style="text-indent:25px">美觀是鋼橋設計必須考慮的一部分：城市鋼橋建筑不僅是交通工程中的重點建筑物，鋼橋深化設計軟件價格，而且也是美化環(huán)境的點綴品，所以設計必須精心方案比選、精心設計、精心施工，以期求得在增加投資不多的條件下，取得橋梁美觀的效果。比如在城區(qū)建一座二，鋼橋深化設計軟件價格、三十米跨度的立交橋，不管用鋼還是預應力砼，通常的做法是用一根等截面梁跨越，但由于人們的視覺有錯覺，鋼橋深化設計軟件價格，所以往往把這根梁看成是帶下垂撓度的彎梁，看起來很不舒服，甚至有怕它掉下來的危險。我們在貴陽市中心環(huán)南線朝陽洞路—玉廠路立交橋方案設計中，有意把梁底線作成反拱線，在橋墩支點處稍微增加一點材料，但給橋下車輛和行人一種安全美的感覺。實際上呈反拱的下弦就等于是一根弧形托梁，這是一種簡單的支承，它融合在梁體內(nèi)，變得看不出，可它能起到美化橋梁的作用。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="鋼橋深化設計軟件價格" src="https://tyunfile.71360.com/UploadFile/QYBM3926/637280895694189453/9842770.png"></div><p style="text-indent:25px">鋼橋小知識：鋼橋是一種橋跨結構用鋼材建造的橋梁。1874年美國在密西西比河上建造了世界上一座大型鋼橋——圣路易斯(St.Louis)鋼拱橋，第二次世界大戰(zhàn)以后，鋼橋科學技術在**質(zhì)量鋼的冶煉，焊接技術的提高，正交異性鋼橋面板和**螺栓的應用，以及結構型式的多樣化等方面，有了很大的發(fā)展，促使大跨度鋼橋的普遍采用。由于鋼材強度高，性能優(yōu)越，表觀密度與容許應力之比值小，故鋼橋跨越能力較大。鋼橋的構件制造適合工業(yè)化，運輸與安裝均較方便，架設工期較短，破壞后易修復和更換，但鋼材易銹蝕，養(yǎng)護困難。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="鋼橋深化設計軟件價格" src="https://tyunfile.71360.com/UploadFile/QYBM3926/637280895469238282/7258924.png"></div><p style="text-indent:25px">合理的鋼橋結構體系應該是剛柔相濟的。結構太剛則變形能力差，強大的破壞力瞬間襲來時，需要承受的力很大，容易造成局部受損后全部毀壞；而太柔的結構雖然可以很好的消減外力，但容易造成變形過大而無法使用甚至全體傾覆。結構是剛多一點好，還是柔多一點好？剛到什么程度或柔到什么程度才算合適呢？這些問題歷來都是**們爭論的焦點，現(xiàn)今的規(guī)范給出的也只是一些控制的指標，但無法提供“放之四海皆準”的精確答案。后，**們達成難以準確言傳的共識：剛柔相濟乃是設計者的追求。也許都是相通的。</p></p><br
