An Experimental Study of SL Shear Reinforcement for Reinforced Concrete Flat Plate Slab
철근콘크리트 무량판 슬래브의 일체형 SL(Shear Ladder) 전단보강재에 관한 실험적 연구
Abstract
This study is concerned with the SL shear reinforcement that it can be installed easily in filed as product at the factory and seismic performance can be achieved. The method of study is as follows. first, we researched constructability and economy of existing method. Secondly, we made specimen and were examined structural performance tests in order to verify the performance of the shear reinforcement. Shear strength of HILL01-HILL03 specimen applied to SL shear reinforcement increased about 5-14% when compared with the applied shear stirrup reinforcing existing specimens. Also, the amount of the maximum deflection of the central sub-section of HILL01-HILL03 specimen applied to SL shear reinforcement decreased about 41-42% when compared with the applied shear stirrup reinforcing existing specimens. As a result, developed SL shear reinforcement increased in shear strength and stiffness of reinforcement, structural safety is judged to be increased.
