In order to facilitate further promotion of the ecological composite wall, it was proposed a site walling ribecological composite wall, and research on the shear capacity calculation was done.The test of an ecological energysaving composite wall with 1/2scale under low-frequency cyclic loading was carriedout, and the test results wereanalyzed.It was analysed the main influencing factors of the shear strength of diagonal section of the now buildingstiffening rib ecological composite wall based on the experimental study.The general formula for the calculation of theshear capacityof the now building stiffening rib ecological composite wall was proposed based on related information, and applicable conditions of the formula were presented.By comparison between numerical simulation and test result, the calculation formula of shear bearing capacity of diagonal section of the composite wall was deduced, which couldbe used to guide practical engineering with relatively high precision and very clear concept.
