矿井井塔的梁柱刚度比对剪力滞后效应的影响
The Influence of Beam Column Stiffness Ratio of Mine Shaft Tower to Shear Lag Effect
【摘要】 利用大型有限元分析软件ANSYS,结合井塔的实际框筒结构工程进行建模分析,通过矿井井塔在水平荷载作用下的具体性能表现,得出梁柱刚度比对剪力滞后效应有较大的影响。再对梁柱刚度比对剪力滞后效应的现象进行分析,将计算结果与仿真分析的结果进行比较,提出改进方法。
【Abstract】 Making use of large finite element analysis software ANSYS,combine with the mine shaft tower actual frame tube structure project to model analysis,by means of concrete performance of mine shaft tower under the effect of horizontal load,come to a conclusion that beam column stiffness ratio has a great influence on shear lag effect.Then analyse the phenomenon of beam column stiffness ratio to shear lag effect,make a comparison on calculated results and simulation analysis results,to move an improved method.It has a great guiding significance for the mine shaft tower structural design.
【Key words】 mine shaft tower; horizontal load; beam column stiffness ratio; shear lag effect;
