摘要
提出多高层钢框架-支撑体系在水平荷载作用下的内力和变形计算应依支撑的变形型式的不同而采取不同的计算方法.当支撑的变形型式为剪切型时用D值法,当支撑变形型式为弯曲型时用与框架协同工作的位移法.重点就剪切型支撑计算中如何考虑弯曲变形的影响,弯曲型支撑如何考虑剪切变形的影响以及框架因整体弯曲产生的柱轴向变形的影响作了进一步分析,从而提出在结构分析中的若干改进措施.
Under different deformation mode, different analysis methods should be adopted for multi-high steel frame-brace system under lateral loads. On case of shearing deformation mode, D value method be reasonable; while bending deformation mode, compatible displacement method be adopted. Emphases are given to bending deformation under shearing brace, and shearing deformation under bending brace, even the effects of column axial deformation under global bending. Some comments on the structural analysis are proposed.
