Abstract


Dynamic problems analysis in the field of construction is necessary to guarantee the reliability of the structures in different applications, especially in case of structures subjected to seismic solicitations. In that context, the interest of this work is to study the effects of the composite materials used in the bracing concept for a building by using displacement dimensioning methods and establishing the “Pushover method” fragility curves. For this reason, a set of reinforced concrete buildings designed accordingly to the usual seismic practices, is used to study the influence of the bracing based on the innovative plates (FRP) compared to the one of the reinforced concrete sail which is based on the stability of the work during an earthquake. From one hand, the assumption of adherence is considered perfect between the FRP strips and the concrete, and on the other hand, between the reinforcements and the concrete, which makes it possible to analyze efficiently the behavior of the mechanical response of the proposed variants in this study. The aim is to improve the understanding of bracing in case of reinforced concrete construction in quasi-static (Pushover) and dynamic regimes. Several seismic numerical simulations based on the tool of massive finite elements have been conducted in order to identify the interest of different variants through the indicators’ evaluation of partial and total degradation of the superstructure. The study of the influence of each design variant on the stability of the construction has ultimately clarified the role of a new bracing proposal developed based on FRP materials.
