孔肋加劲钢管混凝土柱轴压受力性能有限元分析
Finite element analysis on axial compressive mechanical behavior of concrete filled steel tubular column with holes rib stiffener
摘要
Abstract
T he poor bonding properties of ordinary steel tube and the core concrete have had less effect upon the stress properties of integral components .In this paper ,the stiffening rib on the inner wall of steel pipe is opened with some holes ,so as to more the concrete holed through the holes bonded ,formed a plurality of shear connectors ,thus effectively improving the bonding per‐formance of steel and concrete ,increasing the “confinement effect” of steel tube and the compo‐nent integrity .Through the axial compression finite element analysis ,it is found that :the maxi‐mum stress of concrete filled steel tubular column with holes rib stiffener should be close to the central section and the stress distribution of the component is more uniform .This new type of concrete filled steel tubular column has simple structure as compared with the ordinary form , with has higher bearing capacity and deformability .关键词
