ABSTRACT:
On 25 April 2015, the Gorkha earthquake of magnitude 7.8, severely damaged the cultural heritage sites of Nepal. In particular, the seven monument zones of the Kathmandu Valley World Heritage Site suffered extensive damage. Out of 195 surveyed monuments, 38 have completely collapsed and 157 partially damaged (DoA, 2015). In particular, the world historic city of Bhaktapur was heavily affected by the earthquake. There is, in general, a lack of knowledge regarding the traditional construction...”

1. INTRODUCTION
1.1 Scope and Objective of Research
As a result of the Gorkha earthquake in Nepal on April 25, 2015, and the aftershock that followed on May 12, a large number of heritage structures in Nepal were destroyed or significantly damaged. In particular, the seven monument zones of the Kathmandu Valley World Heritage Site suffered extensive damage. Out of 195 surveyed monuments, 38 have completely collapsed and 157 were partially damaged (DoA, 2015). Bhaktapur, in particular, is a recognized UNESCO World Heritage Site (WHS) containing many structures of significant cultural and religious importance to the people of the Kathmandu Valley. Sustainable reconstruction and restoration of these heritage structures are critical to maintaining and restoring their outstanding value. To achieve this goal, it is important to work with local experts, engineers, and architects to understand the traditional construction technology and existing...”

2.1 FieldWork
In this study, the authors collaborated with local institutions and professionals to conduct field work and build local capacity to do similar work in future. The focused project location for this study is Taumadhi Square in the Bhaktapur World Heritage Site (WHS). At the north end of the square is the five-tiered temple with a square footprint called the Nyatapola Temple. This temple is the tallest in Nepal and was constructed in 1701/1702 AD by King Bhupatindra Malla. Since its construction, this structure has resisted three major earthquakes (Mw 8.0 in 1833, Mw 8.4 in 1934...”

“...buildings in Bhaktapur, Nepal which suffered damage in the 2015 earthquake. The outcome of research addresses the important difficulties related to the preparation of existing condition drawings, acquisition of data on material properties, internal morphology and damage, and determination of structural load paths.
In this study, an existing methodology for digital recording is implemented for recording heritage structure of Kathmandu Valley and comparative studies were made. This will contribute towards adaptation of the sustainable recording methodology suitable for the Kathmandu Valley Heritage.
Furthermore, uncertainty related with timber structure inside wall and construction typology of high rise plinth is also studied using georadar, a non-destructive technique. This will provide a base for understanding the internal morphology of masonry wall and study a relationship between the superstructure and plinth and its effect in the performance of superstructure during a seismic event.
This...”
