摘要: 首先分析波浪腹板阶形柱计算长度系数计算的相关问题,理论推导过程中考虑剪切变形对其稳定性的影响,得到考虑剪切变形时计算长度系数计算的精确公式,并与不考虑剪切变形的计算公式(GB500172003《钢结构设计规范》)以及有限元计算结果进行对比,从而得出了CECS 290:2011《波浪腹板钢结构技术规程》中对于波浪腹板阶形柱计算长度系数计算的取值原则。其次,对波浪腹板阶形柱在侧向荷载作用下的变形进行分析,得到计算波浪腹板阶形柱侧向变形的计算公式。另外,根据波浪腹板阶形柱的特殊性,对波浪腹板阶形柱连接处的肩梁构造与计算方法进行阐述。Abstract: The effect of shear deformation in singly-stepped sinusoidal corrugated web columns on the effective lengthfactors is analyzed, and theoretically derived formulation was presented firstly. Compared with approximately TheCode for Design of Steel Structures ( GB 5001 7 2003 ) and the FEA results, it was concluded that the verification ofglobal stability in the singly-stepped sinusoidal corrugated web columns is proposed by combing the effective lengthfactors given by GB 5001 7 2003 with the design formula from Technical Specification for Sinusoidal Web SteelStructures ( CECS 290:201 1 ) which reflects the effect of shear deformation of corrugated web. And the formula forcalculating the lateral deformation of singly-stepped sinusoidal corrugated web columns was given. Finally, thestructural construction details and design of shoulder-beam of singly-stepped column were introduced.
