A design method of frames with pin-ended columns was proposed and its validity was verified by the static or dynamic analyses of braced steel frames with pin-ended columns. Obtained results are as follows:1. Design requirements for the stability of braced steel frames with pin-ended columns are 1) Redundancy, 2) Strength and stiffness of beam, brace and floor, 3) Prevention of story collapse, 4) Limitation of Axial force, 5) Strength deterioration of member.2. If the column at a comer is a rigid-ended column, the behavior of the frame becomes stable.3. The responses of the steel frame with viscous dampers and pin-ended columns are small compared to those of other frames, and are uniformed along the height.

提出了一种销端柱框架的设计方法，并通过销端柱支撑钢框架的静力和动力分析验证了其有效性。得到的结果如下： 1．销端柱支撑钢框架稳定性的设计要求为：1）冗余度，2）梁、支撑和楼板的强度和刚度，3）防止楼层倒塌，4）轴力限制，5）构件强度劣化。2．如果拐角处的柱是刚性端柱，则框架的行为变得稳定。3．与其他框架相比，带有粘性阻尼器和销端柱的钢框架的响应较小，并且沿高度均匀。
