【Abstract】 According to the experiment results of unbonded partially prestressed concrete members,it proposes a set of formulae which calculates the crack width of unbonded partially prestressed concrete flexural members and corresponds to the Chinese Code . Verified by the experiment results, the offered formulae are in high precision. Therefore, it can be used in the engineering design directly.更多还原
