| 摘 要： | 为了更好地研究地震烈度对结构破坏的影响及震害规律,运用LS-DYNA软件对Ⅷ度区和Ⅸ度区的底层框架砌体结构进行了由损伤至倒塌破坏的全过程的模拟,研究结果表明:在罕遇地震烈度情况下,Ⅸ度区的结构要比Ⅷ度区的结构出现破坏的时间早,并且要比Ⅷ度区的破坏严重。对比时程分析的结果,位移要滞后于加速度,但地震过程中结构的动力反应趋势大致相同。该成果反应了不同烈度下结构的地震反应特征,仿真结果和真实倒塌过程吻合较好。

| Abstract: | In order to research the impact of damage and the rule of the earthquake damage by seismic intensity,the whole process from the damage to the collapse of masonry structure with bottom frame in 8 degree and 9 degree is simulated using LS-DYNA software in this paper.The results show that the structure appears damage in the 9 degree is earlier than in the 8 degree in the case of rare intensity,and more serious than in 8 degree.Compare the results of time-history analysis in different seismic intensity,displace... |
