钢筋和型钢混凝土异形柱的静力和动力有限元分析
|
摘要
目的验证SRC和F-SRC结构的性能,为试验研究和实际工程应用提供参考依据.方法笔者运用有限元软件对型钢混凝土异形柱构件的受力性能进行模拟计算,采用模态分析的方法对其在不同配钢率下的自震周期进行研究,并对配钢率为6.11%的柱进行振型分析.结果普通钢筋混凝土异形柱在加入型钢后承载力大幅度提高,加入型钢钢骨后柱的耗能效果更明显,且抵抗竖向地震作用的能力也比无骨柱有所提高.结论虽然F-SRC相比于SRC在承载力上提高一些,但同时也会造成材料的大量消耗.自振周期随配钢率的增大而减小,说明构件的刚度随配钢率的增大而增大.
To verify the performance of the SRC and F-SRC structure,to provide a reference for the pilot study and practical engineering applications.The author used the finite element software simulation of the mechanical properties of steel reinforced concrete special-shaped column member,and used modal analysis method to study the earthquake cycle with different steel ratio.And the rate of 6.11% with steel column modal analysis of ordinary reinforced concrete columns after joining section steel carrying capacity greatly improved by adding section steel SRC the effect is more pronounced after column energy consumption,and the ability to resist vertical seismic action than boneless column increased.Although compared to the SRC increased carrying capacity to some extent,at the same time F-SRC can also cause a large number of materials consumption.Vibration period increases as steel ratio decreases,the stiffness with steel distribution rate increases.
