Abstract
Seismic Retrofitting of RC Structures with Exterior Shear Walls and Bracing
Highlights
Seismic Retrofitting Techniques are required for concrete constructions which are vulnerable to damage and failures by seismic forces
The aim is to focus on a few specific procedures which may improve the practice for the evaluation of seismic vulnerability of existing reinforced concrete buildings of more importance and fortheirseismicretrofittingbymeansofvariousinnovativetechniqu essuchasbaseisolationandmass reduction
The interest of the research community is focused on buildings that do not comply with current seismic codes and exhibit deficiencies such as poor detailing, discontinuous load paths and lack of capacity design provisions
Summary
Seismic Retrofitting Techniques are required for concrete constructions which are vulnerable to damage and failures by seismic forces. In the past thirty years, moderate to severe earthquakes occurs around the world every year Such events lead to damage to the concrete structures as well as failures. Retrofitting is a collection of mitigation technique for Earthquake engineering It is of utmost importance for historic monuments, areas prone to severe earthquakes and tall or expensive structures.Older construction, designed according to earlier codes, may not comply with current seismic regulations. The engineers make buildings to resist the effects of ground shaking, they may get damaged severely but would not collapse during the strong earthquake. (iii)Under strong but rare shaking, the main members may sustain severe (even irreparable) damage, but the building should not collapse. Upgrading of certain building systems (existing structures) to make them more resistant to seismic activity (earthquake resistance) is really of more importance
