摘要:
基于《钢结构设计规范》(GB 50017—2003),利用三柱子框架模型推导了无侧移半刚性连接箱式模块化框架柱计算长度系数方程,给出了基于分析假定的柱计算长度系数理论解,提出了针对无侧移半刚性连接箱式模块化框架柱计算长度系数的实用计算公式;通过对比理论计算结果和有限元分析结果,验证了实用计算公式的精确性与适用性;研究了无侧移半刚性连接箱式模块化框架柱计算长度系数的各影响因素。结果表明:柱计算长度系数除了受到半刚性节点刚度变化的影响外,还受到上下相邻模块框架梁对框架柱约束系数比值的影响;当上下相邻模块框架梁对框架柱约束系数的比值均为1时,柱计算长度系数不随节点刚度变化而变化。
Abstract:
Based on Code for Design of Steel Structures(GB 50017—2003) and using the three column subassemblage model, a governing equation for determining the effective length factor of column for non-sway modular frame with semi-rigid connection was derived. Furthermore, the theoretical solution to evaluate the corresponding column effective length factor was proposed. The effectiveness and accuracy of the simplified calculation formulas were illustrated through comparing the theoretical calculation results and finite element analysis results. At last, influencing factors of effective length factor of column for non-sway modular frame with semi-rigid connection were investigated. The results show that the effective length factor is affected not only by the connection stiffness but also by the ratio of modified relative stiffness factor. When the ratio of modified relative stiffness factor is 1, the effective length factor doesn’t change with connection stiffness.
