  1. Local buckling capacity of steel composite beam subjected to combined bending, shear and patch loading is one of key problem in steel structures design. the computational formula for local stability of web was based on the assumption of infinite - elastic perfect plates in the steel structures design code ( gbj17 - 88 ). but in the revised code ( gb50017 - 2003 ), this formula was made big change with reference to british code ( bs5950, partl ) and australian code ( as4100 ), the related research result of our country was included as well. in the modified formula, influence of early geometric imperfection and elastic - plastic buckling stage were considered, which is compatible with both actual circumstance of engineering and the strength formula of beams under bending stresses ( considering partial plasticity of the section ). in this paper, the preceding problem is deeply analyzed and studied, considering the effects of various geometric parameters and stress combinations on buckling critical stress of web, the revised local buckling correlative formula for transverse and longituded stiffened web panels under combined stresses is analyzed and verified by finite element method

    組合鋼梁腹板在彎、剪及局壓復合應力作用下的局部屈曲承載能力是鋼結構設計中需考慮的問題,新的《鋼結構設計規范》 ( gb50017 ? 2003 )對此部分內容作了較大改動,原規范中關于腹板局部穩定的計算公式是基於無限彈性的完善板假定;新的規范則參考了英國規范( bs5950 part1 )及澳大利亞規范( as4100 )並結合我國相關研究成果,考慮了屈曲進入彈塑性階段以及初始幾何缺陷的影響。這不僅與工程實際情況相符,而且也與鋼梁在彎曲應力作用下允許截面部分進入塑性的計算公式相協調。
  2. The program fearpv is applied to 3 - d transient sealing analysis of nuclear pressure vessel during the total process, including bolt pretensioning process, heating and compression process, thermostated heating and constant pressure process, and the cooling and decompressing process. according to the analysis and computational results in this thesis, although the actual structure and work conditions of the pressure vessel in nuclear power station are much more complex than that of the pressure vessel model, the program fearpv still can get quite good convergence on the plasticity and

    由本文分析計算可知,雖然電站核壓力容器的結構及計算工況較壓力容器模擬體復雜得多,然而反應堆壓力容器瞬態密封有限元分析程序對塑性迭代和接觸迭代仍具有很好的收斂性,數值穩定性好,得到的結果具有良好的規律性,在升溫、升壓、恆溫、恆壓、降溫和降壓等過程中其規律和壓力容器模擬體基本相似。
