【摘要】 运用有限元分析软件SAP2000对预应力撑杆式钢压杆进行模拟分析,将所得结果与欧拉临界承载力进行对比分析,分析结果表明,施加预应力后的钢压杆的承载能力相较非预应力钢压杆提高较多,但与欧拉临界承载力之间仍有一定差距。更多还原

【Abstract】 The paper adopts the finite element analysing software SAP2000 to have the simulation analysis of the prestressed strut-type steel column,undertakes the comparision and analysis between the results and the Euler critical loading capacity,and proves by the analysis results that the loading capacity of the prestressed steel column is improved more than the steel column without the prestress,but there is still some distance between the prestressed steel column and the Euler critical loading capacity.更多还原
