在侧向荷载作用下,考虑填充板和框架杆件之间的相互作用,研究了钢板剪力墙双体系的非线性性能。对多组钢板剪力墙试件进行数值分析,研究填充板对框架性能的影响,评估其抵抗侧向力的有效度。结果表明:按规范设计的钢板剪力墙具有理想的屈服顺序,填充板首先进入塑性。这说明:填充板在加载初期非常有效,转角可达到1%,承担了大部分层间剪力。然而,一旦填充板中屈服区域继续发展,它们将逐渐失效;当屈服区域延伸至墙体,附加荷载将基本上由框架杆件承担。
Under the action of lateral load, considering the interaction between the filler plate and the frame member, the nonlinear behavior of the shear-wall double-wall system is studied. Several groups of steel shear wall specimens were numerically analyzed to study the effect of the filler plate on the performance of the frame and to evaluate its effectiveness against lateral forces. The results show that the designed shear wall has the ideal yield order, and the filler plate first enters the plasticity. This shows that the filler plate is very effective in the early loading, the corner can reach 1%, assuming most of the interlayer shear. However, once the yield zone in the panel continues to develop, they will gradually fail; when the yield zone extends to the wall, the additional load will be substantially borne by the frame members.
