摘要
通过对混凝土多孔砖砌体房屋结构的抗震可靠性研究,提出了基于概率地震烈度所对应的地面运动加速度峰值分布的可靠度计算公式和采用将各烈度地震对应的峰值加速度概率进行离散化处理的方法,基于作者早期的混凝土多孔砖墙片试验的结果推导出该结构水平最大位移和累积能量耗损的双参数破坏准则,分析了混凝土多孔砖砌体房屋结构在不同地震设防区的抗震安全性能及其影响因素。
The seismic reliability of concrete perforated brick masonry structure is studied. Based on the peak acceleration distribution related with probability of earthquake intensity, the formula of the structure seismic reliability in the earthquake zone is proposed, and a discrete method is obtained. By considering the most horizontal displacement and the cumulative energy damage, a new double-parameters criterion based on the early experiment is derived. The seismic safety performance of concrete perforated brick masonry structure in the different earthquake intensity fortification area and its influence factor are analyzed.
