|
摘要
随机振动对建筑工程的破坏严重,随机性振动的破坏程度很难量化,抗震参数测试较为困难,给相关建筑工程的稳定性带来极大威胁。研究随机振动下建筑工程抗震测试方法。结合随机振动理论,获取随机振动下建筑工程功率谱密度函数,分析建筑随机振动下响应功率;依照响应功率谱密度,分析随机振动下建筑工程各阶谱矩、均方差值等抗震性能概率特征,检测建筑工程在随机地震振动下的抗震性。以我国某省建筑工程为实验对象,验证测试方法的抗震参数检测性能,结果表明:提出的方法在随机振动作用下,能有效获取建筑工程的功率谱密度,和振动波动情况,且检测失效概率与可靠度与实际情况更为相近。
Random vibration causes serious damage to building engineering, and the damage degree of random vibration is difficult to quantify. It is difficult to test seismic parameters, which poses a great threat to the stability of related building engineering. The seismic test method of building engineering under random vibration is studied. Based on the theory of random vibration, the power spectral density function of building engineering under random vibration is obtained, and the response power under random vibration is analyzed. According to the response power spectral density, the probability characteristics of seismic performance such as spectral moments and mean square deviation of building engineering under random vibration are analyzed, and the seismic performance of building engineering under random seismic vibration is tested. The test results show that the proposed method can effectively obtain the power spectral density and vibration fluctuation of a building project under random vibration, and the detection failure probability and reliability are more similar to the actual situation..
