摘　　要：对对称三杆桁架承受载荷后的弹粘塑性平衡问题进行了分析。分析结果表明 ,桁架的变形可分为弹性变形、约束粘塑性变形、约束—自由粘塑性变形、自由粘塑性变形等 4个阶段。The viscoplastic balance of a symmetric three bar truss supporting the load has been analyzed. The analytical result indicates the truss deformation can be divided into four stages. They are 1) elastic deformation; 2) bind viscoplastic deformation; 3) bind and unbind viscoplastic deformation and; 4) unbind viscoplasticity deformation.
