Alameda Tubes seismic retrofit studies

Computers & Structures, 1999
Abstract As a part of the Posey and Webster Street Tubes seismic retrofit project, finite element analysis was used to study the soil–structure interaction behavior due to earthquake ground motions. This paper summarizes the nonlinear analysis activities for the Alameda Tubes.

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 Retrofit of Adobe Constructions

2017
Earthen construction has been widely used since ancient times. Currently, this type of construction is used by approximately one third of the world population. In comparison to other, more modern building materials, such as brick masonry, reinforced concrete, and steel, earth is costless and primarily accessible. For these reasons, it is massively used

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 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 ...

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 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 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.
