摘要
对钢管、角钢和箍筋(缀板)以及内外混凝土构成的新型组合柱的压缩性能作了研究,应用有限元软件ANSYS对组合柱的破坏过程进行数值模拟,通过与试验测试数据的对比,对轴压作用下柱破坏过程中裂缝开展情况,各组分的应力变化进行了分析,利用大量的数值计算数据,基于基本假定,构建新型组合柱轴压承载力计算公式,通过试验数据进行了可靠性验证。
The paper researches the compression performance of the new concrete-filled column with Steel pipes, steel angle and stirrup and the internal and external concrete, adopts the finite element software ANSYS, to undertake the numeric simulation of the damage process of the concrete-filled column, analyzes the stress changes of all parts in the cracks of column damage process under the effect axial pressure by comparing test data, uses a lot of numeric calculation data, establishes the new concrete-filled axial pressure capacity calculation formula based on basic assumption, and undertakes the reliable checking according to the test data.
