【摘要】 以一榀半刚性钢框架模型为例,在某些假定条件下,导出了其在水平荷载作用下的弹性侧移公式,并与刚性钢框架在水平荷载作用下的侧移公式进行比较,引入框架梁名义线刚度的概念,提出了在半刚性钢框架设计中采用框架梁名义线刚度来考虑连接初始刚度对框架水平侧移的影响。更多还原

【Abstract】 The paper derived the simplified calculation of the horizontal displacement of the semi-rigid connections steel frame at some assumed connections through a semi-rigid steel frame.The paper inducts the concept of nominal linear-stiffness by means of the comparison of the rigid and semi-rigid connection steel frames under the horizontal load and put forward that it should adopt the nominal line-stiffness to consider the influence of the initial stiffness to the horizontal displacement of the semi-rigid connection steel frames.更多还原
