1. On the basis of relative researches in the world , according to the study status of steel - concrete composite slab , which would be widely used in modern bridge , modified equivalent inflexibility of steel - concrete composite slab was deduced by use of conversion section principle in this paper ; based in this , this paper put forwards the theory of ultimate flexural capacity of steel - concrete composite slab in consideration of slip effect , and introduces the practical simplified method for calculating flexural deformation of steel - concrete composite slab in consideration of the effect of steel studs and welded wire , and conclude that the methods in this paper is veracious and reliable , comparing with the traditional calculating mode ; morever , this paper put forwards the calculating theory and program of the effect analysis of creep and shrinkage to steel - concrete composite slab , using conversion elastic modulus principle , and testifies that the theory is right and the program is reliable and practical
   本文在國(guó)內(nèi)外研究成果的基礎(chǔ)上，針對(duì)壓型鋼板與混凝土組合板結(jié)構(gòu)在現(xiàn)代橋梁建設(shè)中廣泛應(yīng)用前景和研究現(xiàn)狀，利用換算截面法導(dǎo)出了壓型鋼板與混凝土組合板結(jié)構(gòu)的修正等效慣性矩；在此基礎(chǔ)上，又推出了考慮壓型鋼板與混凝土之間的相對(duì)粘結(jié)滑移影響的壓型鋼板與混凝土組合板結(jié)構(gòu)極限抗彎承載能力計(jì)算理論，并介紹了考慮栓釘、聯(lián)結(jié)件影響的壓型鋼板與混凝土組合板結(jié)構(gòu)簡(jiǎn)化實(shí)用撓曲變形計(jì)算公式，而且通過與傳統(tǒng)計(jì)算理論的分析比較，表明本文提出的計(jì)算理論公式的準(zhǔn)確可靠性；此外，采用換算彈性模量比法著重提出了壓型鋼板與混凝土組合板結(jié)構(gòu)的徐變、收縮效應(yīng)分析的計(jì)算理論和程序，并通過實(shí)例分析計(jì)算證明了理論的正確性、程序的可靠性和實(shí)用性。
