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.

两层预制钢筋混凝土建筑物的抗震性能评估

在预制建筑中，标准混凝土构件是在受控环境中制造的，然后进行现场安装。一种这样的预制系统是3S建筑系统（强度，安全性和速度），它由带有凹口的RCC空心柱组成；RCC实心梁（“ T”形/“ L”形/方形），RCC楼梯，RCC剪力墙和高压釜加气混凝土（AAC）或RCC预制板。当前的研究集中在该系统的抗震性能上，在该系统中，一栋全尺寸的两层“ 3S”预制RC建筑物承受了准静态侧向荷载。实验结果表明，该结构在生命安全（LS）性能水平下的弹性范围内做出响应，并且对关节的损害最小。将结果进一步与经过推入分析的SAP2000中的分析模型进行比较。实验和分析结果均一致。因此，可以推断3S建筑系统在地震荷载下可以令人满意地运行。
