The authors are devoting themselves to construction of a hysteretic constitutive model for reinforced concrete(RC) panels under reversed cyclic in-plane stresses to be used in Finite Element Analysis. They have already proposed an elasto-plastic hysteretic constitutive model of RC panels subjected to reversed cyclic, in-plane shear stress. To establish a more general constitutive model, a test series of RC panels subjected to reversed cyclic combined in-plane shear and normal stresses were conducted and a new model was constructed based on the test results. The model modifies the decrease in compressive strength for cracked concrete depending on tensile strain normal to crack direction. It also newly formulates the decrease in yield strength for embedded reinforcing steel bars based on the test results. The appropriateness of the proposed analytical model was verified by applying it not only to the authors' tests but also to other existing RC panel tests.
