摘　　要：针对两边连接侧边加劲钢板剪力墙,设计了1/3缩尺模型试件,通过低周反复加载对其滞回性能进行了试验研究。采用有限元软件ABAQUS建立了该试件的有限元分析模型,对其滞回性能进行了数值模拟,并将分析结果与试验结果进行了对比,验证了有限元模型的可靠性;利用该有限元分析模型重点考察了试件高宽比、高厚比及加劲肋厚度对两边连接侧边加劲钢板剪力墙滞回性能的影响规律。研究表明:两边连接侧边加劲钢板剪力墙滞回曲线其饱满程度随高宽比的降低而下降,随高厚比的降低而提高,与加劲肋厚度的变化无关;单位累计耗能随高宽比的降低、高厚比的降低以及加劲肋厚度的增大有不同程度的提高,其中高厚比的影响最为显著;极限平均剪应力的变化规律与单位累计耗能一致,并接近剪切屈服强度。该研究为钢板剪力墙的设计应用提供了依据。One specimen was designed in the light of a steel plate shear wall with two-side connections and side stiffened.The specimen was tested under cyclic loading at a scale ratio of 1/3 to investigate its hysteretic behavior.A finite element analysis model of this specimen was established by using the finite element software ABAQUS to simulate its hysteretic behaviors.Finite element results and experimental results were made a comparison to verify the reliability of the finite element model.The influences of aspect ratio,height-thickness ratio,and thickness of the stiffener on hysteretic behaviors of the steel plate shear wall with two-side connections and side stiffened were investigated by using the verified finite element model.Research results show that the full degree of hysteresis curve,which is not related to the variation of the thickness of the stiffeners,decreases with the decrease of aspect ratio and increases with the decrease of the height-thickness ratio.Cumulative energy consumption per unit increases with the decrease of the aspect ratio,with the decrease of height-thickness ratio and with the increase of the thickness of the stiffeners,the influence of height-thickness ratio is the most significant among them.The change regulations of maximum average shear stress is in accord with cumulative energy consumption per unit and maximum average shear stress is close to the shear yield strength gradually.The above research provides a basis for the design and application of a steel plate shear wall.
