以弹性阶段直线配筋的无粘结预应力混凝土梁为例 ,推导了在均布荷载作用下按能量法求解无粘结预应力筋应力增量的过程 ,并以实例与目前已有方法所求得的应力增量进行了比较 ,验证了按能量法求解的可靠性
Taking the non-bonded prestressed concrete beam with linear reinforcement in the elastic phase as an example, the process of solving the stress increment of unbonded prestressed tendons by the energy method under uniform load is deduced. Based on the examples and current methods The calculated increment of stress is compared to verify the reliability calculated by energy method
