SERFIN : Seismic retrofitting of RC frames with RC infilling

The effectiveness of seismic retrofitting of multi-storey multi-bay RC-frame buildings by converting selected bays into new walls through infilling with reinforced concrete (RC) was studied experimentally at the ELSA facility of the Joint Research Centre in Ispra (Italy). A full scale model was tested with the pseudo-dynamic method and consisted of two four-storey (12m tall) three-bay (8.5m long) parallel frames linked through 0.15m slabs with the central bay (2.5m) infilled with a RC wall. The frames were designed and detailed for gravity loads only and are typical of similar frames built in Cyprus in the 1970’s. Different connection details and reinforcement percentages for the two infilled frames were used in order to study their effects in determining structural response. The dataset gathers the data acquired during the experimental campaign giving an insight on the seismic response of the retrofitted frame.

本研究针对多层多跨钢筋混凝土（Reinforced Concrete, RC）框架建筑的抗震加固有效性展开实验探究，通过将选定跨间填充钢筋混凝土（RC）墙体转化为新增墙体的方式开展相关试验，实验地点位于意大利伊斯普拉的联合研究中心（Joint Research Centre）ELSA设施。本次试验采用拟动力法对足尺模型进行加载测试，该模型包含两榀四层（高12米）、三跨（长8.5米）的平行框架，框架通过厚度0.15米的楼板相连，其中间跨（跨度2.5米）填充有RC墙体。该类框架仅按重力荷载进行设计与配筋构造，是1970年代塞浦路斯地区同类建成框架的典型代表，试验针对两榀填充框架采用了不同的连接构造细节与配筋率以探究其对结构响应的影响规律，本数据集收录了本次试验全过程采集的全部试验数据，可为深入解析加固后框架的抗震响应特性提供支撑。
