工字形加劲肋带缝钢板剪力墙具有延性好、耗能能力强等优点,可有效避免钢板剪力墙对框架柱产生附加荷载而导致相邻框架柱过早发生破坏。对带缝钢板剪力墙以及工字形加劲肋带缝钢板剪力墙的弹性屈曲特征、滞回性能、应力、应变分布规律等力学性能进行了对比分析。结果表明,工字形加劲肋带缝钢板剪力墙的屈曲临界荷载为无加劲肋带缝钢板剪力墙屈曲临界荷载的2.15倍;工字形带缝钢板剪力墙的滞回曲线稳定且饱满,强化阶段被充分发挥,其抗侧承载力、延性及耗能能力显著提高;工字形加劲肋带缝钢板剪力墙用钢量系数比无加劲肋带缝钢板剪力墙降低了16%。 I-shaped stiffened strip steel plate shear wall with good ductility, energy consumption and other advantages, which can effectively avoid the steel sheet shear wall on the frame column additional load caused by the adjacent frame column premature failure. The mechanical buckling characteristics such as elastic buckling, hysteretic behavior, stress and strain distribution of the shear wall with slotted steel plates and I-shaped stiffened steel plates with slit are compared and analyzed. The results show that the buckling critical load of I-shaped stiffened steel plate shear wall is 2.15 times of the buckling critical load of stiffened steel plate shear wall without stiffeners. The hysteretic curve of I-shaped steel plate shear wall is stable and full, The reinforcement stage is fully utilized, and its anti-side bearing capacity, ductility and energy dissipation capacity are significantly increased. The steel coefficient of I-shaped stiffened steel plate shear wall is reduced by 16% compared with the stiffened steel plate shear wall.
