全波纹腹板H型柱的弹性屈曲

ELASTIC BUCKING OF WHOLE-CORRUGATE WEB H-BEAM

摘要: 运用变截面梁单元有限元法和MATLAB高级编程语言对全波纹腹板H型钢在轴心压力下的屈曲性能及其参数对临界荷载的影响进行了分析,并且与等截面H型钢进行对比,用实例说明了全波纹腹板H型钢的优越性,为这种H型钢在工程中的应用提供了理论依据.

Abstract: This paper applies the finite-element method for beam of variable section and the programminglanguage of MATLAB to analyze the buckling strengthof whole-corrugated web H-beam under axial pressure, and the comparison with constant cross-section H-beam shows the superiority ofwhole-corrugated web H-beam.
