Reinforcing method to improve seismic performance of reinforced concrete school buildings
The present invention relates to a reinforcing method for improving seismic performance of a reinforced concrete school building. The reinforcing method for improving seismic performance of a reinforced concrete school building includes: a step (a) of performing structure evaluation of a waist wall (10) which is a masonry wall; and a step (b) of performing reinforcement by using non-contraction mortar and a square pipe (23) on a column (20) adjacent to the waist wall (10) evaluated by corresponding an evaluated grade when a structure is evaluated as one grade of a reinforced object in accordance with an evaluation result of the step (a). The evaluation result of the step (a) is classified into a reinforced object and an unreinforced object, and the reinforced object is classified into a first grade, a second grade, and a third grade. When the reinforced object is the first grade, the square pipe (23) is anchored to three sides of the column (20) of a school building. Also, the non-contraction mortar is injected into the square pipe. When the reinforced object is the second grade, the square pipe (23) is anchored to the two sides of the column (20) in the school building. Also, the non-contraction mortar is injected into the square pipe. When the reinforced object is the third grade, the square pipe (23) is anchored to the one side of the column (20) in the school building. Also, the non-contraction mortar is injected into the square pipe.
본 발명은 철근콘크리트 학교 건축물의 내진 성능 향상을 위한 보강 방법으로서, (a) 조적벽인 허리벽(10)의 구조 평가를 수행하는 단계; 및 (b) 상기 (a)의 평가 결과에 따라 보강 대상 중 어느 하나의 등급으로 평가된 경우, 평가된 등급에 상응하여, 평가된 허리벽(10)에 인접한 기둥(20)에 대하여 각관(23) 및 무수축 몰탈을 이용하여 보강을 수행하는 단계를 포함하며, 상기 (a) 단계의 평가 결과는 보강 대상, 보강 미대상으로 구분되고, 보강 대상은 제1급, 제2급 및 제3급으로 구분되며, 보강 대상이 제1급인 경우 학교 건축물의 기둥(20)의 3면에 각관(23)을 앵커링하고 무수축 몰탈을 각관에 투입하고, 보강 대상이 제2급인 경우 학교 건축물의 기둥(20)의 2면에 각관(23)을 앵커링하고 무수축 몰탈을 각관에 투입하고, 보강 대상이 제3급인 경우 학교 건축물의 기둥(20)의 1면에 각관(23)을 앵커링하고 무수축 몰탈을 각관에 투입하는, 보강 방법을 제공한다.
