Experiment Analysis On Several Knot-styles Of Beam-column For Multi-layer Steel Structure

The steel structure is the environment protective residential building .It is suitable to the conception of progressive development. The steel structure building will promote the increasing of the national economy effectively. With the enhancement of the establishing department, china steel structure institution residential steel structure branch institution have been established .Several seminar of residential steel structure is successively formed. Then many province areas have been collected on to put efforts to search for the best measured begin to establish the experimental resident houses. It is carried on our research in this field from the multi-resident steel structure knot of beam-column research. There are various of knot style including top- and seat- angle steel, top- and seat-angle with double web-angle steel connections, extended-end-plate bolted connections and so on. At home most pure theory is analyzed but experiment is seldom. In the Abroad experiment analysis and nonlinear finite element analysis of top-and seat-angle and top-and seat-angle with double web-angle connections have done, in this essay research in knot-style are differed. Therefore the key-note is different.The main research in this essay:1. Initial rotational stiffness Ri and ultimate moment capacity Mu of top-and seat- angle steel connections is given in this text. Initial rotational stiffness Rt and ultimate moment capacity Mu of top- and seat- angle with double web-angle steel connections is given in this text. It is right by comparison with experiment.2. Capacity P is concluded in ultimate moment capacity Mu and it is analyzed by method of Vp.3. Top- and seat- angle steel , top- and seat- angle with double web-angle steel connections is analyzed by experiment.4. General beam-column stiffness connections and the full-welded dog skeleton connection is analyzed and compared by Nonlinear finite element analysis method (ANSYS method) and draw some conclusions.
