RESUMO

El objetivo de este trabajo, es estudiar el efecto de la no-linealidad del suelo de fundación en el desarrollo de las fuerzas y desplazamientos que se producen en las fundaciones de grupos de pilotes, para estructuras de puentes y compararlos con modelos que consideran lineal la interacción suelo-pilote (ISP). Para este trabajo se escogió un puente existente y se modeló considerando que estaba soportado en cinco perfiles de suelos diferentes, los cuales variaban desde rígidos a blandos. También se incluyó la alternativa de usar gruos de pilotes verticales o grupos de pilotes inclinados. De esta forma, diez fundaciones diferentes fueron diseñadas; cinco para grupos de pilotes verticales y cinco para grupos de pilotes inclinados. Para la metodología que considera interacción suelo-pilote (ISP) lineal, se establecieron basados en consideraciones no lineales, límetes de desplazamientos horizontales y cargas máximas laterales para el pilote, así como para cada una de las fundaciones diseñadas. Estos límites, determinan el máximo desplazamiento o carga lateral en el pilote (o fundación) para la cual las metodologías que consideran ISP lineal, producen desplazamientos horizontales conservadores en el pilote (o fundación). dichos límites, van a depender entre otros factores, de la rigidez del suelo y de si los pilotes en las fundaciones se encuentran en posición vertical o inclinados. Comparaciones entre las fuerzas desarrolladas en los pilotes que conforman la fundación, para las cargas de diseño, se obtuvieron mediante consideraciones de ISP lineal y no lineal. Se encontró que siempre que no se excedió el límite de la metodología (LM), los resultados usando ISP lineal fueron conservadores al estimar los desplazamientos y las fuerzas en los pilotes diseñados(AU)

RESUMO

Roads, railways and coastlines are all large scale linear features usually incorporating many earthworks. These earthworks are subject to deterioration and may fail causing serious problems. A significant number of these failures could be prevented if all earthworks were monitored frequently and early signs of deterioration nated so that improvements could bemade. Inspections on food, however, are verry costly and time consuming and therefore are rarely undertaken, on a frequent basis. A technique, known as ECAT, to monitor earthworks and provide information for their repair has been developed at the Transport Research Laboratory (TRL). The analysis procedure employed is designed to be used on linear features, when many earhqworks have to be evaluated quickly and inexpensively, and concise information about their location and cause of deterioration is required. The technique used to record earthworks and a description of the analysis procedure is provided, with an example showing the results of the analysis. (AU)

RESUMO

Se presentan los resultados de la respuesta sísmica de un edificio instrumentado, de cuatro niveles cuyo sistema estructural está resuelto a base de muros de mampostería, desplantado en zona del Lago de la Ciudad de México. Se ana;lizan los acelerogramas obtenidos en el edificio de tres sismos, por medio de técnicas de identificación de sistemas. Se estudian las implicaciones del comportamiento observado en el diseño por cargas laterales de estas estructuras. Se muestra que el uso de una variación de bargas laterales de tipo triangular invertido como las que consideran los reglamentos de diseño, puede favorecer la concentración de deformaciones inelásticas en la parte inferior de la estructura. Finalmente se recomienda que para movimientos de terreno con espectros de banda angosta caracterizados por un periódo predominante significativamente más largo que el periódo fundamental de la estructura, se empleé una distribución uniforme de fuerzas laterales para su diseño.(AU)

RESUMO

comparison and combination of high - resolution Digital Elevation Models and ortho - images generated from multi - date stereo photogrammetric aerial views, provides a powerful tool for the study of large ground movements, e.g. landslides and creep. Several sites have been studies in France; for each, a digitised image of the deformation field of a continuous ground surface has been computed, The extraction of qualitative and quantitative data, such as displacement and the volume of superficial deformetion, provides the necessary data for characterising and understanding the evolution of such sites.

RESUMO

The purpose of this study is to understand the mechanical properties of liquefied sand to estimate the behevior of ground after liquefaction and to investigate the mechanism of occurrence of liquefaction-induced large ground displacement. In this paper we consider that the mechanical properties of liquefied sand can be separated the following two phases, (1) the fluid characteristic of liquefied sand as viscous fluid, (2) the solid characteristic of liquefied sand under large deformation.(AU)

RESUMO

A method which evaluates soil-structure interaction effects is presented. The method consists of an equivalent oscillator which includes the effects of the interaction, modifying its original fundamental period and damping. The new oscillator is treated like a replacement oscillator in the system with rigid base. The response contours concept displays the site effects and the soil-structure interaction at the same time, in terms of both the dominant site period and the fundamental structural one. Response contours profiles depict response spectra with soil-structure interaction at different sites. Response contours are evaluated for different sites and different structure configurations, typical of Mexico city. Results of parametric analyses illustrate the importance of key parameters in soil-structure interaction effects, such as the depth of soil deposit, the embedment of the foundation and the slenderness of the structure.(AU)

RESUMO

The development if the structure of land use in this city is analyzed since its creation up to now. Three well-defined stages are distinguished separated by two fundamental events: 1) the March 20, 1861, earthquake which stands out from the rest because it was the most destructive one in Argentina, destroying the city of Mendoza and killing 6,000 people out of a population of 18,000; and 2) the sudden urban growth in the 1950s which unified small surrounding urban centres with the original one, establishing the base of the presente city called Gran Mendoza with 800,000 inhabitants. The seismic hazard estimation was carried out considering the following aspects: seismicity, potential seismic sources, attenuation relations and local soil conditions , thus maximum acceleration maps with 10


probability of exceedance were obtained for different ranges of time.(AU)

RESUMO

In examining the safety of structures it is commonly assumed that, once an earthquake loading had been defined, the reliability that can be attributed to the resulting structural design is identical with, or similar to that for a design for gravity loading. As the design processes differ in many ways it is difficult to see how this can be so. It is also apparent that the specification of load does not take into account uncertainties in the structural design process and modify the earthquake loading in order to make some compensation, as this loading is commonly defined without participation of structural engineers. A study of the significant parameters is presented.(AU)

RESUMO

Se presentan los resultados de la aplicación del método, que fue desarrollado por I. Herrera y E. Rosenblueth (1965), para el análisis del movimiento sísmico, que se propaga a través de suelos estratificados y modelado como un proceso gaussiano estacionario, mediante la -- Transformada de Fourier. Se propone una expresión lineal, que relaciona al coeficiente de amplificación del movimiento sísmico con el del amortiguamiento elasto-viscoso, en el caso de suelos constituidos por un solo estrato homogéneo (AU)
