| 摘 要： | 设计制作了内填充榫卯砌块墙体的钢框架,对体系施加低周水平往复荷载。在往复荷载的作用下,在榫卯节点连接处产生了应力集中,榫头的上部边缘发生剪切破坏,使得插孔处混凝土被压碎,最终导致墙体与连接件发生脱离而体系破坏。开裂后,滞回曲线由梭形向弓形、反S形变化,开裂荷载约为极限荷载的48%,大于同类钢框架填充墙体的比值。说明榫卯结构改善了墙体的变形能力,在墙体达到极限荷载后,可保持裂而不倒。体系的能量耗散系数、等效粘滞阻尼比和延性优于普通填充墙体,说明榫卯结构提高了墙体的耗能能力进而提高了抗震能力。

| Abstract: | A steel frame infilled with mortice-tenon wall is designed and made.Reciprocal horizontal loads are applied to the frame-wall system.Stress concentration occurs at the connection of mortice and tenon under the reciprocal loads.The top edge of tenon is cracked by shear force,in which the concrete is crushed.The system failed because the wall broken away from connector.After cracking,hysteretic curve has changed from shuttle shape to arc or reversed S shape.Cracking load is 48 percentage of ultimate load,whic... |
