Pre - stress steel structure , a new type of structure in which combine pre - stressed with steel structure . adding some high strength bar in steel structure , and forcing these bars pre - stress can improve the structure capability , reduce the structure weight 预应力钢结构是一种将预应力与钢结构相结合的新型结构,就是在钢结构中增加某些高强度杆件,并且对这些杆件施加预应力,使其达到改善结构性能,降低结构自重等作用。
Compared with steel structure , preflex composite structure has the advantages of not only saving steel but also being able to strengthen rigidity of structure members and the whole structure . in addition it has better characteristics in fireproof and antirust . compared with reinforced concrete structure , it has a lighter structure weight , higher strength , higher bearing capacity and better ductility as well 与钢结构相比,它不但节省钢材,而且能够增强构件及建筑物的刚度,防火和防锈性能好;与钢筋混凝土结构相比,它不但重量较轻,而且具有较高的强度、承载力和良好的延性,能充分发挥钢和混凝土两种不同材料的受拉受压特性。
