【Abstract】 An analysis method for the connections of prestressed concrete slab to interior column under shear and unbalanced moment is proposed in this paper by applying the plastic limit state theory. The symmetry of connections is employed to facilitate the application of the plastic limit analysis. A set of equations are derived to predict the ultimate strength of P.C. Slab interior column connections under shear and unbalanced moment. The comparison of calculated and tested results shows that the propopsed method and equations are relatively accurate and therefore can be used in engineering practice.更多还原
