Uttarakhand in the foothills of Himalayas is considered to be one of the most tectonically active regions of northern India as it had experienced several destructive earthquakes such as Pithoragarh (1980), Uttarkashi (1991), Chamoli (1999) and Gopeshwar (2005). The state of Uttar Pradesh (now Uttarakhand) being the center of activity during British regime is having numerous historical brick masonry structures such as churches, missionaries, hospitals, administrative building and educational institutions required to be safeguarded against catastrophic future earthquakes. One such building: Forest Research Institute Dehradun which suffered extensive damages during the Uttarkashi earthquake has been considered for seismic vulnerability assessment and achieving a generalized retrofitting strategy for the region which can be extrapolated globally. Structural assessment by non-linear static analysis has been carried out for FRP retrofitted and an un-retrofitted building using FEM. Different types of FRP has been modeled numerically as wrapped around the piers of huge brick masonry structure and analyzed under site specific earthquake loading which reported in an improved performance of strengthened structure.

使用 FRP 对传统砖砌体建筑进行抗震评估和改造

喜马拉雅山脚下的北阿坎德邦被认为是印度北部构造最活跃的地区之一，因为它经历了几次破坏性地震，如 Pithoragarh (1980)、Uttarkashi (1991)、Chamoli (1999) 和 Gopeshwar (2005)。北方邦（现在的北阿坎德邦）是英国政权期间的活动中心，拥有许多历史悠久的砖石结构，例如教堂、传教士、医院、行政大楼和教育机构，需要保护其免受未来灾难性地震的影响。其中一栋建筑：森林研究所 Dehradun 在 Uttarkashi 地震期间遭受了广泛的破坏，已被考虑进行地震脆弱性评估，并为该地区制定了可以在全球范围内推断的通用改造战略。已经使用 FEM 对 FRP 改造和未改造的建筑物进行了非线性静态分析的结构评估。不同类型的 FRP 已被数值模拟为缠绕在巨大砖砌体结构的桥墩上，并在特定地点的地震载荷下进行了分析，结果表明加固结构的性能有所提高。
