In precast construction, standardized concrete elements are manufactured in a controlled environment followed by onsite installations. One such precast system is 3S building system (Strength, Safety, and Speed), which consists of RCC hollow columns with notches; RCC solid beams (“T” shape/“L” shape/Square Shape), RCC Stair flights, RCC shear walls, and Autoclave Aerated Concrete (AAC) or RCC precast slab. The current study focuses on seismic performance of this system, where a full‐scale two storey, “3S” precast RC building, was subjected to quasi‐static lateral loading. The experimental results show that the structure responded within elastic range at Life Safety (LS) performance level with minimal damage to the joints. The results are further compared to an analytical model in SAP2000 subjected to pushover analysis. Both the experimental and analytical results were found to be in agreement. Therefore, it is inferred that the 3S building system can perform satisfactorily under seismic loads.
