推导了斜交网格筒结构子模块的侧向刚度、剪切转角和弯曲转角的简化计算式.通过结构腹板角部斜柱的轴向应变与子模块变形转角之间的关系,建立了子模块变形转角的计算方法,并通过SAP2000软件进行了验证.提出了通过斜交网格筒结构各子模块的变形转角,来控制其在弹性阶段时的侧向刚度及变形能力.结果得出:剪切刚度和弯曲刚度均随着斜柱角度的增大而减小;在相同的侧向荷载作用下,随着斜柱角度的增大,剪切转角与弯曲转角的比值逐渐增大;变形转角受斜柱角度变化的影响比较明显,建议根据结构具体的几何参数,不同斜柱角度的结构应采取不同的弹性位移角限值.
The simplified formulas of lateral stiffness, shear angle and bending angle of the skewed grid structure sub-module are deduced.The relationship between the axial strain and the deformation angle of the submodule at the corner of the structural web is established Module deformation angle is calculated and verified by SAP2000 software.It is proposed to control the lateral stiffness and deformation capacity of the submodules in a skewed grid structure by controlling the deformation angle of each submodule in the skewed grid structure. Both shear stiffness and bending stiffness decrease with the angle of inclined column increasing. With the increase of inclined column angle, the ratio of shear angle to bending angle increases with the same lateral load. The deformation angle is affected by the change of the angle of the inclined column. It is suggested that different elastic displacement angle limits should be adopted according to the specific geometric parameters of the structure.
