The irrepressible bloom, who also had a shrewd suspicion that the old stager went out on a manoeuvre after the counterattraction in the shape of a female, who, however, had disappeared to all intents and purposes, could, by straining, just perceive him, when duly refreshed by his rum puncheon exploit, gazing up at the piers and girders of the loop line, rather out of his depth, as of course it was all radically altered since his last visit and greatly improved
他定睛一看,才勉強辨認出那個灌了一肚子朗姆酒精神隨之而振的水手,正毋寧說是出神地仰望著環行線的陸橋橋墩和縱梁。當然自從他最後一次踏訪,這里已大大地改建,面目一新了。看不見形影的某人或某些人把男子小便池指給他看,那是衛生委員會為了衛生而到處蓋起來的。Sliding displacement of beam longitudinal bars in staggered joints is smaller than in ordinary joints, and the beam bar " overstrength in staggered joints is more serious than in ordinary joints when shear force is equal in the two types of joints

本文主要包括以下內容:從理論上研究並結合實測資料發展了一種比較理想的半經驗溫度場非線性分佈公式,並將有限元方法應用於剛架拱橋結構溫度應力的計算中,對橋梁結構進行整體溫度應力分析;討論了年溫差和日照溫差引起的橋梁結構的溫度效應,表明年溫差引起的溫度效應較小,而日照溫差引起的溫度應力較大且沿梁高呈非線性分佈;分析比較了橋梁結構各個部位的溫度效應的大小,可知截面越小溫度拉應力越大,受力越不利;並對箱梁結構由於構造不同引起的縱向與橫向的溫度效應大小進行了探討,發現在頂板下緣也會出現相當大的溫度拉應力,並且梗腋的存在反而增加了頂板底部的溫度拉應力;還對幾種相近的剛構式橋型的溫度效應進行了分析對比,總結了這些橋型針對溫度效應的優劣,並提出相應的針對性措施。Then, if your view ran along the bank, from east to west, from the tournelle to the tour de nesle, there was a long cordon of houses, with carved beams, stained - glass windows, each story projecting over that beneath it, an interminable zigzag of bourgeois gables, frequently interrupted by the mouth of a street, and from time to time also by the front or angle of a huge stone mansion, planted at its ease, with courts and gardens, wings and detached buildings, amid this populace of crowded and narrow houses, like a grand gentleman among a throng of rustics
如果再縱目從東向西,從小塔向納勒塔遠望,只見長長一帶房舍,雕梁畫棟,彩色玻璃窗戶,層層疊疊,突出在石路上方;還可以看見一派市民房舍的山墻,曲曲折折,望也望不到盡頭,時常被一道街口所切斷,也不時被一幢石墻大樓的正面或側面所切割;大樓四平八穩,連同庭院和花園,廂房和主體,夾在那彼此緊挨著的狹窄民舍當中,猶如一個領主老爺夾在一大堆平民百姓中間。Then the coupling beams with new reinforcement layout were made an inquiry into, and the improvement on the seismic behavior by coupling beams diagonally reinforced with a few rows in end regions was found out at last, based on the observations of the experimental phenomena and the analysis of the measurement result, and by the comparison of seismic behavior by making use of hysteretic response, ductility and energy dissipation behavior, a conclusion is presented : the code for design and construction of reinforced concrete high - rise structures ( the draft asked for advise hi 2000 ) ca n ' t ensure that the coupling beams have fairly good seismic ductility ; the result of improvement of the seismic ductility of the coupling beams by the increase hi stirrups besides the strengthen of longitudinal detailing reinforcement was n ' t obvious ; the coupling beams diagonally reinforced with a few rows in end regions have fairly good mechanisms, and the ductility and the behavior of energy dissipation are better than conventionally reinforced concrete coupling beams, so it is suitable to te tised in short coupling beams
本文通過對三根小跨高比(均為l h = 1 . 0 )剪力墻洞口連系梁在低周反復荷載作用下的試驗,了解了嚴格按《鋼筋混凝土高層建築結構設計與施工規程》 ( 2000年徵求意見稿)設計的連梁具有的抗震性能,研究了採取增大連梁配箍量同時加強縱向構造筋的方案對抗震性能的影響,並進一步對新的配筋形式的連梁進行了探討,了解了在連梁梁端配置多排交叉斜筋方案對連梁抗震性能的改善。通過對試驗現象的觀察和量測結果的分析,利用荷載?位移滯回曲線、延性和耗能性能等指標對各個試件的抗震性能進行了比較,最後得出結論: 《鋼筋混凝土高層建築結構設計與施工規程》 ( 2000年徵求意見稿)不能保證小跨高比連梁具有較好的抗震延性:通過增大連梁配箍量同時加強縱向構造筋的方案對改善連梁的抗震延性的效果不太明顯;梁端配置多排交叉斜筋的連梁具有相對較好的受力性能,其延性和耗能性能等各項性能指標均優于普通配筋連梁,宜在深連梁中採用。5. the formulae that the lately issued code for design of concrete structures gb50010 - 2002 offered are applicable for design of staggered joints, considering joints failure not serous and the difference very little between calculative values and experimental values of staggered joints
考慮到梁中縱筋配筋偏低,節點破壞輕微,節點抗剪承載力計算值與實驗值相差很小,故可認為新頒布的《混凝土結構設計規范gb50010 - 2002 》給出的公式仍可用於錯層節點的計算。Through the experimental and theoretical analyzing results, the conclusion can be summarized as follows. 1 ) the yielding load and ultimate bearing capacity of the beam are not affected by the value of the load under that load the cfrp sheets were retrofitted, but the value will affect the stiffness of the beam, especially the average tangent stiffness after rebar yielding. 2 ) the stiffness of cracked beams retrofitted with cfrp sheets is larger than that of the normal rc beams
