| Abstract: | Methods for calculating the crack width and the stiffness of composite prestressed concrete beams,which link up with those of composite reinforced concrete beams and partially prestressed concrete beams, are proposed. These methods are more practical compared with those of the specification GBJ10-89 and in better agreement with the experimental data. |
