초록
The weight of concrete could be reduced by using hollow core slabs instead of heavy solid slabs, leading to costreduction. The long span be also achieved by introducing prestress in hollow core slabs. but the evaluation of shear strength ofprecast-prestressed hollow core slabs are needed because the cross section is reduced in web and arranging shear reinforcement is notpossible. In this study, the shear strength of precast-prestressed hollow core slabs were evaluated based on experimental tests. For this purpose, six full scale specimens were made and tested. The shear strength of the specimens were compared with those evaluated from current design provision(EC2 ACI, EN1168 and AASHTO).
