摘要:
对于平板柱脚轴心受压柱,《钢结构设计规范》将柱脚当作铰接看待,不考虑其转动约束作用.研究表明,钢结构平板柱脚具有较大的转动刚度.为研究钢结构平板柱脚对钢柱的转动约束作用,对10个采用平板柱脚的H型钢柱进行了试验研究,分析了锚栓数量、底板厚度及柱子长细比等因素对柱脚转动约束性能的影响,得到了柱脚弯矩-转角曲线和柱脚转动刚度.提出了平板柱脚转动刚度计算公式,得出了柱子计算长度系数的近似计算公式
Abstract:
In the Code for Design of Steel Structures, the plated column base of steel column is considered as ideal hinged constraint, but the rotational restraint of the column base is not. The research results show that the plated column base of steel column has considerable rotational constraint. To research the rotational constraint of column base, experimental research was conducted for 10H-section columns with plated column bases of steel column. The moment-rotation curves of the column bases, the rotational rigidity of the plated column bases were obtained. The formulas of the rotational rigidity of the plated column base of steel column were proposed according to the experimental results, and the approximate formula of the effective length factor was obtained
