建筑结构对爆破地震的动力响应特性研究
|
摘要
首先分析了建筑结构的爆破地震安全判据的不足和爆破地震与天然地震的特点,然后详细地分析了爆破参量对爆破地震波反应谱的影响和爆破地震频率对建筑结构破坏的影响,并着重分析了建筑结构对爆破地震波主频率的响应特性和爆破地震波主频率的特性及一般规律,最后提出了今后进行建筑结构对爆破地震的动力响应特性研究和爆破地震作用下建筑结构的安全程度评价研究的建议。
The default of safety criteria for blasting earthquake of building structure is analyzed,and the characteristics of blasting earthquake and natural earthquake are discussed.The influence of blasting parameters on response spectra of blasting seismic wave and the influence blasting vibration frequency on the damage of building structure are analyzed in detail.The characteristics of building structure response to the main vibration frequency of blasting seismic wave,the characteristics of the main vibration frequency of blasting seismic wave and its principle are especially analyzed.The proposals of study on the characteristics of the building structure dynamic response to blasting earthquake and the safety evaluation of building structure under blasting earthquake are presented.
