摘要
应用突变理论建立了两端铰支的压弯构件失稳的尖点突变模型。借助数学方法 ,描述了压弯构件失稳过程中平衡的特性 。
Based on catastrophe theory, the paper establishes cusp catastrophe model of instability of simply supported beam column. With the help of mathematics, the author expounds the characteristics in the process of destabilization of beam columns, and presents conclusions and a formula of the relationship between lateral displacement of the member and applied load.
