Decision support model for seismic strengthening technology selection of masonry buildings

Original scientific paper When the decision has been made to seismically strengthen a building, in order to mitigate possible damaging effects of an earthquake, choice of seismic strengthening is entirely left to the expert. The choice is often made without any specific analyses of the need and implementation possibilities, but depends completely on the expert's knowledge and experience. The article presents the development of the innovative approach to strengthening technique selection for existing buildings that incorporates all important elements that influence the strengthening selection process. The presented model is simple, quick, precise, allowing analytically supported decision making. Although the developed model is designed particularly for masonry buildings, decision support model for strengthening technique selection is adaptable to any building type. Keywords: decision support model; existing buildings; innovative approach; masonry; seismic strengthening technology Metodologija odabira tehnologije seizmičkog ojačanja zidanih zgradaIzvorni znanstveni članak Kada je donesena odluka o potrebi za ojačanjem zgrade u cilju preventivne zaštite od potresa, kao pravilom, odabir ojačanja prepušten je stručnjaku. Odabir ojačanja se najčešće provodi bez konkretnih analiza mogućnosti i potreba za određenim pothvatom, već isključivo prema nahođenju i prošlom iskustvu stručnjaka. U članku se predstavlja proces razvoja inovativnog pristupa izboru tehnologija ojačanja postojećih zgrada, a kojim se uzimaju u obzir svi bitni elementi koji mogu utjecati na izbor ojačanja. Predstavljeni model je jednostavan, brz i precizan, te dozvoljava donošenje odluka na osnovu analitički dokazanih činjenica. Unatoč tomu što je model izrađen isključivo samo za zidane zgrade, model za izradu potpore odlučivanja pri odabiru tehnologije ojačanja je prilagodljiv bilo kojem tipu građevina.Ključne riječi: inovativan pristup; model za odabir tehnologije; postojeće zgrade; tehnologije seizmičkih ojačanja; ziđe

“…Strengthening masonry structures with FRP is a common actuation among the conservation and maintenance tasks carried out on the masonry buildings which require structural strengthening (see [11,12]). Although the drawbacks of this system (water vapour impermeability and insufficient mechanical compatibility with the masonry), which have been pointed out by several authors (see, for example the work by Baratta et al [13], or the articles by Papanicolaou et al [14,15]), FRP is still used for strengthening masonry structures because of its outstanding performance (justified in works like [11,12]) and the existence of consolidated guides and standards like [16,17].…”

In relation with the performance of the FRP, this strengthening technology is specially indicated for those interventions which require limiting the lateral deflection of the walls and look for a stiffer out-of-plane response of the structure.…”

Fibre Reinforced Polymers laminates are currently used to strengthen brick masonry walls. However, no specific evidences of the structural response of this strengthening system when brick walls are subjected to eccentric compressive loads, which might lead to second order bending effects, have been found. An experimental campaign on real-size walls has been carried out and the results have been compared with a numerical model, which predicted the observed shear/compressive masonry failure, and a new analytical approach, which has been used to accurately calculate the load-bearing capacity of the walls. Useful considerations for the strengthening design are also presented.

“…In many developed countries the use of FRP as internal or external reinforcement of concrete structural members and they have their own design guides or standards [3,4]. In some other countries the reinforcement with FRP is used in the recovering of historical buildings after an earthquake, as occurred in Italy [5]. In this paper, it is studied the external reinforcement of damaged beams.…”

Abstract:The knowledge of the behavior of damaged beams is important to predict the behavior of structural members and to know how the structure can be affected by damages. In this work, it is simulated and analyzed experimentally the behavior of reinforced concrete beams after tested up to ultimate limit state (ULS) reinforced by vacuum form glass fiber reinforced polymer (GFRP). Firstly, it is used the finite element analysis (FEA) to compare the experimental results with the simulated ones. Secondly, the same technique is used to generate a (GFRP) profile to reinforce the damaged beam. Finally, the results were compared and discussed.
