井字形加劲部分连接钢板剪力墙的性能分析

ANALYSIS OF THE PERFORMANCES OF WELL-SHAPED STIFFENED PARTIALLY CONNECTED STEEL PLATE SHEAR WALL

井字形加劲部分连接钢板剪力墙是对部分连接钢板剪力墙进行了加劲改进,在保持其优势的同时,改善其性能,是一种新型钢板剪力墙结构体系。井字形加劲后,结构的传力机制变得更为复杂,采用有限元软件ABAQUS进行模拟计算,探究了井字形加劲部分连接钢板剪力墙在水平低周往复荷载作用下的滞回性能,分析了加劲位置、肋板高厚比、加劲刚度比和钢板高厚比等相关参数对结构整体性能的影响。

Well-shaped stiffened partially connected steel plate shear wall,which installs stiffeners on it,is a modification of partially connected steel plate shear wall.This novel steel plate shear wall keeps the advantages of the original one,and improves the performances at the same time.After the well-shaped stiffening,the force-transferring mechanism becomes more complex.Therefore,the finite element software ABAQUS was used to investigate the hysteretic behavior of well-shaped stiffened partially connected steel plate shear wall under quasi-static load,analyzing how the position,the height-thickness ratio and the stiffeness ratio of stiffener and the height-thickness ratio of steel plate aftect the performances of the wall system.
