Low-to-mid-rise building construction using precast concrete structures is becoming popular in Thailand. Manufacturers have developed systems to connect the precast concrete beams and columns. Their focus is mainly on ease of construction and cost-effectiveness. Unfortunately, most of them do not consider safety against seismic load in the design. This study presents a development and design guideline for the systems. With this, two new configurations of intermediate moment frame beam-column connection aiming for moderate seismic area are proposed. The new connections' design emphasizes in sei Authors: Ekkachai,,Yooprasertchai;Anawat,,Chotesuwan;Pongsak,,Wiwatrojanagul;Amorn,,Pimanmas. Presented at TSER2023.
