A yield criterion for the steel-concrete-steel (SCS) unit panel subjected to in-plane membrane forces is proposed, which is expressed in the in-plane (principal) stress space and follows the Tresca yielding principle for steel plates. This yield criterion for the SCS unit panel is based on the Navier’s three principles (equilibrium conditions, strain compatibility, and the constitutive laws of materials). A calculation method for determining the yield load of the SCS unit in combination with the test data is proposed, and the method is applied to the bidirectional tensile and compression test of the SCS unit. By using this method, nine SCS tested panels with different steel ratios and different tension compression ratios are analyzed, and the yield criterion of the SCS unit is compared with the test results. In addition, seven SCS shear specimens tested by Ozaki are used for further verification. The results derived from the yield criterion of the SCS panel elements are found in good agreement with the test results.
