Abstract:

针对当前砌体填充墙框架结构数值模拟中缺乏简单有效的填充墙建模方法,缺少对填充墙-框架刚性连接和柔性连接的考虑等问题,提出了基于等效弹簧单元的填充墙框架结构有限元分析方法。首先,将填充墙框架结构拆分成空框架和等效约束填充墙,其中等效约束填充墙综合考虑了填充墙对框架柱的侧向约束,以及主体框架对填充墙的闭合约束;其次,在粉煤灰空心砌块墙体及砌体填充墙框架结构水平往复荷载试验的基础上,分析了墙-框刚性连接与柔性连接情况下等效约束填充墙的力学性能,提出了填充墙的滞回曲线模型及等效弹簧有限元分析模型;最后,分别进行了刚性连接和柔性连接填充墙框架结构水平单调荷载作用下的有限元试验拟合。计算结果表明等效弹簧单元能够有效模拟等效约束填充墙的工作,且建模方式简便易行,特别适用于砌体填充墙框架整体结构的数值模拟分析。
