The Multi-ribbed composite wall frame column use steel concrete frame column, and thus Multi-ribbed composite wall becomes a new type structural system—the structure of the Multi-ribbed composite wall with steel concrete frame column. The wall retains the original merits such as heat preservation, heat insulation, environmental protection and earthquake resistance, etc.,further enhances the bearing capacity and stiffness, and displays the characteristics of concrete frame column. The present study selects the Multi-ribbed composite wall with one steel reinforced concrete structure as the research object, considers the bond-slip properties between steel reinforced concrete in the frame column of the wall, and by utilizing the large-scale project software ANSYS, carries on the numerical simulation analysis under similar load way, it compared with the experimental results. The main contents and research results were summarized as follows:(1) The test specimen of the Multi-ribbed composite wall with steel reinforced concrete frame column through the quasi-static test, learned the test-piece's stress characteristics, destruction characteristics and bearing capacity under the interaction of vertical load and reversed cyclic horizontal load.(2) According to the test model of size, material properties and load and restrain of forms, steel reinforced concrete of bond-slip properties was not considered, numerical simulation analysis of the wall frame column of the bottom section with steel strain-horizontal displacement curve, force phase of the maximum load and displacement, in addition the situation of the crack when structural cracked and damaged, compared with the experimental results, the error was very small, numerical analysis of model was reasonable.(3) Considered the Multi-ribbed composite wall with steel reinforced concrete frame column of between the steel reinforced and concrete of bond-slip capability, the numerical simulated situation of the above, as compared with the experimental values, the error was in the engineering analysis of the allowable range, consisted with the engineering analysis.(4) Finite element model under different ways loading, compared with analysis if considered wall structure of steel reinforced concrete of bond-slip capability, observed the differences among the structural stress, deformation, bond-slip.
