| Abstract: | In this paper, The representational 3D FEA model is set up for haunch joints of steel fram structure. Stress distribution is got by nonlinear analyzing of the model. The characteristic and rule of stress distribution in haunch node and ordinary node is analyzed for contrast. Under the cyclic load function, gave the node to stagnate the curve, then obtained the haunching to be possible to improve the node obviously ductility, the force node plastic hinge offset, provided the basis for the node design. |
