Resilience Observatory

Reinforced Concrete Building Databases

Detailed surveys and inspections of reinforced concrete structures affected by the earthquakes in Nepal were conducted in a reconnaissance effort funded by The American Concrete Institute. The effort was concentrated on identification of buildings with structures similar to new and older reinforced concrete buildings in seismic areas in the U.S. The reconnaissance group consisted of 4 teams with 3 or 4 people in each team. Data were collected between June 18, 2015 and July 01, 2015.
Database on Performance of High-Rise Reinforced Concrete Buildings in the 2015 Nepal Earthquake
By Prateek Shah, Santiago Pujol, and Aishwarya Puranam from Purdue University
This database contains information on 30 high-rise reinforced concrete buildings with 8 to 17 stories above ground. Building plans, drawings, photographs and GPS coordinates were collected for buildings that were inspected. Structural drawings and models were also collected for some of the inspected buildings.
By Prateek Shah, Santiago Pujol, Aishwarya Puranam, and Lucas Laughery from Purdue University.
This database contains information on 146 low-rise reinforced concrete buildings with and without masonry infill walls inspected in Kathmandu, Nepal. Building plans, dimensions, photographs and GPS coordinates were collected for buildings that were inspected.
