果,对本通廊转运站的现状进行了全面评估,对存在的问题提出了可行的改良化建议。

In order to further prove up the actual working status of transfer station structure,dynamic analysis for two models of a traverse transfer station was made respectively, one model considers horizontal supporting function of traverse but the other doesn＇ t,and vibration test was made at site. Through comparison and discussion of test result and dynamic analysis result, a rational analysis-model was obtained. Three aspects such as structure, equipment and human body are mostly influenced by the vibration problems in a building, in combination with existing standards of allowable value of vibration and testing value and analysis value, the present condition of the transfer station was wholly evaluated, and some feasible improvement suggestions for the existed problems were proposed.
