Compte tenu des attentes en termes de développements durables, de nouvelles solutions technologiques sont adoptées dans les bâtiments à basse consommation énergétique permettant de réduire considérablement les déperditions par ponts thermiques. Il s’agit des rupteurs thermiques, nouvelles jonctions entre porteurs verticaux et horizontaux constituées de matériaux innovants. Parallèlement à l’évolution des réglementations thermiques dans les bâtiments, la nouvelle définition de l’aléa sismique en France oblige les concepteurs à intégrer le cas de chargement sismique dans les dimensionnements de bâtiments dans une grande majorité du territoire métropolitain. Ces innovations technologiques nécessitent donc des études approfondies de leur comportement mécanique lors d’événements accidentels tels que les tremblements de terre. Au regard des enjeux sociétaux et économiques, il est d’une grande importance d’être capable d’apprécier la contribution de nouvelles solutions techniques à la vulnérabilité du bâti aux séismes. Pour cela, il est nécessaire de procéder à des analyses probabilistes pour la construction, par exemple de courbes de fragilité de structures sous sollicitations sismiques: structures étant composées ou non de rupteurs thermiques. L’objectif de ce travail est donc de proposer l’ensemble d’une méthodologie notamment les outils numériques, en termes de modèles mécaniques, susceptibles de répondre aux attentes de l’ingénierie dans la quantification de l’évolution des marges de résistance en intégrant différents types de rupteurs thermiques dans les bâtiments. Pour cela, différentes étapes, combinant modélisations numériques et expérimentations sont abordées afin d’élaborer un modèle numérique simplifié. Ce dernier doit être riche en termes de phénomènes mécaniques et efficace numériquement pour réaliser rapidement un nombre important de calculs nonlinéaires à l’échelle de bâtiment en tenant compte des aspects aléatoires. / Nowadays sustainable constructions imply an objective of energetic performances by reducing the level of thermal conduction. The thermal-break elements, an innovative technological element is under study in several countries in Europe. If the thermal benefits have already been proved, the mechanical effects of such a wall-slab connection in a building for the seismic risk have not been assessed. To evaluate the building seismic vulnerability modifications due to these thermal breaks, experimental and numerical developments have to be performed. An experimental campaign is proposed to evaluate the seismic ability of such structural elements and a simplified modelling is proposed aiming at developing numerical framework able to handle parametrical and probabilistic approaches for structural analysis. This model is also validated in dynamic case by using the Pseudodynamic testing.

The aim of this work is a static analysis of the reinforced concrete frame structure loaded by the effects of seismic loading. The work deals with the solution of multi-storey reinforced concrete structure designed for common loading conditions and further for possibilities of strengthening of the structure on effect of seismic loading. In the first phase of the work, the static analysis and the design of the main load-bearing elements of the frame structure (columns and main girder) were carried out for the ultimate limit state for the standard design load. In the second phase, the static analysis of the structure for the effects of accidental actions from low and high seismicity was performed and it was assessed whether the main load-bearing elements of the structure would continue to comply. Given that the structure did not satisfy the accidental actions of seismic loading, various ways of structure strengthening were designed and analyzed for their impact on the global and local behaviour of the structure. Also the designing of additional steps for structural reliability were performed. Static analyzes were performed in Scia Engineering and RFEM Dlubal software.

In this diploma thesis the seismic load on two different models is solved – the first model is a beam hall and the second model is a multistory building. The calculation of seismic load was performed according to standard ČSN EN 1998-1 (Eurocode 8) using the response spectrum analysis and the method of equivalent static forces (substi-tute load). For the combination of seismic responses in different directions are used SRSS and CQC rules. Models and calculations were solved in a student’s version of program RFEM 4.10 (Ing. Software Dlubal, s.r.o.). The comparison of mentioned methods in each models, also the comparison of combinative rules in calculation and the final evaluation of seismic responses on both of models are the subject of this thesis.
