在钢板剪力墙结构边框柱的柔度系数ωt的推导过程中未考虑稳定理论,最小惯性矩要求仅能控制边柱平面内的稳定性,而平面外的稳定性很难得到保证,并且推导未考虑结构自重等传递的竖向荷载对框架的不利作用。本文结合等效负刚度和拉力场机制份额的概念,研究了同时考虑轴压和剪切作用下结构边框柱平面内的柱柔度限值要求。同时结合稳定等效的方法给出了钢板剪力墙结构边框柱平面内、平面外稳定性的校核方法。研究表明,当考虑框架柱承担竖向荷载时,建议框架柱轴压比控制在0.3以下,柱柔度限值小于等于2.1,框架柱平面内的稳定性可以得到保证,但平面外的稳定性要重新校核。 Stability theory has not been considered the derivation process of flexibility coefficient ωt of vertical boundary elements in Steel Plate Shear Walls, the minimum inertia requirements can only control the stability of out of plane of vertical boundary elements in steel plate shear walls, and the adverse effects of the vertical loads on the frame has not been considered. Combining the concepts of equivalent negative stiffness and tension-field proportion to obtain the limitation of column flexibility under the axial compression and shear loading. Under the vertical loading, axial compression ratio should be controlled under 0.3. By using energy method, we obtain the stability analysis method of steel plate shear walls. The results show that when the limitation of column flexibility is under 2.1, the stability in plane could be guaranteed, but out-of-plane should be reconsidered
