采用荷载平衡的概念表达预应力度及在初步设计中的应用

The Pre-stressing Force Degree Expressed by Using the Concept about Method of Load Equilibrium and Applied in Initial Design

利用荷载平衡法的概念 ,将预应力度用等效荷载与外荷载的比值表达 ,设计者可利用其比值确定预应力度 ,使其更简捷、明确 .同时 。

The article explains the degree of pre-stressing force through the ratio between equivalent load and external load,by using the concept about method of load equilibrium.The designer can define the degree of pre-stressing force by the ratio,and the method is simple,direct and clear.At the same time,the real value about the degree of pre-stressing force is put forward.
