Abstract

This study aims to develop the precast concrete (PC) beam-to-column joint in a 3-story building where A-type PC column is used. A-type PC column was developed to replace a pre-engineered building system suitable for warehouses and factories. To create a spacious interior, a 3-story PC structure with a central span of approximately 10m was analyzed; the beam members and the column members were designed based on design codes. Then, two types of PC beam-column joints with mechanical anchors, often called headed bars, were developed. These joints could be constructed easily and rapidly using mechanical anchors; connecting plates made of SM45C and high strength bolts for splicing longitudinal rebars were placed inside the U-shell beam. Although the proposed PC beam-column joints exhibited a similar strength to the monolithic joint, it also showed the failure mode of weak column-strong beam, a common structural behavior in small buildings. Particularly, the PC joint using high tension bolts were determined for special moment frames according to ACI 374.1-05.
