【摘要】 本文根据砖烟囱的构造特点和材料性能,采用半有限元-半解析法对砖烟囱在多向地震动输入时的脆性破坏过程进行了模拟计算。通过分析不同高度的砖烟囱在不同地震动输入时的破坏特征,探讨了砖烟囱在多向地震力作用下的破坏机理和一般规律。更多还原

【Abstract】 In this paper, considering the constructional characteristic of brick chimneys and the feature of the material, a combined procedure of the finite element and analytical methods is employed to simulate the brittle failure process of brick chimneys suffering multi-dimensional ground motions.By analysing the failure behavior of chimneys with different heights under earthquake inputs, the mechanism of the failure of brick chimneys under earthquakes is studied.更多还原
