This paper applies the finite-element method for beam of variable section and the programming language of MATLAB to analyze the buckling strength of whole-corrugated web H-beam under axial pressure, and the comparison with constant cross-section H-beam shows the superiority of whole-corrugated web H-beam.
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。
A modified Jezék method is presented to study the post-buckling behavior of axially restrained steel columns at elevated temperatures in fire.
提出了一种改进的Jezék方法,用于火灾升温下轴向约束钢框架柱屈曲后性能分析,高温条件下钢材的应力-应变关系考虑了钢柱屈曲后凸侧可能出现的卸载现象。
The more significant amplitude of the weld imperfection will reduce the buckling bearing capacity of the cylinder,but the amplitude has little influence on the post buckling performance.
研究表明:环向焊缝缺陷对于柱壳承受局部轴向压力造成很大的影响,当焊缝位于完善柱壳后屈曲模态最大内凹处时,影响最为不利;缺陷幅值越大屈曲承载力越低,但是对于后屈曲性能影响很小;相邻焊缝缺陷的相互影响对柱壳的屈曲承载力略有提高。
