Proposed Detailing of Reinforcement to Enhance the Structural Performance in Two-way Slab System

이방향 슬래브의 구조성능 향상을 위한 배근상세의 제안

To overcome the common deficiencies found in such two-way slabs, such as excessive cracking around columns, excessive deflections and low punching shear strength, it was proposed to investigate the strategic reinforcing steel distribution detailings. Concentration of the top mat of flexural reinforcement result in a higher punching shear resistance, higher post cracking stiffness, a more uniform distribution of strains in the top bars and smaller cracks at all levels of loading.
