| Abstract: | This paper defined the secondary moments in prestressed concrete structures.It showed us the reasons of the secondary moments coming into being detailedly and list three common methods about calculating the secondary moments.It also presented some basal factors that effected the secondary moments.At last in order to explain the method,this paper also showed us an example.So it could be regarded as reference information when considering the secondary moments. |
