Texte intégral

Résumé :

Recent geologic research has shown that earthquakes more destructive than formerly expected are likely to occur in the Pacific Northwest. To mitigate catastrophic loss, planners are gathering information to make decision on implementing regional seismic retrofit programs. This research develops a model to estimate regional earthquake losses for existing buildings, and determine optimal retrofit priorities and budgets. Fragility curves are developed to provide earthquake damage estimates for a range of seismic intensities. The published earthquake damage estimates of a large group of prominent

Résumé :

A large magnitude, long duration subduction earthquake is impending in the Pacific Northwest, which lies near the Cascadia Subduction Zone (CSZ). Great subduction zone earthquakes are the largest earthquakes in the world and are the sole source zones that can produce earthquakes greater than M8.5. Additionally, the increased duration of a CSZ earthquake may result in more structural damage than expected. Given such seismic hazard, the assessment of reinforced concrete substructures has become crucial in order to prioritize the bridges that may need to be retrofitted and to maintain the highway

Résumé :

This thesis presents a study into the inelastic earthquake response of asymmetric structures. The study was conducted through the use of numerical simulation and experimental testing. In particular, the study focussed on the effects of the torsional to lateral frequency ratio, the stiffness eccentricity and strength eccentricity on structural response. Previous studies into this area have often drawn contradictory conclusions regarding the effects of the various input parameters on structural response. It was concluded that these differences arose from the use of different analytical mo

Résumé :

The investigation described in this thesis represents the first known attempt to develop a simplified method for the seismic design of structures equipped with a novel friction damping system. The system has been shown experimentally to perform very well and is an exciting development in earthquake resistant design. The design of a building equipped with the friction damping system is achieved by determining the optimum slip load distribution to minimize structural response.

Throughout history, objects of art have been damaged and sometimes destroyed in earthquakes.

Résumé :

Investigations of connections for precast concrete panel buildings have shown that it is difficult to design an embedded connection that will perform well under earthquake loading. Some typical connections use studs or reinforcing bars embedded in the edge of the panel. These are then welded or bolted to an adjacent panel. During earthquake loading the crushing of concrete around the embedment usually leads to premature loss of strength and stiffness of the connection before significant ductility can develop. It has been found that connection performance improves with increasing panel thicknes

Small amounts of cementation in a sand increase its ability to sustain static and dynamic loads, even in a liquefaction type environment. This has been shown in previous research examining the behavior of both naturally cemented and artificially prepared samples. Cemented sands are present in many parts of the world and can be caused by either a variety of cementing agents or by cold welding at points of grain contact. They are generally quite difficult to sample, but artificially cemented sands have been shown to aptly model the behavior of natural materials, and allow for better test contr

Résumé :

The purpose of this paper is to analyze the macroeconomic effects of the earthquake that struck Chile in 2010 and the impact it had on the Chilean economy. It is a narrative case study of a small, open emerging economy and the timeframe is short term. Like other studies made about macroeconomic effects of a natural disaster, it is surprising to find how fast a country can so rapidly recover from a big devastation like the Chilean earthquake 2010. The final economic impact depends on the structural conditions of the economy and the economic policy mix undertaken to handle the short-term effect

An analytical formulation for seismic analysis of multiply supported secondary systems is developed.

The response of the secondary systems is expressed as a combination of the dynamic, pseudo-static and cross response components. The dynamic part is associated with the inertial effect induced by the support accelerations. The pseudo-static part is due to the relative displacement between supports, and the cross part takes into account the correlation between these two

A confined masonry (CM) wall consists of a masonry wall panel surrounded by reinforced concrete (RC) members on its perimeters.

Most of these structures fail in shear pattern under lateral EQ loads, and some of them collapse under a severe or even a moderate EQ due to inappropriate design.

Liquefaction is attributed as a major cause for the loss of strength and stiffness of soil during earthquakes.
