摘要
为了给钢板剪力墙在实际工程中的应用提供理论支持,在试验研究的基础上,通过ANSYS模拟了薄钢板、十字加劲及开缝钢板剪力墙在低周往复荷载作用下的抗震性能,并与试验数据进行了对比,分析了滞回曲线、骨架曲线、内填板应力及变形等指标。结果表明:有限元分析与试验数据吻合较好,屈服荷载最大误差为10.9%,峰值荷载最大误差仅为1.4%;加劲肋使得内填板应力在小区格范围内发展更充分,但加载后期,加劲肋失效,对内填板面外约束作用微弱;柱脚和梁柱节点以下部位发生局部屈曲,导致整个结构失效。
In order to provide theory support for the use of steel plate shear walls in actual engineering,the seismic performance of the thin steel plate shear wall,the cross stiffener steel plate shear wall and the steel plate shear wall with slits,based on experiments,was simulated under the low cycle reciprocating loading via ANSYS and compared with the test data.The hysteresis curve,skeleton curve,the stress and deformation of infill plate were analyzed.The results indicate that the finite element model data agrees well with the experimental ones.The maximum error of yield load is 10.9%,and that of peak load is only 1.4%.The stress of infill plates gets full development within dividers,while the disabled cross stiffener just gives a weak restraint on the out plane deformation of an infill plate in the later loading period.The local instability below the beam-column joints and column base lead to the failure of the whole structure.
