Based on the analysis of outside core of unbonded partially prestressed flat beam-column joints, this paper proposes a new designed method for such kind of joint core,which is verified by test data. The advantages and disadvantages of the methods of GBJ10-89 code and other references are discussed. The conclusion is drawn that the method proposed by the author has clear concept and the calculation process is simple. All affecting factors are considered in the method. This method can be used in engineering design.
Keywords: flat beam-column joints; unbonded partially prestressed; outside core
