ratio）、撓度（deflection）和鋼橋的寬跨比保證橋梁的剛度。4、疲勞（fatigue）：構件和連接的疲勞強度受材質(zhì)、連接方法與方式、荷載性質(zhì)、應力狀態(tài)，廣州好的鋼橋設計服務企業(yè)、應力幅和應力比的影響。5、連接（connection）：鋼橋構件一般由鋼板和型鋼等焊接而成，廣州好的鋼橋設計服務企業(yè)，用**螺栓(high-strength

style="text-indent:25px">設計中，交通組織功能也要擺在重要的地位上，尤其是立交橋，不光橋上有車輛，橋下車輛也川流不息。如果不綜合考慮交通功能，下行車輛撞擊橋墩或有關橋梁部分，導致橋梁坍塌，這種事件在國內(nèi)外都有發(fā)生。作為橋梁設計人員必須注意這一點來進行橋梁方案比選，乃至方案確定后的橋梁分跨。在貴陽市都司路高架橋跨越中華路的大南門交叉口位置，設計者在地面設置了交通導流環(huán)島，一跨20米跨徑的橋梁正好處于環(huán)島內(nèi)。橋梁建成后，隨著城市的發(fā)展，車輛的增多，該交叉口經(jīng)常塞車，不得已取消了地面環(huán)島。由于該交叉口的橋梁跨徑較小，導致左轉車輛的行車軌跡不順暢，司機抱怨連天，這無疑是橋梁設計敗筆。 </p><p style="text-indent:25px">加勁肋設置：加勁肋是在支座或有集中荷載處，為保證構件局部穩(wěn)定并傳遞集中力所設置的條狀加強件。加勁肋的設置是因為原有構件截面的不足而用來增強抵抗彎矩和剪力的，因為設置加勁肋可以縮小原構件截面大小，從而有效的降低用鋼量，壓縮成本，所以在工程中，一般設置在原有構件上起到增強抵抗彎矩和剪力的作用。施工人孔的設置：橋梁的整體設計中，其不可忽視的一環(huán)是人孔的設置。通常情況下，人孔是為了方便施工，在橋梁箱梁頂板和腹板上開設。頂板施工人孔的具**置可設置在1.5跨徑處，而腹板的施工人孔的具**置必須設置在應力相對薄弱的地方結構內(nèi)力計算結構內(nèi)力計算是以邊孔采用單懸臂，中孔采用簡支掛梁作為結構的計算模式。鋼橋設計的時候要具有必要的橫向剛度。</p><div

style="text-indent:25px">鋼橋小知識：如果鋼橋的設計和養(yǎng)護不當，將嚴重影響鋼橋的耐久性和使用壽由于未栓合或未焊合的接觸部分的層間緊密度不能保證，容易形成細縫吸水，不易干燥，為了防止鋼梁銹蝕，鋼梁結構中不應有未栓合或未焊合的接觸部分。鋼梁構件上的小坑和凹槽容易引起積水，應該避免。同時，對于箱形結構或有可能積水的部位，應該開泄水孔等，防止由于空氣結露、漏水等原因導致積水。對于開口截面形式，應盡可能避免容易積水和灰塵堆積的構造細節(jié)。鋼橋在安裝或檢修支座時，常需將梁頂起，故在結構上應預設可供頂起作用的結構（如在千斤頂支撐處預設加勁肋、牛腿或在連續(xù)梁的中間支點處設置可供頂起用的結構等）?？紤]到頂起時受力的不均勻及其他偶然因素，頂起結構應按實有重量超載30％驗算。在布置千斤頂位置時，需要考慮更換支座等必須的操作空間。鋼橋的優(yōu)點是材料的運輸量少。廣州好的鋼橋設計哪家好</p><p style="text-indent:25px">舊鋼橋可回收，資源可再利用，有利于環(huán)保。廣州好的鋼橋設計服務企業(yè)</p><p style="text-indent:25px">鋼橋小知識：鋼橋設計不僅要滿足使用階段的受力和工作性能要求，而且應分析施工吊裝和調(diào)整支座等受力狀況，使鋼橋在施工過程中滿足應力和變形的要求。考慮到吊裝過程中的慣性作用和其他不可預見的不利因素影響，公路鋼橋規(guī)范規(guī)定，鋼橋施工驗算時起頂設備及結構本身都應按起頂重力增加30％驗算。鋼橋的一缺點是疲勞。影響鋼橋疲勞的主要因素有：鋼材品質(zhì)、荷載性質(zhì)、應力狀態(tài)、連接的構造與方法、構造細節(jié)等。鋼橋的設計必須選用有足夠韌性的鋼材，盡可能避免應力集中和容易出現(xiàn)疲勞的構造細節(jié)、連接構造與方法。結構在其傳力途徑中的截面變化的緩急程度是影響應力集中的主要因素，鋼橋設計中應該避免截面的急劇變化。如T形連接中盡可能設置曲線過渡段，避免出現(xiàn)隅角。廣州好的鋼橋設計服務企業(yè)</p><p
