style="text-indent:25px">鋼橋是一種橋跨結(jié)構(gòu)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首座大型鋼橋——圣路易斯(St.Louis)鋼拱橋，第二次世界大戰(zhàn)以后，鋼橋科學(xué)技術(shù)在**質(zhì)量鋼的冶煉，焊接技術(shù)的提高，正交異性鋼橋面板和**螺栓的應(yīng)用，以及結(jié)構(gòu)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(qiáng)度高，性能優(yōu)越，表觀密度與容許應(yīng)力之比值小，故鋼橋跨越能力較大。鋼橋的構(gòu)件制造較適合工業(yè)化，運(yùn)輸與安裝均較方便，架設(shè)工期較短，破壞后易修復(fù)和更換，但鋼材易銹蝕，養(yǎng)護(hù)困難。</p><p> 健康鋼結(jié)構(gòu)工程施工所需的設(shè)計(jì)理念： </p> <p> 一是健康鋼結(jié)構(gòu)。健康鋼結(jié)構(gòu)是一種能夠正常、持續(xù)工作并產(chǎn)生良好效益的鋼結(jié)構(gòu)，即能夠承受各種潛在的自然和人為破壞，具有足夠的可靠性（安全性、適用性、耐久性）和良好的社會經(jīng)濟(jì)效益。片面追求經(jīng)濟(jì)效益指標(biāo)的建筑鋼結(jié)構(gòu)，無論其可靠性如何，都必須是有缺陷的、短命的甚至是危險的鋼結(jié)構(gòu)；無論其經(jīng)濟(jì)效益如何片面追求虛幻觀念和怪異形象的建筑鋼結(jié)構(gòu)必然是臃腫浪費(fèi)的鋼結(jié)構(gòu)此外，拼命追求速度，由于設(shè)計(jì)和施工不當(dāng)，缺陷、隱患和昂貴的鋼結(jié)構(gòu)嚴(yán)重影響可靠性，不能認(rèn)為是健康的鋼結(jié)構(gòu)，只能稱之為亞健康、不健康或病態(tài)的鋼結(jié)構(gòu)；只能稱其可靠性和經(jīng)濟(jì)性差的鋼結(jié)構(gòu)。社會效益達(dá)到很好的平衡可以認(rèn)為是健康的鋼結(jié)構(gòu)，比較好的平衡可以稱為不錯的鋼結(jié)構(gòu)建設(shè)一個健康的鋼結(jié)構(gòu)是不容易的，而建設(shè)一個高質(zhì)量的鋼結(jié)構(gòu)則更為困難。只有掌握它的基本性質(zhì)、質(zhì)量和技術(shù)特點(diǎn)，并有相應(yīng)的概念，才能實(shí)現(xiàn)它。在使用期間養(yǎng)護(hù)維修費(fèi)用較省，并且經(jīng)久耐用。</p><div
