| 摘 要： | 在预应力砼构件中,由于种种原因,预应力会损失掉一部分,总损失约占控制应力的30%左右。设计时必须先将其计算出来,得出构件中的有效预应力,进而确定构件各阶段的应力状态。长期观测得知,高性能砼构件的预应力损失要比普通强度砼的损失大。

| Abstract: | In prestress concrete components,there will be some loss of prestress due to various reasons,and that amounts to 30% of the control stress. It should be calculated out in designing,and elicit the effective prestress in components to help determine the stress state of components stages. It is known that the loss of high performance concrete components is more than that of low performance concrete components from long-term observation. |
