Furthermore , based upon the explicit relationship between critical loads of frames and bracing stiffness , the expression of critical bracing stiffness at which the frames will buckle in a non - sway mode is also proposed . the relationship between the critical load of frames and the stiffness of flexural - typed bracings was extended to more general cases where bracing systems are of flexural - and - shear - type . the expression of the critical stiffness for this type of bracings was also suggested
在已有弯曲型支撑研究结果的基础上，把框架?弯曲型支撑双重结构体系中支撑刚度与框架临界荷载的关系式推广到了框架?弯剪型支撑的情况，得到了弯剪型支撑的临界刚度计算式和非完全支撑(弱支撑)框架临界荷载的计算公式。
