( Technical Center of Shanghai Xian Dai Architectural Design( Group) Co. ,Ltd., Shanghai 200041, China)Abstract: Strength and rationality of cable joint will affect reliability of the beam string structure, so it used to be made of cast steel. A cast steel cable joint was analyzed by nonlinear finite method in 3 times of design load. Development process of stress and strain, strength and extreme load of node are obtained. The results provide sufficient data for projects.
Keywords: beam string structure; cast steel joint; finite element method; non-linear analysis
