钢框架梁柱T型钢连接节点滞回性能的研究
|
摘要
用ANSYS对T型钢连接节点进行滞回性能的分析,在考虑材料、几何和状态非线性的基础上,系统分析了各种参数对连接滞回性能的影响,分析表明:T型钢的尺寸、是否设柱加劲肋、T型钢翼缘上螺栓的竖向间距对连接的滞回性能影响比较大,并在非线性有限元分析结果的基础上,提出了钢框架T型钢连接的滞回模型。
The hysteretic behavior of the T-stub connections were analyzed by ANSYS program.Secondly,based on the consideration of combined nonlinearity of material,geometry and state of connections,systematic analyses were put on the parameters that influence the hysteretic behavior,the results showed that the dimension of T-stub,stiffeners,vertical interval of bolts greatly influence the hysteretic behavior of the connections.Lastly,based on the nonlinear FEM analysis,the hysteretic model of steel beam-to-column T-stub connections were gived.
