RESEARCH ON LOCAL BEARING CALCULATION OF MIDDLE CONCRETE COLUMN UNDER THE BILATERAL STEEL CORBEL

摘要：

The local bearing calculation of the concrete under the steel is much more important for steel hidden corbel of precast concrete frame. Base on the bearing ability characteristics of the steel in steel corbel joints of middle column, computation formulas of local bearing capacity of the concrete under steel are deduced, and some factors affecting the local bearing capacity are discovered. By the analyses of the hidden steel corbels with finite element software ANSYS, the design formula put forward in this paper is validated. The method to calculate the local bearing capacity in this paper, which covers the effect of the initial stress and the horizontal force transferred by the steel, has valuable information on designing analogical hidden corbels.
