型钢混凝土柱循环荷载下的数值模拟
|
摘要
利用有限元分析软件ABAQUS建立两组钢骨混凝土柱与普通混凝土柱的对比分析模型,进行了单调加载与循环往复加载下的非线性有限元分析,分析结果发现,柱轴压力系数的变化对型钢混凝土柱的耗能有一定影响,计算结果对工程型钢混凝土柱的设计和应用有一定指导作用。
Two groups contrasting analysis models referring to SRC column and RC column are established by using finite element software ABAQUS,under takes the non-linear finite analysis under the monotonic loading and the reversal load pattern,analyzes the results and finds the changes of the column axial pressure coefficients have the certain influence on the consumption of the steel concrete column.The study results have some value on the design and application of the SRC columns.
