La presente investigación propone un procedimiento general de análisis para edificios altos sobre la base de los requerimientos de la Norma Peruana E.030. Primero, se realiza la configuración estructural de los edificios, se define el número de edificios y la cantidad de niveles, así como el sistema estructural predominante. Luego, se definen las características de los materiales, las cargas y las combinaciones. Los casos de estudio que se desarrollan se basan en edificaciones altas peruanas existentes como el Hotel Westin Libertador y el Banco de la Nación. Para la configuración estructural se utilizó el sistema estructural de núcleo rígido debido a su gran versatilidad y funcionalidad. Después, se describen los métodos de análisis de estructuras altas y se procede con el análisis de la verificación de derivas y realizar una comparación de la cortante en la base mediante el análisis estático, análisis dinámico modal espectral y análisis lineal tiempo historia. Para el análisis tiempo historia se empleó 5 registros peruanos espectro compatible, mientras que para el diseño de las placas de concreto armado se usó el análisis modal espectral. / Abstract. Currently, there is an increase in the demand for tall buildings in the city of Lima. This research proposes to reduce the dynamic amplification factor through the seismic design of tall buildings based on the requirements of Peruvian code considering that they are regular in plan and height. Mini-mum base shear values according to the comparison of static seismic shear and dynamic shear from spectral modal analysis were reviewed for cases of buildings larger than 120 meters. The study of 28 reinforced concrete build-ings was proposed, with different heights - varying from 24 to 36 floors, with different floor configurations, as well as the arrangement of the walls considering as a rigid core structural system. Additionally, the characteristics of the materials, the loads and combinations were defined. The responses of these buildings were determined by the response spectrum analysis (RSA) and then compared with those obtained by the lineal response history analy-sis (LRHA), for the last analysis, five Peruvian seismic records were used and scaled to 0.45g. The seismic responses of the LRHA procedure were taken as benchmark. The result of this study is the analysis and proposal of the C / R factor for high-rise buildings, as well as obtaining the base shear and drift verification. Minimum base shear values can be reduced for high or long-term buildings, being regular in plan and height. / Trabajo de investigación

Entre los años 1992 – 2002, el Instituto Nacional de Infraestructura Educativa y Salud (INFES), ahora PRONIED realizó construcciones masivas de unidades escolares entre los cuales se encuentra el módulo tipo Apenkai, las cuales se diseñaron con los criterios de la norma de aquella época. Si bien se siguió el proceso de diseño adecuado, en la actualidad se sabe que antes se subestimaban los parámetros para el análisis estructural, dando como resultado edificaciones con poca rigidez. Como Perú está ubicado en una zona de alto riesgo sísmico y sobre todo las ciudades de la costa como Lima, en la cual no se ha registrado un movimiento telúrico de magnitud importante en más de 40 años, se debe estar preparado para un pronto acontecimiento. Es indispensable que los colegios resistan sismos severos, ya que estos sirven como refugio ante este tipo de desastres. Por ello, debido a que la inversión en el rubro educativo en el país es muy poca, no hay posibilidad de demoler las estructuras antiguas para construir modernas, en esta tesis se planteara estructurar y diseñar propuestas de reforzamiento para los colegios antes mencionados. Además, se elaborará un análisis de costos de las propuestas para determinar la más económica, la cual se puede a las características de otras zonas. Como punto de partida, se siguieron los estudios previos realizados por las tesis de los ingenieros Antonio Blanco y Henry Núñez en las que realizan evaluaciones estructurales de distintos colegios y plantean posibles soluciones. Esta tesis se enfocará en un colegio llamado I.E.I. “3048 – Santiago Antúnez de Mayolo, ubicado en Lima, ciudad donde se concentra la mayor cantidad de edificaciones de este tipo. Para la tesis se propuso separar la estructura en dos bloques y aplicar métodos de reforzamiento: encamisados, aletas, placas de concreto armado y arriostre de acero. / Between 1992 and 2002, the National Institute of Educational Infrastructure and Health (INFES), now PRONIED, carried out massive constructions of school units, including the Apenkai type module, which were designed according to the criteria of the norm of that time. While the proper design process was followed, it is now known that previously the parameters for structural analysis were underestimated, resulting in buildings with little rigidity. As Peru is located in an area of ​​high seismic risk and above all the cities of the coast as Lima, which has not recorded a major earthquake in more than 40 years, must be prepared for an early event. It is essential that schools resist severe earthquakes, as these serve as a refuge from this type of disaster. Therefore, because the investment in education in the country is very small, there is no possibility of demolishing the old structures to build modern, in this thesis will propose to structure and design proposals for strengthening for the aforementioned schools. In addition, cost analysis of proposals will be developed to determine the most economical, which can be applied to the characteristics of other areas. As a starting point, the previous studies carried out by the theses of the engineers Antonio Blanco and Henry Nuñez in which they carry out structural evaluations of different schools and propose possible solutions were followed. This thesis will focus on a school called I.E.I. "3048 - Santiago Antúnez de Mayolo, located in Lima, city where the largest number of buildings of this type is concentrated. Among the proposals for reinforcement will be the use of reinforced concrete casings and reinforced concrete slabs. / Tesis

Les phases de conception et de validation de pièces mécaniques nécessitent des outils de calculs rapides et fiables, permettant de faire des choix technologiques en un temps court. Dans ce cadre, il n'est pas possible de calculer la réponse exacte pour l'ensemble des configurations envisageables. Les métamodèles sont alors couramment utilisés mais nécessitent un grand nombre de réponses, notamment dans le cas où celles-ci sont non-linéaires. Une solution est alors d'exploiter plusieurs sources de données de qualité diverses pour générer un métamodèle multi-fidélité plus rapide à calculer pour une précision équivalente. Ces données multi-fidélité peuvent être extraites de modèles réduits.Les travaux présentés proposent une méthode de génération de métamodèles multi-fidélité pour l'optimisation de structures mécaniques par la mise en place d'une stratégie d'enrichissement adaptatif des informations sur la réponse de la structure, par utilisation de données issues d'un solveur LATIN-PGD permettant de générer des données de qualités adaptées, et d'accélérer le calcul par la réutilisation des données précédemment calculées. Un grand nombre de données basse-fidélité sont calculées avant un enrichissement intelligent par des données haute-fidélité.Ce manuscrit présente les contributions aux métamodèles multi-fidélité et deux approches de la méthode LATIN-PGD avec la mise en place d'une stratégie multi-paramétrique pour le réemploi des données précédemment calculées. Une implémentation parallèle des méthodes a permis de tester la méthode sur trois cas-tests, pour des gains pouvant aller jusqu'à 37x. / Engineering simulation provides the best design products by allowing many design options to be quickly explored and tested, but fast-time-to-results requirement remains a critical factor to meet aggressive time-to-market requirements. In this context, using high-fidelity direct resolution solver is not suitable for (virtual) charts generation for engineering design and optimization.Metamodels are commonly considered to explore design options without computing every possibility, but if the behavior is nonlinear, a large amount of data is still required. A possibility is to use further data sources to generate a multi-fidelity surrogate model by using model reduction. Model reduction techniques constitute one of the tools to bypass the limited calculation budget by seeking a solution to a problem on a reduced order basis (ROB).The purpose of the present work is an online method for generating a multi-fidelity metamodel nourished by calculating the quantity of interest from the basis generated on-the-fly with the LATIN-PGD framework for elasto-viscoplastic problems. Low-fidelity fields are obtained by stopping the solver before convergence, and high-fidelity information is obtained with converged solution. In addition, the solver ability to reuse information from previously calculated PGD basis is exploited.This manuscript presents the contributions to multi-fidelity metamodels and the LATIN-PGD method with the implementation of a multi-parametric strategy. This coupling strategy was tested on three test cases for calculation time savings of more than 37x.

abstract: One of the fundamental aspects of cellular material design is cell shape selection. Of particular interest is how this selection can be made in the context of a realistic three-dimensional structure. Towards this goal, this work studied the stiffness response of periodic and stochastic lattice structures for the loading conditions of bending, torsion and tension/compression using commercially available lattice design optimization software. The goal of this computational study was to examine the feasibility of developing a ranking order based on minimum compliance or maximum stiffness for enabling cell selection. A study of stochastic shapes with different seeds was also performed. Experimental compression testing was also performed to validate a sample space of the simulations. The findings of this study suggest that under certain circumstances, stochastic shapes have the potential to generate the highest stiffness-to-weight ratio in the test environments considered. / Dissertation/Thesis / Masters Thesis Mechanical Engineering 2019

The present doctoral thesis engages in an internal environment of wooden buildings. Currently, the specialists endeavour to design and realize this type of buildings as low-energy consuming. In an effort, they minimize the thermal losses by reduction of heat transfer coefficient of external walls and reduction or elimination of their air permeability. Not always structural and technical requirements of this kind of buildings are satisfied and also a sanitary and health protection is not fully sustained. Increase in a relative air humidity of internal environment has a negative impact on moisture in wood and heat insulation in the structure. Then the buildings are exposed to the increased risk of mold infestation. This can cause various health problems such as headache, respiratory diseases, general fatigue or impaired concentration. For the purpose of experimental verification of the internal environment, four wooden houses of medium size were observed in 2010 and 2011. The internal temperature and humidity as well as subjective feelings of the household members were monitored there. For the simulation of the real wooden construction, an application BSim was used. Different states as well as stationary and nonstationary physical processes were simulated by the boundary conditions adjustment. Also the criteria for designing and optimization of living comfort of household members were recommended in the thesis.

The aim of the diploma thesis is to design and assessment of the steel structure of shopping mall, which is situated in Brno. Three variants were processed, from which one was selected for more detailed processing. Variants have hexagonal floor plan with maximum dimension 60,0 m, four floors and same structural solution. They differ in plan of secondary beams and columns, in floor plan of glass atrium and used cross-sections. Building´s load-bearing structure consists of pin-supported columns, primary beams, secondary beams and purlins. Rigidity of the structure is enshured by system of vertical bracings and in horizontal direction by composite slab. The structure elements are made of steel S355, except secondary beams, which are made of steel S235.
