Through the testing of 4 reinforced concrete portal frames under peripheral loading, the degree of moment redistribution, the axial force influence on the limit loading as well as the behavior of frames after elastic moment adjustment have been investigated, with the full-range in elastic analysis being carried out. Besides, a limit analysis method using linear programming was presented. In this method, the static equilibrium functions include these variable quantities, i.e.moment, shear and axial force in ...
