| 中文摘要 | 本文基于钢结构设计规范GB50017-2003,利用三柱子框架模型,考虑了连接的非线性弯矩-转角关系和楼板组合效应的影响,推导了无侧移半刚性连接组合框架柱的有效长度系数方程式,同时考虑了梁端和柱远端不同约束情况对有效长度系数的影响。另外,分析了GB50017规范附录D表D-1求解的精确性。研究表明,当柱远端刚接时,推导的方程式类似于GB50017规范附录D表D-1给出的无侧移刚接框架柱的有效长度系数计算公式;对于三柱子框架模型,当柱远端铰接时,用GB50017规范附录D表D-1得到的有效长度系数设计柱是不安全的,但最大误差只有11%。; Based on code for design of steel structures GB50017-2003 and using the three column subassemblage model,a governing equation for determining the effective length factor (μ-factor) of columns for non-sway semi-rigid composite frames was derived considering the effects of the nonlinear moment rotation characteristics of beam-to-column connections and composite action of slab.The effects of various beam end conditions and column far end conditions on μ-factor were considered.Furthermore,the accuracies of GB50017 specified appendix D table D-1 solution were assessed.The research results show: when the far end of column is rigidly connected with next column,the derived equation degenerates to an equation for determining the μ-factor of columns in non-sway rigid frames;using GB50017 specified appendix D table D-1,the μ-factor in the subassemblage models with pinned pin boundaries provide an unconservative design of columns,but the maximum error is only 11%.; 国家杰出青年科学基金资助项目(50225825) |
