The compressive strength of horizontal joints in precast concrete large panel structures depends on parameters such as grout and panel strength, detail of joint, joint moment, width of grout column etc. As the panels are only connected at the pocket, it results in the reduction of compressive strength area. The purposes of this study are to develop the suitable grout material the joint pocket and to enable us to evaluate structural capacity. The validity of the design formulas provides us more economic system in construction. Test results of 15 specimens show that the proper construction procedure and grouting material develop the sufficient compressive strength of the wall as monolithic system.
