Application of Steel-concrete Reinforcement Technology in Strengthening Endangered Old Bridge
With the rapid development of domestic economic construction and the increasing traffic volume,some bridges can not adapt to the existing load level due to the early construction age,and then become dangerous bridges,which seriously affects the safety of driving.Therefore,the reinforcement technology of dangerous old bridg-es has become a topic that needs further research in the current engineering field,and it is urgent to explore effec-tive reinforcement programs.Steel-concrete reinforcement technology can give full play to the tensile properties of steel and concrete,and has the advantages of greatly improving the bearing capacity and stiffness of bridges,improv-ing the structural force,increasing the durability,etc.,and has broad application prospects.This article through the calculation and analysis of reinforced concrete T beam reinforced by steel-concrete combination,the bearing capac-ity of bridge before and after reinforcement is compared,which provides a new idea for bridge reinforcement.
