摘要:
利用OpenSEES建立木框架-剪力墙的有限元模型,选取OpenSEES中的Pinching4材料本构模型来模拟钉连接的非线性、强度退化、刚度退化和捏拢现象,模拟结果与试验结果吻合较好,论证了Pinching4材料模型可以同时适用于“单剪”和“双剪”两种形式的钉连接。通过在OpenSEES中建立木框架-剪力墙的参数化模型,分析钉间距和高宽比对木框架-剪力墙承载能力的影响,发现随着钉间距的减小,抗侧性能显著提高; 高宽比对墙体抗侧性能影响不大; 面板边缘钉连接对墙体承载力的影响更大。
Abstract:
A Pinching4 material constitutive model was built by finite element method with OpenSEES for timber frame-shear wall for high nonlinearity, strength degradation, stiffness degradation and pinching. The simulation results were in a good agreement with the existing experiments, which illustrated that Pinching4 model was applicable to both unidirectional shear and bi-directional shear. The effects of nail spacing and aspect ratio on the timber frame-shear wall by building parametric model from OpenSEES were obtained. It was found that with the decrease of the nail spacing, the lateral performance was significantly improved, while the aspect ratio had little effect on the lateral performance of the wall.
