Seismic intervention options for multi-tiered Nepalese Pagodas: The case study of Jaisedewal temple

Abstract During the 2015 Gorkha earthquake of 7.8 Mw that hit Kathmandu Valley, Nepal, numerous Nepalese Pagodas suffered extensive damage while others collapsed. Risk reduction strategies implemented in region focused on disassembling historical structures and rebuilding them with modern material without depth analysis why they suffer collapse. The aim this paper is to evaluate effectiveness low-cost, low-intervention, reversible repair strengthening options for Pagodas. As a case study, Jaisedewal Temple, typical example architectural style, was investigated. A nonlinear three-dimensional finite element model Temple developed seismic performance temple assessed by undertaking linear, static dynamic analyses. Also, different structural intervention options, suggested local engineers architects working restoration temples were examined their efficacy withstand strong vibrations. Additionally, response exposed foundation are sitting From results analysis, it found pushover failed capture type failure which highlights necessity perform time-history accurately investigated temple. stiffening connections along enhance behaviour temple, plinth base concluded be insignificant. Outputs from research could contribute towards strategic planning conservation multi-tiered across Nepal reduce risk future seriously affecting beautiful heritage.
