薄層モルタル厚さおよびモルタル強度が頭付きスタッドのせん断耐力に及ぼす影響に関する実験的研究

抄録

In this study, we focused on the thin mortar layer applied to adjust the height between the Precast PC slab and the steel girder. We fabricated specimens with parameters such as the thickness of the thin mortar layer and the mortar strength, and discussed the effect on the stud shearing force by push-out test. It was proven that crack was generated in the thin mortar layer by the working of bending in addition to shearing force, when there is the thin mortar layer, and that stud shearing force lowers. Therefore, it is necessary to propose a new design formula for the stud shearing force when there is the thin mortar layer between the Precast PC slabs and the steel girders.
