箱形截面柱 的英文怎麼說
中文拼音 [xiāngxíngjiémiànzhù]
箱形截面柱
英文
box section column-
The effect of different sizes of sections, modes and values of residual stresses are studied. through the analysis, the conclusion is arrived at that the universal slenderness ratio should be used to better correlate the stability of box section beams with the member length instead of the out - of - plane slenderness, and the stability coefficient is taken to be 1. 0 for practical used box girder. then, the elastic critical loads of box section beam - columns are obtained based on the gjelsvik theory, and the relationship between axis force p and moment m is given
最後，運用ansys通用有限元程序的beam189單元，引入初彎曲和殘余應力的影響，用考慮幾何和材料雙重非線性的有限元求解格式求得箱形柱在不同軸力和彎矩比例作用下的彈塑性極限承載力，通過對十幾個不同截面尺寸構件在不同長細比下的承載力計算，發現在軸力p遠大於彎矩m時，構件將是平面外失穩控制，而當軸力p遠小於彎矩m時，構件則以平面內失穩為主。Finally according to the load - capacity superposition concept, a simplified design equation for determination of the load capacity of circular composite columns with h - shaped and box - shaped structural steel is proposed. through comparison with the accurate computer - based method, it is found that the proposed simplified equation is accurate enough and can meet the requirement of practical applications
同時基於承載力疊加的概念，提出了配置工字型和箱型結構鋼的圓形截面組合柱在單向和雙向偏壓荷載下的承載力簡化計算公式，通過與精確的計算機數值迭代方法的比較發現，當荷載偏心較小時該簡化計算公式具有足夠的準確度，能夠滿足工程應用的要求。With the better torsion performance of box section beams and beam - columns than members with open cross - section and the progress of the manufacturing technology of box section members, the box section members find wider and wider application, especially in high rise buildings
箱形截面梁與樑柱由於較其它形式的截面具有較好的兩個主軸方向抗彎剛度和抗扭剛度，隨著鋼結構的不斷發展，箱形構件製作工藝的完善和日趨成熟，箱形截面構件的應用越來越廣，尤其是在多高層建築中。
