摘　　要：通过合理添加支撑构件修正框架结构形态,具有重要的工程应用价值。基于以往研究成果,针对框架结构进行形态创构方法的应用研究,通过灵活使用节点移动和单元增减操作对框架结构形态修正,对不同荷载、不同初始形态下的框架结构合理形态进行探讨。结果表明,杆系结构形态创构方法可有效提高结构承载效率,使框架结构的主要内力从弯矩逐步转化为轴力。该方法为框架结构的形态设计提供了一种新的设计思路。Research of plane frame structural morphogenesis has a great significant application value by adding reasonable supporting members to amend their structural form. Based on previous research, application to frame structures was conducted by the morphogenesis method. Using flexible operations of node shift and element adding/eliminating to amend the frame shape, reasonable shape of the frame structure was discussed for different loads and initial structures. The results showed that this morphogenesis method can effectively improve efficiency of the frame structures, and the main internal forces of the frame structure gradually transformed from bending to axial force. This method provides a new design idea for frame structures.
