Abstract

Abstract

The optimum design of prestress of a tensioned integral structure is studied. The states of self-stress are obtained by employing the method of singular value decomposition. The combination coefficients of self-stress states and cross-sectional areas of members are taken as the design variables. The mathematical model of optimization design is established and a sequential two-step algorithm is presented. Numerical example is provided to illustrate feasibility and correctness of the method.
- tensioned integral structure,
- prestress optimization,
- singular value decomposition
