摘要
对 30个同类型配筋砌块砌体的试验 ,对其单调横向荷载 位移关系曲线进行修正 ,从而提出了用于代表配筋砌块墙体动力特性的滞回骨架曲线·同时表明 ,竖向荷载的大小对荷载 位移曲线及滞回骨架曲线有一定影响·试验结果表明 ,该骨架曲线正确合理 ,可用于配筋砌块砌体的动力分析中·并经低周循环和模拟地震反应的荷载试验验证 ,符合程度较好·
A method to modify lateral load displacement relationship is established by a simple monotonic test to represent the skeleton hysteresis curve of an arbitrary dynamic response of a reinforced masonry wall according to the results of 30 equal reinforced masonry wall. It is shown that the level of vertical load affacts the shape of both the lateral load displacement curve and the hysteresis curve. It is also shown that the skeleton hysteresis curve is correct and can be used in the dynamic nanalysis of small size concrete hollow block reinforced masonry wall.
