【Abstract】 Based on the character of the internal force distrbution of the statically indeterminate truss, utilizings the assembled stress makes the working state of bars of the structure in service to be adjusted more rationally. A conception named working state index of each bars is presented in this paper. On the basis of the criterion of the iso-strength, a concept called as reasonable working state index is also proposed for the structure in service.更多还原
