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 of the McIlraith Bridge

IABSE Reports, 2017
<p>The McIlraith Bridge is a 202 m long six-span variable depth steel plate girder structure located in Ottawa, Ontario, with in-span joints in each girder at the second span from each end separating the structure into three segments. The seismic evaluation and retrofit design was completed to the newly adopted CSA S6-14 and based on the Seismic ...

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 Fragavilla Monastery

Earthquakes and Structures, 2013
Practical seismic assessment and design of retrofit for the multitude of small ecclesiastical monuments that abound in the Balkans is the subject of this work. Application of the proposed procedures and methodologies are illustrated in an example case study, a small byzantine church located in Western Greece, which is the region with the highest ...

Global Seismic Retrofit Techniques

A selection of some the most common ‘global’ seismic retrofit techniques are discussed in detail. These include the addition of concrete walls, steel frames, supplemental damping devices, base isolation, and removing mass and irregularities. The basis of each technique is described, and then conceptual design examples are provided to support the reader

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 ...

The seismic evaluation and retrofitting of bridges

1996
Past earthquakes have clearly shown the seismic vulnerability of existing bridges. Despite recent progress by the structural engineering profession in addressing bridge seismic risks, there are still several areas where improvements in bridge evaluation and retrofit practices are needed.
