摘要
本文以结构系统势能驻值原理为基础,提出了无粘结预应力混凝土超静定结构预应力钢筋应力计算的能量法,给出了无粘结预应力混凝土梁连续在均布荷载作用下无粘结预应力筋应力增量的求解过程,并与已有方法进行了比较,验证了按能量法求解的实用性。
Based on the principle of minimum potential energy of structure system, in such a hyper static structure as unbonded prestressed concrete bridge, this paper presents an energy-method for stress calculating of unbonded prestressing reinforcement, advances the whole solution procedure of stress increment of unbonded prestressing reinforcement subjected to the uniform load and compares it with the exiting method, thus demonstrates the practicability of the solution in energy-method.
