摘要: 约束次内力法是求解预应力超静定结构内力的一种方法。根据约束次内力法的原理,针对体外预应力加固工程的实际需要,直接给出数种预应力线型布置在三种约束下的约束次内力公式,并基于该方法讨论了力筋线型对体外预应力连续梁的预应力效果的影响。Abstract: The method of secondary moment under restraint is a convenient way to solve the interior force of prestressed statically indeterminate structure. Based on this method, the secondary interior force of all kinds of external tendon profile under three restraint conditions are directly provided in accordance with practical requirement in the construction application,and the relationship between profile parameters and prestressing effects on continuous beams are established.
