工程结构环境振动影响评价指标研究
|
摘要
频繁的环境振动会引起工程结构疲劳损伤和破坏,但目前我国尚缺乏相关技术标准。本文对由打桩施工和地铁运行引起的地面水平振动,运用有限元法分析了一个6层水平剪切型工程结构各层的最大层间剪力及其与地面水平振动最大加速度、速度和位移之间的相关性。计算结果表明,由振动引起的结构最大层间剪力与地面水平振动最大速度的相关性相对最好,加速度的稍差,而与位移的相关性最差。本文研究内容和结果对建立和完善我国工程结构环境振动影响评价技术标准,具有一定的实用参考价值。
In this paper,finite element analysis method is used to calculate the maximum inter-story shear force of a frame structure.Then,the correlation between that with the maximum acceleration,velocity and displacement of ground horizontal vibrations are analyzed respectively with the result that the inter-story shear force has the best relativity with ground velocity and the worst with ground displacement.This study has a certain reference value for establishing and improving evaluation criteria for engineering structure under environmental vibrations in China.
