摘要
采用ANSYS有限元程序对两边连接钢板剪力墙进行数值模拟分析。通过对单跨多层两边连接钢板剪力墙在单向荷载作用下的受力特点进行分析,提出、建立并验证等效简化计算模型;研究两边连接钢板剪力墙的受力机理和破坏模式,分析钢板高厚比λ和跨高比β对两边连接钢板剪力墙抗剪静力性能的影响,探讨框架梁的受力特点。研究结果表明:高厚比λ和跨高比β是影响两边连接钢板剪力墙抗剪静力性能的主要因素;两边连接钢板剪力墙与四边连接钢板剪力墙剪力传递方式是不同的;两边连接钢板剪力墙的钢板不对框架柱产生作用力和附加弯矩,更符合"强柱弱梁"的抗震设计理念;当采用高厚比较小的剪力墙时,两边连接钢板剪力墙对框架梁抗剪要求增大,须采取适当的构造措施,以保证框架梁不先于剪力墙破坏。
The numerical simulation and analysis of shear resistance behavior of two-side connected steel-plate shear wall （SPSW） was carried out by the finite element software ANSYS. In order to investigate the behavior of two-side connected SPSW, a simplified analysis model is brought forward and verified by analyzing the stress characters of a single-span multilevel model under monotonic loads. The forced mechanism and failure mode are investigated. The mechanical behavior of the beams is also discussed in details. It is found that depth-thickness ratio λ and span-depth ratio β are the key parameters which influence the shear resistance behavior of two-side connected SPSW; the transfer mode of the horizontal loads is different between two-side connected SPSW and four-side connected SPSW; two-side connected SPSW has no additional moments in columns, which fit the aseismatic principle of ＂strong column and weak beam＂ better; structural measures of the beam connected with the steel plate is demanded when depth-thickness ratio is big , it will guarantee that the damage on the beam occurs latter than the steel plate.
