为进一步研究自密实轻骨料混凝土结构的抗震性能,采用通用有限元软件Msc.marc2005r2对一根自密实轻骨料混凝土框架柱进行滞回分析,并在此基础上进行参数分析。计算结果表明:有限元模拟滞回曲线与试验曲线吻合较好;轴压比的增加,承载力变化不大,但构件极限位移变小;配筋率的增加能增大构件极限位移;轴压比在某一特定值时,增大配筋率对于极限位移影响很小。
In order to further study the seismic performance of self-compacting lightweight aggregate concrete structures, a hysteretic analysis of a self-compacting lightweight aggregate concrete frame column was carried out by using the general finite element software Msc.marc2005r2. Based on this, the parameter analysis was carried out. The calculation results show that the simulation curves of the hysteretic curves are in good agreement with the experimental curves. The increase of the axial compression ratio does not change a little while the ultimate displacement of the members becomes smaller. The increase of the reinforcement ratio can increase the ultimate displacement of the members. Compared with a certain value, increasing the reinforcement ratio has little effect on the limit displacement.
