Second order analysis of diffraction of stokes waves by a vertical cylinder 波在鉛垂圓柱上繞射的二階分析
A practical approach of second order analysis for the huge steel frame structure 巨型鋼框架結(jié)構(gòu)的二階實(shí)用分析
Introduced the second order analysis of the thin - walled members based on the theory of the rotation of a cross section around a fixed axis , and discussed the general methods of the loading capacity and the space stability coefficient for the thin - walled columns . used a programme , a large amount of space stability coefficient of t - shaped and l - shaped axes columns with a initial bend was computed to gain the curves of the columns . the procedure of the computation behaved the simplification and the convenience of the method 介紹了以定軸轉(zhuǎn)動(dòng)理論為基礎(chǔ)的薄壁柱空間穩(wěn)定二階分析方法,初步論證了以此為基礎(chǔ)的薄壁柱空間穩(wěn)定承載力的驗(yàn)算及空間穩(wěn)定系數(shù)的計(jì)算方法,并借助程序?qū)哂谐鯊澢母鞣N“ t ”形和“ l ”形軸壓柱的空間穩(wěn)定系數(shù)進(jìn)行了計(jì)算,作出其柱子曲線圖,從而驗(yàn)證了此方法的可行性和簡(jiǎn)便性,同時(shí)提出以此為基礎(chǔ)對(duì)鋼結(jié)構(gòu)截面優(yōu)化的方法。
