Seismic Evaluation of Retrofitting Technique Using Bracing Systems for Steel Multi-Story Building [PDF]

BIO Web of Conferences
A bracing system is the one of effective retrofitting methods for existing high buildings to support the lateral loads. Structural bracings increase the stiffness and stability of the building and the energy dissipation capacity.

Impact of inadequate column performance and repair techniques on the seismic performance of RC buildings

Discover Civil Engineering
Nepal lies in a seismically active zone, and recent earthquakes, such as the Gorkha (2015) and Jajarkot (2023) earthquakes, have caused the failure of many reinforced concrete (RC) frame structures.

Retrofitting aged masonry buildings using advanced cementitious fibre reinforced concrete material: case study and comparison to traditional methods

Sustainable Buildings
China has a large stock of existing aged buildings that can no longer meet the needs of modern life and need to be reinforced to improve their seismic resistance. Complete demolishing and rebuilding waste resources while retrofitting and reusing are more

SEISMIC RETROFITTING OF AN EXISTING STRUCTURE

International Journal of Research in Engineering and Technology, 2015
Retrofitting an existing building is often considered to be more cost-effective than constructing a new building. It represents an opportunity to upgrade the overall performance, sustainability and efficiency of an existing building. Seismic retrofitting is mainly done to provide existing structures with more resistance to seismic activity due to ...
