中文拼音 [niánzhāoxúbiàn]
粘著徐變
英文
bond creep-
Abstract : because the water - binder ratio of both high strength concrete and high performance concrete are very low, it bring about the following consequences such as : 1, the grade of cement strength would be a negligible symbol 2, the effectiveness of mineral admixture would be considerably improved 3, the high cohesion of the mixture and concrete " s shrinkage and creep would be changed etc. all these consequences should be well deliberated by the construction circles
文摘:高強混凝土和高性能混凝土因其水膠比都很低，給配製與施工帶來如下現象：水泥標號的「標志」作用淡化，礦物摻合料的作用顯著改善，拌合物的高粘聚性、混凝土的收縮和徐變性能的變化等，這些現象都值得施工人員注意。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
本文在國內外研究成果的基礎上，針對壓型鋼板與混凝土組合板結構在現代橋梁建設中廣泛應用前景和研究現狀，利用換算截面法導出了壓型鋼板與混凝土組合板結構的修正等效慣性矩；在此基礎上，又推出了考慮壓型鋼板與混凝土之間的相對粘結滑移影響的壓型鋼板與混凝土組合板結構極限抗彎承載能力計算理論，並介紹了考慮栓釘、聯結件影響的壓型鋼板與混凝土組合板結構簡化實用撓曲變形計算公式，而且通過與傳統計算理論的分析比較，表明本文提出的計算理論公式的準確可靠性；此外，採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構的徐變、收縮效應分析的計算理論和程序，並通過實例分析計算證明了理論的正確性、程序的可靠性和實用性。
