Retrofitting of a seismically deficient building

Journal of Structural Integrity and Maintenance, 2016
AbstractMost available seismic retrofitting methods have certain degree of difficulty to be implemented on site and are thus more expensive. A relatively new retrofitting technique coupling the conventional braces with the recently developed viscoelastic dampers is proposed to improve the seismic performance of deficient structures in more effective ...

Seismic Retrofit Design

This chapter covers the key subjects related to the seismic retrofit design process. The difference between global and local retrofit solutions is discussed before highlighting the fact that most projects require a range of intervention techniques. Different conceptual retrofit strategies are then illustrated graphically using the capacity spectrum ...

Seismic Retrofitting of Bridge Foundations

ACI Structural Journal, 1999
An experimental study investigated retrofitting measures for improving the seismic performance of the foundations of existing bridges. Retrofit measures for both pile-supported and spread footings were investigated. Tests were conducted on 1/3-scale footing and column assemblages that incorporated details selected to represent deficiencies common in ...

Seismic Retrofit of Coastal Dikes

Volume 3: Materials Technology; Ocean Engineering; Polar and Arctic Sciences and Technology; Workshops, 2003
Soil liquefaction and associated ground failures have caused much damage to coastal and waterfront structures in the past major earthquakes. The prevalence of liquefaction in the coastal environment necessitates the development of appropriate remediation countermeasures.

Seismic retrofitting of concrete bridges

2006
Bridges which were built before 1970s, either in U. S. or Japan or Europe, had been designed with little or no consideration for seismic demand. Majority of these bridges are supported on reinforced concrete bents and pier walls that lack the ductility and strength to resist earthquakes.

Seismic bridge retrofit in Switzerland

IABSE Reports
<p>In Switzerland, bridges built over the last century were usually designed without considering the effects of earthquakes. As a result, they do not meet the requirements that are placed on new bridges today. Existing bridges are typically reinforced for earthquake resistance only during renovation projects or when they undergo modifications or ...

Seismic retrofitting with cost effectiveness

2012
Located in the heart of Los Angeles, USC is considered an earthquake prone zone, and there is a vital imperative to ensure the safety of all students and faculties during such an event. In order to prevent casualties, buildings must be checked and assured to perform under design loads.
