摘　　要：为探究胶合木框架结构抗侧刚度的影响因素,推导了三层半刚接结构框架的抗侧刚度的计算公式,确定了框架抗侧刚度与节点刚度、柱线刚度和梁线刚度的关系,并对采用不同的柱截面尺寸和节点刚度的框架结构进行了有限元模拟。结果表明:节点刚度与柱线刚度是影响结构抗侧刚度的主要因素,抗侧刚度随着节点刚度和柱线刚度的增加而增大;柱截面尺寸较小时,节点刚度对结构抗侧刚度的影响显著,是提高结构抗侧刚度的有效手段;节点刚度较小时,柱截面尺寸对结构抗侧刚度的影响也较明显,但不够经济。该研究成果可为胶合木结构设计提供一定参考。In order to explore the influencing factors of the lateral stiffness of glued timber frame structure, the calculation formula of the lateral stiffness of the three-story semi-rigid frame structure was deduced, the relationship between the lateral stiffness of the frame and the joint stiffness, column line stiffness and beam line stiffness was determined.The frame structure with different column cross section and joint stiffness was simulated by finite element method.The results show that the joint stiffness and column line stiffness are the main factors affecting the lateral stiffness of the structure, and the lateral stiffness increases with the increase of joint stiffness and column line stiffness.When the column cross section is small, the joint stiffness has a significant impact on the lateral stiffness of the structure, which is an effective method to improve the structural lateral stiffness.When the joint stiffness is small, the influence of column cross section on the lateral stiffness of the structure is also obvious, but it is not economical.The research results can provide some reference for the design of glued timber structure.
