Shear test on hollow-core slabs that using board-type lightweight materials is performed. Lightweight materials are positioned in the slabs, it separate into two parts vertically. It is possible that each parts act independently and the concrete columns, in the middle of slab, can resist this action. Thus we have to check horizontal shear force on part-column connection besides vertical shear force. Also effective cross-sectional area shear force which is considered by existing study is checked.
