縱向拱 的英文怎麼說
中文拼音 [zōngxiànggǒng]
縱向拱
英文
longitudinal arch-
On the contents of two sides abovementined, this paper attempts to do some initial researches from three angles as follows : 1, the analyses of anti - seismic features on longitudinal direction of the aqueduct l ) the seismic longitudinal effects are small. the vibrant characters are decided from the structure integration and rigidness of piers and main arch - ring of the aqueduct, so the following measures should be taken in order to weaken and isolate seismic influence : properly broadening the section sizes and adopting the high class concrete, lowering the height and barycenter of building, setting hoop steel bars so as to increase the plasticity of the concrete which can absorb the seismic energy and prevent the damages due to stress centralization on the linkages and changing place
本文試圖就上述的這兩大方面的內容，從以下三個角度進行了初步研究： 1 、縱槽向抗震性能分析1 ）湯峪河吊桿拱支承結構的縱槽向地震效應較小；吊桿式拱架結構動力特性取決于槽墩和主拱圈的剛度，以及結構的整體性，故適當加大構件截面尺寸或提高砼標號，盡量降低結構的建築高度和重心，在構件連接和變截面處增設梗脅，按照約束混凝土的要求來加強箍筋的配置，增加砼的延性，以克服地震時構件連接和變截面處的應力集中造成的坡壞，並吸收大量的地震能量，從而起到隔震，減震的效果。A few paces off is an enormous pillar, and another ? seven in all down the length of the hall, supporing in the centre line the springing arches of the double groining
幾步開外有根高大的柱子，接著又一根，再接著又是一根；大廳縱深一共豎著七根大柱，支撐著雙拱屋頂落在橫向正中的拱底石。The set of tectonic cracks on down beam is beneficial to anti - seism along the longitudinal and side long of aqueducts
拱架下弦桿分縫斷開的做法對縱、橫槽向抗震的最終效果是有利的。The contents include : based on the previous research and the data of experimentations, the author researches and develops a kind of satisfactory semi - empirical formula of nonlinear temperature distribution, and calculates the temperature stress of rigid - framed arch bridge by the fem. the temperature effects of bridge structure by annual and sunlight temperature difference are discussed, it indicates that the temperature effect of annual temperature difference is small but the temperature effect of sunlight temperature difference is great and the temperature stress along beam depth resulted from sunlight temperature difference is nonlinear. with the comparison between the temperature effects of different position of bridge, the results show that where the section of bridge is small, the temperature stress of it is large
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。A steel tubular trssed structure was vertically fixed to ensure the stability of the plane surface of the arched girder
為保證鋼梁在變異拱處平面外的穩定，縱向設一通長管桁架。Study on the cause of the longitudinal lining cracking in the crown of arch of double arch road tunnel
