Abstract: Having studied bending and compressing-bending ultimate failure test of three new EVG － 3D walls，the mechanical characteristics of wall panels，combined action of two plates of concrete and the steel wires with concrete were analyzed in this paper． Based on the test results of bending and compressing-bending of EVG － 3D wall panels， calculation formulas for flexural and shear bearing capacity were researched simultaneously． These results obtained are served as a basis for compiling engineering regulations of this new composite wall material．
