style="text-indent:25px">鋼橋設(shè)計(jì)一般要求和原則：鋼橋在安裝或檢修支座時(shí)，常需將梁頂起，故在結(jié)構(gòu)上應(yīng)預(yù)設(shè)可供頂起作用的結(jié)構(gòu)（如在千斤頂支撐處預(yù)設(shè)加勁肋、牛腿或在連續(xù)梁的中間支點(diǎn)處設(shè)置可供頂起用的結(jié)構(gòu)等）。考慮到頂起時(shí)受力的不均勻及其他偶然因素，頂起結(jié)構(gòu)應(yīng)按實(shí)有重量超載30％驗(yàn)算。在布置千斤頂位置時(shí)，需要考慮更換支座等必須的操作空間。由于鋼板厚度可能有軋制負(fù)公差，且在長(zhǎng)期運(yùn)營(yíng)過(guò)程中會(huì)產(chǎn)生銹蝕現(xiàn)象，因此對(duì)構(gòu)件應(yīng)規(guī)定鋼板和型鋼的較小厚度。節(jié)點(diǎn)板位于幾根桿件交匯的部位，弦桿與腹桿的內(nèi)力是通過(guò)節(jié)點(diǎn)板來(lái)傳遞的，因此節(jié)點(diǎn)板應(yīng)力狀態(tài)比較復(fù)雜，既有壓應(yīng)力，也有拉應(yīng)力，還有剪應(yīng)力，應(yīng)力分布也極不均勻。焊接板梁為保證腹板穩(wěn)定和減小殘余應(yīng)力，板厚均不宜過(guò)小，故規(guī)定以不小于10mm為宜。對(duì)于主梁、行車系或聯(lián)結(jié)系，因考慮可能采用有懸伸翼緣的I形或T形構(gòu)件，從滿足較小寬厚比的要求出發(fā)，規(guī)定以不小于8mm為宜。填板為非受力構(gòu)件，規(guī)定不小于4mm。</p><p
