摘要

摘要: 两边连接钢板剪力墙侧边由于受压屈曲产生较大变形,削弱其承载力和耗能能力。在两侧边采取加劲措施可以增强两侧边的稳定性,并在一定程度上提高承载能力和耗能能力。采用ANSYS有限元软件对侧边理想加劲的两边连接钢板剪力墙进行滞回分析,研究在理想加劲情况下,加劲肋对两边连接钢板剪力墙受力模式、承载能力和耗能能力的影响。分析结果表明,理想加劲情况下,拉力带较易产生,也因此提高了承载能力和耗能能力。随高厚比增大,加劲肋的影响相对增大;而随跨高比增大,加劲肋的影响趋于减小。

Abstract: When lateral load is applied on steel plate shear wall connected with frame beams,the buckling of plate corner appears,which causes the lost of bearing capacity and energy dissipation ability.Stiffeners connected on two free sides not only prevent corner plate from early buckling but also increase the bearing capacity and energy dissipation ability.Finite element software ANSYS is used to analyze the effect when the two free sides are well strengthened.The results show that the strengthened sides make the tension field easy to form and this leads to the increasing of aseismatic performance of steel plate shear wall with two-side connections.With the increase of height-to-thickness ratio,the effect of stiffeners increases;when span-to-height ratio increases,the effect of stiffeners decrease.
