鋼結構工程的加固措施

鋼結構工程是以鋼材制作為主的結構，主要由型鋼和鋼板等制成的鋼梁、鋼柱、鋼桁架等構件組成，各構件或部件之間通常采用焊縫、螺栓或鉚釘連接，是主要的建筑結構類型之一。因其自重較輕，且施工簡便，廣泛應用于大型廠房、橋梁、場館、超高層等領域。

鋼結構工程

鋼結構工程加固的主要措施有：
(1)減輕荷載、改變鋼結構設計圖形、加大原結構構件截面和連接強度、阻止鋼結構鏈接裂紋擴展等不利條件的產(chǎn)生。當有成熟經(jīng)驗時，也可采用其他的加固方法。經(jīng)鑒定需要加固的鋼結構工程，根據(jù)損害范圍一般分為局部加固和全面加固。
(2)局部加固是對某承載能力不足的桿件或連接節(jié)點處進行加固，有增加桿件截面法、減小桿件自由長度法和連接節(jié)點加固法。
(3)全面加固是對整體結構進行加固，有不改變結構靜力計算圖形加固法和改變結構靜力計算圖形加固法兩類。
(4)增加或加強支撐體系，也是對結構體系加固的有效方法。
(5)增加原有構件截面的加固方法是最費料最費工的方法(但往往是可行的方法);改變計算簡圖的方法最有效且多種多樣，其費用也大大下降!
