为了研究加劲肋和防屈曲措施对变缝钢板剪力墙受力性能的影响,应用有限元软件ADINA建立12 mm厚的变缝钢板剪力墙模型并分别在模型两侧布置加劲肋和在模型上施加面外防屈曲措施,模拟并分析两侧加劲肋和面外防屈曲措施对变缝钢板剪力墙受力性能的影响。分析结果表明:两侧加劲肋可以提高模型的受力性能,延迟模型发生过早的捏拢现象,端部出现了应力集中现象;面外防屈曲措施的施加既可以明显改善模型的受力性能,又可以使模型在加载全程都具有良好的耗能能力,应力、应变区域发生了相应的减小。
In order to study the effect of stiffeners and buckling-proofing measures on the mechanical behavior of steel plate shear walls, a finite element software ADINA was used to establish a 12 mm-thick steel plate shear wall model with stiffeners on both sides of the model. On the outer surface of the anti-buckling measures to simulate and analyze both sides of the stiffener and out of plane buckling measures on the mechanical properties of the steel plate shear wall. The analysis results show that the stiffeners on both sides can improve the mechanical performance of the model, delay the premature pinch phenomenon and the stress concentration on the end of the model, and the application of out-of-plane buckling restraint can not only significantly improve the force performance of the model , But also can make the model have good energy dissipation capacity in the whole process of loading, and the stress and strain areas have correspondingly decreased.
