FINITE ELEMENT MODELING AND UPDATING OF A FIVE-TIERED PAGODA STYLE TEMPLE
Advisor: Dr. Richard L. Wood
Historical pagoda style temples demonstrate different dynamic behavior than traditional unreinforced masonry (URM) structures due to the unique construction practices and ornate architecture detailing. Understanding their seismic vulnerability and structural behavior can lead to more efficient retrofit solutions and conservation practices for similar heritage structures. Recently, the 2015 Gorkha Mw 7.8 earthquake resulted in widespread structural damage and collapse of similar historic temples in Nepal. However, one example did not collapse. This is the five-tiered Pagoda style Nyatapola temple built in 1702 and located in Bhaktapur, Nepal. This study developed and calibrated the pre-and post-earthquake finite element (FE) models of this temple based on post-earthquake reconnaissance efforts using lidar data, visual damage assessment, and ambient vibration test results. A detailed linear time history analysis is conducted to simulate the seismic demands during the 2015 event, and give insight into the performance of pagoda style temples for future seismic events. The study recommends that torsional retrofitting schemes may be able to reduce future damage on these heritage structures.
