International Journal of Natural Disasters, Accidents and Civil Infrastructure / Revista Internacional de Desastres Naturales, Accidentes e Infraestructura Civil

The scope of this publication covers engineering systems that provide support and help in the design of civil infrastructure, and to the natural disasters and accidents caused by human which may affect the infrastructure. The journal emphasizes contributions which address one or more of the areas identified in the title. The term infrastructure refers here to the physical facilities which allow moving or storing products, raw materials, water, solid waste, energy, information or people. This includes bridges, ports, canals, airports, railroads, systems of urban traffic, roads, lifelines, energy transportation, pipelines, dams, water treatment plants, tanks, silos, and others. Emphasis on natural disaster is placed on hurricanes, tornados, earthquakes, floods, drafts, fire, landslides, and others. The journal also deals with man-made accidents, such as design or construction errors, explosions, impacts with vehicles, and others.

El alcance de esta publicación comprende los sistemas de ingeniería que dan apoyo y sirven para el diseño de la infraestructura civil, y a los desastres naturales y accidentes de origen humano que pueden afectar esa infraestructura. La revista publica contribuciones que se refieran a la conjunción de más de una de las áreas temáticas definidas en el título, o a una de ellas. El término infraestructura civil se usa aquí para designar al conjunto de instalaciones físicas que permiten movilizar o almacenar bienes, materias primas, agua, residuos, energía, información o personas. En general, se incluyen aquí puentes, puertos, canales, aeropuertos, ferrocarriles, sistemas de tránsito urbano, carreteras, líneas de comunicación y energía, tuberías, represas, plantas de tratamiento de aguas, tanques, silos, etc. El énfasis en desastres naturales está en el estudio de acciones de huracanes, tornados, terremotos, inundaciones, sequías, fuego, deslizamientos, y otros. Asimismo la revista publica temas relacionados con accidentes y eventos producidos por causas humanas, incluyendo fallas por diseño o construcción, colisiones con vehículos, explosiones, entre otras.

ESTUDIO DE LA INFLUENCIA DE LAS IRREGULARIDADES EN PLANTA EN LA RESPUESTA SÍSMICA DE UNA ESTRUCTURA DE CONCRETO ARMADO
L. Pérez Peña, G. Doz

International Journal of Natural Disasters, Accidents and Civil Infrastructure (Online first).

Abstract
The changes in the geometry of the structures are called irregularities and are divided into two types: plant and height irregularities, the latter being widely investigated. In this sense, the objective of the present work is to study in detail the influence of the plant irregularities in the seismic resistance of a reinforced concrete structure, to quantify and locate vulnerable zones in the structure. The proposed study is developed numerically using ETABS software Nonlinear v9.7.2 and MATLAB R2009b. The results showed that plant irregularities as they are placed in the structure, this is losing its bearing capacity and therefore its ability to withstand the lateral loads.

VELOCIDADES DE VIENTO EXTREMAS EN EL NORDESTE DE ARGENTINA
B. Natalini, M. Natalini

International Journal of Natural Disasters, Accidents and Civil Infrastructure (Online first).

Abstract
The extreme wind map of the Argentinean code of practice CIRSOC 102 was updated in 1997 from records of the period 1967-1990. The information contained in this map is represented by the Basic Wind Speed, '''V'''. The contribution of the uncertainty of '''V '''to the whole uncertainty of the design wind load, of either a building or structure, is dominant with regard to the other variables that make up the wind load. Some authors asses this contribution to be above 70%, which underlines the importance of having good quality estimations of '''V'''. For this reason the extreme wind maps are updated periodically. In this work, results of '''V''' calculated from updated records of seven meteorological stations in north-eastern Argentina (NEA region) are presented. The values turn out to be noticeably lower than those of the CIRSOC 102; a reduction that is magnified when evaluated in terms of resulting wind loads. The records have been previously depurated after a combined assessment of both the quality of the instrumentation and the completeness of every yearly record. 95% confidence limits are presented, being the first time confidence limits are published for Argentina. Further values of '''V '''obtained after consolidating data of some stations in superstations are presented. Reductions of the confidence limits ranging 30% to 50% were observed.

DYNAMIC BUCKLING OF SHELL-LIKE STRUCTURES UNDER PRESSURES DUE TO AN EXPLOSION
M. Ameijeiras, L. Godoy

International Journal of Natural Disasters, Accidents and Civil Infrastructure (Online first).

Abstract
The nonlinear dynamic response and buckling of a simple, two degree of freedom system is investigated in this work under an impulsive load that simulates a nearby detonation-like explosion. The system includes force and moment springs in much the same way as membrane and bending effects develop in shell structures. The static response is first obtained to evaluate bifurcation states and nonlinear equilibrium paths including geometric imperfections. The dynamic problem is modeled using Lagrange equation of motion. The nonlinear dynamic response under impulsive load is next computed for the perfect configuration under increasing load levels. The presence of quasi-bifurcations is detected using stability coefficients based on second order derivatives of the total potential energy. For a given load level, it is found that one stability coefficient vanishes at the first maximum in the displacement versus time trajectory, at which the system passes through a state of zero velocity. This occurs for the same displacement configuration as in the static buckling mode. The results show that quasi-bifurcation loads thus obtained are independent of the amplitude of the geometric imperfection considered but display high sensitivity to changes in the membrane to bending stiffness ratio.
