| Abstract: | In this paper, the first - raised method of directly calculating sencondary moments in prestressed statically indeterminate structure by calculating restrained sencondary moments, is presented. And its physical thoughts is clear, with a simple formula. When it is used in Computer Programming, the method will be easy to adopt the existing computer programs of ordinary concret structure. However, it is also convenient and direct when used in calculation of manual work- Furthermore, the methord causes the formulas of pre-stressing varing, or not , along the prestressed tendons due to prestressing losses become the same one, and it makes the calculation more simple and direct. |
