EXPERIMENTAL STUDY ON FULL PRECAST CONCRETE BEAMS WITH SPLICE - BAR JOINTS OF LONGITUDINAL BARS AT THE MIDSPAN

Abstract

In this study, flexure and shear tests were conducted to clarify the structural performance of reinforced concrete beams formed by joining together two full precast beam-end elements at the mid-span using grout mortar with splice-bar joints of longitudinal bars. A total of seven specimens were used in the tests. The parameters were the strength of the longitudinal bars, the transverse reinforcement spacing, and the length of the lap splices. This study revealed that current evaluation formulas can be used under the proposed full precast joint system to evaluate the bond splitting strength of the lap splices.
