| 摘 要： | 利用圆柱壳的弹性薄壳小挠度理论公式推导出圆柱壳中无粘结预应力筋的等效荷载计算方法,并应用有限元软件ANSYS对结果进行了对比验证。同时也指出,预应力筋应该用来平衡外加荷载而不是直接用来平衡环向力。

| Abstract: | The computing method of equivalent load of unbonded prestressed reinforced steel bar in cylinder shell is gained by using the elastic small displacement theory formula and the results of caculation are compared with those obtained from ANSYS software.Meanwhile,it is emphasized that the prestressed reinforced steel bars are used to balance the applied load and not directly the annular internal force. |
