영어
The objective of this investigation is to study the elasto-plastic behavior of hybrid beams using precast ductile fiber reinforced cementitious composites(DFRCCs) from-work and normal concrete subjected to vertical load. The hybrid beam, which DFRCCs is filled with concrete, expected to raises durability of concrete. For comparison, DFRCCs beams using PolyVinyl
Alcohol fibers and Polypropylene fibers, and general reinforced concrete beam are tested. The length of specimens is 1920mm, the section is 170x270(mm), the thickness of the DFRCCs form is 35mm, the main bar is D13, the tie bar is D6. The research results clearly showed that the proposed hybrid beam showed stable hysterisis behaviors than general concrete beam.
