Thesis (M.Eng.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2003.<br>Includes bibliographical references (p. 59-62).<br>Recent earthquakes, starting with the 1971 San Fernando Earthquake in California, left major destructions, damaged the infrastructure, and raised questions about the vulnerability and design practice of structures, especially concrete structures. Design codes have being updated to include seismic previsions but structures build before 1971 have to be retrofitted. The focus of this paper is concrete structures. Surveys done after earth

Abstract:

An investigation is presented of the behavior of time-reversal focusing in soils. Initial numerical models demonstrate time-reversal focusing to be effective in elastic media, including when a large number of scattering objects were present in the medium. When scattering objects are present, time-reversal focusing demonstrates superior focusing ability when compared to other excitation methods such as uniform excitation or time-delay focusing. Multiple experimental investigations of experimental time-reversal focusing performed in sand evaluate time-reversal focusing effectiveness when mult

Abstract:

Multiple methods exist for modeling with synthetic seismograms, each with its own characteristic application; local and detailed; global and asymptotic; body and/or surface waves. Events such as the nuclear tests in the Tarim Basin in China, recorded at regional distances require more than one such characteristic. A successful model would need detail close in and a global result. The ability to join two methods can therefore be very powerful. Within this text the exploration is of finite difference and discrete wavenumber integration methods. The basis of the conversion between methods is the

Wood-framed buildings have generally performed well during earthquake events, resulting in low fatality levels. However, various degrees of damage is still observed in these buildings during previous earthquakes. Lessons learned from the performance of wood frame construction in these earthquakes is led to an improvement in the design codes and construction practices over the past decades. But, the existing buildings are still vulnerable, since they were designed based on the older codes or constructed using old construction practices.

Abstract:

The refraction convolution section (RCS) is a simple and efficient method for full trace processing of shallow seismic refraction data. It facilitates improved interpretation of shallow seismic refraction data through the convenient use of amplitudes as well as traveltimes. The RCS is generated by the convolution of forward and reverse shot records. The convolution operation effectively adds the first arrival traveltimes of each pair of forward and reverse traces and produces a measure of the depth to the refracting interface in units of time which is equivalent to the time-depth function of t

Reinforced concrete bridge columns built prior to 1971 cannot withstand earthquake forces due to insufficient transverse reinforcement, poor detailing, and lap-splices in the plastic hinge area.

Experimental research as well as field experience has shown that there are a significant number of technologies that are effective column retrofit solutions for the thousands of bridges worldwide that are in need of upgrade.

Unreinforced masonry construction is considered to be the most vulnerable forms of construction as demonstrated through recent earthquakes. In Canada, many densely populated cities such as (Vancouver, Montreal and Ottawa) have large inventories of seismically vulnerable masonry structures. Although measures have been taken to rehabilitate and increase the seismic resistance of important and historic structures, many existing unreinforced masonry structures have not been retrofitted and remain at risk in the event of a large magnitude earthquake.

Modern acquisition of seismic data on receiver networks worldwide produces an increasing amount of continuous wavefield recordings.

Various machine learning algorithms, which can be adapted to seismological problems, have been suggested in the field of pattern recognition. This can be done either by means of supervised learning using manually defined training data or by unsupervised clustering and visualization. The latter

Abstract:

La conception des bâtiments selon le code sismique européen ne prend pas en compte les effets de l'interaction sol-structure (ISS). L'objectif de cette recherche est de proposer une technique de modélisation pour prendre en compte l’ISS et l'interaction structure-sol-structure (ISSS). L'approche de propagation unidirectionnelle d’une onde à trois composantes (1D-3C) est adoptée pour résoudre la réponse dynamique du sol. La technique de modélisation de propagation unidirectionnelle d'une onde à trois composantes est étendue pour des analyses d'ISS et ISSS. Un sol tridimensionnel (3D) est modéli

Abstract:

L'analyse sismique des structures de génie civil est une problématique majeure pour la sécurité des personnes et la pérennité des ouvrages. L'étude expérimentale permet de comprendre le comportement réel de la structure mais occasionne des problèmes de coût important et d'effet d'échelle souvent inévitable dû aux dimensions des structures. D'un autre côté, l'étude numérique propose une bonne approximation du comportement global mais la représentation précise des phénomènes locaux (fissuration, perte de matière, flambement, grands déplacements) dans les zones fortement endommagées est délicate
