중공 PC기둥을 사용한 플랫 플레이트 슬래브-기둥 접합부의 전단보강

Recently, Construction Business, is changing very quickly, exceedingly needs to slim down the expensive by material costs and term of works. Because of that reason, new technologies of construction studies are very popular. It is part of a Shell PC column. Therefore, intend of study was to investigate the response of column-slab connection of Shell PC column and flat plate slab that has been widely used in high rise buildings. Shear reinforcement methods of column-slab connection joint are two types of stud rail and shear band. Three test specimens are consisted of RC column-slab connection joint shear band(RC-24-B) as reinforcement and Shell PC column-slab connection joint shear band (PC-24-B) and stud rail (RC-24-S) as reinforcement, respectively. The load of test is preformed to combined gravity and cyclic lateral loading. The test results showed that the strength and ductility of the RC-24-B and PC-24-B with the shear band as reinforcement were improved more than PC-24-S with stud rail as reinforcement.
