Based on the previous research on the portal crane administration, one standpoint put forward in this paper is idea that is on the foundation of reliability in this paper, two viewpoints take shape when reason is analyzed, that is fatigue break and appearing the flaw that will extend. what is the fatigue break ? ( this phenomenon is always happen in some place ), the fatigue is that board appears apophysis and concave when the board is pressed. so that the board ability of bearing the weight of load will descend
本論文建立在已有的港口裝卸機械管理的研究基礎之上，進一步提出了以可靠性為基礎的港口裝卸機械的管理思想，已有的研究表明，港口機械設備破壞主要由於兩個原因，第一是穩定性問題，特別是構件的局部穩定性，所謂穩定性是指：在板的平面內，板受到平行於板面的壓力作用，使板發生隆起、內陷等凹凸不平的結果，從而使板受載能力減弱；第二是結構出現疲勞裂紋及其擴展，這是由於設備長時期運行，而造成設備某些部位出現裂紋並得以擴展，使設備承載能力下降。Imitate the old floor in the style of the ancients : adopt wood assortments such as birch, oak wood, color wood, elm to be base material, by that the manpower surface plane is sure to process the roughness handling the different in soaking various colour and lustre of forest paint, reaching
仿古仿舊地板：採用樺木、柞木、色木、榆木等材種為基材，經人工表面刨切加工處理在浸林各種色澤不同的油漆，達到凹凸不平。Referring to three kinds of plan irregularity, structures individually with four kinds of irregularity as eccentricity in one direction, eccentricities in two directions, re - entrant corner irregularity and diaphragm discontinuity have been analyzed to investigate the relationship between torsion effects and parameters of above irregular structures. the parameters and the schemes for determining the scope of structures with different kind of irregularity considering seismic action in two directions simultaneously are proposed, some conclusions have been get as following : it is indicated by the analysis results that torsion effect has no dependency relation with eccentric torsional angel adopted in code for seismic design for buildings. it is suggested that the eccentric torsional angel should not be take as the parameter of torsion effect of structures considering seismic action in two directions simultaneously ; for the structures with regular plan and elevation and with eccentricity in one direction due to irregular mass layout, the relative eccentricity can be take as the parameter of torsion effect of structures considering seismic action in two directions simultaneously ; for the structures with regular plan and elevation and with eccentricities in two directions due to irregular mass layout, the ratio of relative eccentricities in two directions and the angel of them can be take as the parameters of torsion effect of structures considering seismic action in two directions simultaneously ; it is indicated by the analysis results that the torsion effect has no dependency relation with re - entrant corner ratio adopted in code for seismic design for buildings as
所取得的主要結論有：結構的扭轉效應與《抗震規范》所採用的扭轉不規則指標即偏心扭轉角之間的相關性較差，偏心扭轉角不宜作為判斷結構是否計及扭轉效應及需考慮雙向水平地震作用的界定指標；對于樓層間均勻偏心的多層單向偏心結構，建議採用相對偏心距作為需考慮雙向水平地震作用的界定指標，並給出針對不同平面尺寸的界限相對偏心距；對于樓層間均勻偏心的多層雙向偏心結構，建議採用兩個主軸方向的相對偏心距及其夾角作為界定指標，結合單向偏心結構的界定方案進行需考慮雙向水平地震作用的結構范圍界定；凸凹不規則結構的扭轉效應與凸凹比例無正相關關系， 《抗震規范》要求所有平面布置不對稱的凸凹不規則結構計及扭轉效應的規定欠妥當，建議凸凹不規則界限值從30改為15 ，只要求分析採用空間模型比較合適； 《抗震規范》關于有效樓板寬度較小的結構需計及扭轉效應的規定很有必要，樓板局部不連續的結構需採用符合樓板實際剛度的計算模型予以分析，可使用相對偏心距（及其夾角）參照單向（和雙向）偏心結構的界定方案，界定樓板局部不連續結構是否需要計入雙向水平地震作用下的扭轉效應。
