외부긴장재로 보강된 2경간 연속 강합성보의 초기 긴장력 결정

Determination of the Initial Tendon Forece in Two-span continuous Steel-Concrete Composite Beam Strengthened with External Tendons

초록

This paper presents a method to enhance the load carrying capacity for a two-span continuous steel-concrete composite beam strengthened with external tendons. The tendon is placed at the bottom of steel beam where the positive bending moment occurs. This results in the reduction of the negative bending moment as well as the positive bending moment. This paper describes the procedure to determine the number of tendon and the initial tendon force for the target rating factor in the rating factor equation. An example beam is given to demonstrate the proposed procedure, and it validity is confirmed
