プレストレスを利用して梁に圧着した壁パネルの最大耐力

抄録

This paper deals with an experimental study on the strength of the precast wall panels, which are connected with the upper and lower beams using prestressing, not connected with the columns of the both sides. The experimental parameters are as follows ; magnitude of prestressing, sizes of openings in the center of the wall panel for fastening prestressed concrete (PC) steel bars, joining PC steel bars or not, filling the openings up with PC grout or not, etc. The maximum strength of the wall panel is investigated from some phases as follows; the shear resisting mechanism by cumulating truss mechanism and compressive strut of concrete, moment capacity of the parts sandwiched in the openings, and the slip strength of the horizontal joint published by the authors.
