SCLC框架结构抗震性能有限元分析

在自密实轻骨料混凝土（SCLC）框架结构拟静力试验的基础之上，运用大型有限元软件MARC对SCLC框架结构进行了分析．在分析结果与试验结果吻合的情况下，改变SCLC框架柱的轴压比后，进行有限元分析．通过滞回曲线，骨架曲线的比较，研究不同SCLC框架柱的轴压比对SCLC框架结构的抗震性能影响．由数值模拟结果可知：轴压比越小，SCLC框架结构的抗震性能越好．这与“普通混凝土框架结构框架柱受轴压比越小其抗震性能越好”的成熟结论一致，说明SCLC框架结构在抗震方面与普通混凝土框架结构具有共性，为SCLC框架结构的推广应用提供了理论依据．

Finite Element Anlysis of SCLC Frame Structure Seismic Performance

On the basis of the self- compacting lightweight aggregate concrete （ SCLC ） frame structure static test, this paper uses the large finite element software MARC to analyse SCLC frame structure. In the case of analysis results with the test results,it changes the SCLC frame column of axial compression ratio to have the finite element analysis. Through the hysteresis curve, skeleton curve comparison, research different SCLC axial compression ratio on SCLC of frame column frame structure seismic performance influence. By the numerical simulation results indicate：The smaller the axial compression ratio is, the better SCLC frame structure seismic performance is. It is consistent with the mature good conclusion about ＂the smaller axial compression ratio of ordinary concrete frame structure frame column is, the better seismic performance is＂, It illustrates that SCLC frame structure and ordinary concrete frame structure is common in aseismic, and provides theory basis for SCLC frame structure popularization and application.
