Within the strengthening techniques of masonry elements with Fiber Reinforced Plastic (FRP) materials, the use of FRP grid applied with cement based mortar seems to be very promising and interesting, mainly due to the compatibility of the mortar with the m ...
In Switzerland many new residential buildings are designed as mixed structures with unreinforced masonry (URM) walls and reinforced concrete (RC) walls while existing URM structures are often retrofitted by replacing selected URM walls by RC walls. The lat ...
In several seismic countries, residential buildings are constructed using both reinforced concrete (RC) and unreinforced masonry (URM) walls. Despite their popularity, there is a general lack of knowledge concerning the seismic behaviour of such mixed syst ...
In this paper we report the detection of explosive compounds using a miniaturized gas preconcentrator (μGP) made of porous silicon (PS) filled in with Carbopack B as an adsorbent material. The μGP includes also a platinum heater patterned at the backside a ...
Many older unreinforced masonry (URM) buildings feature timber floors and solid brick masonry. Simple equivalent frame models can help predicting the expected failure mechanism and estimating the strength of a URM wall. When modelling a URM wall with an eq ...
In this paper we use the novel Disturbed Stress Field Model (DSFM) from Facconi et al. (2013) to model the lateral in-plane behaviour of different unreinforced masonry (URM) walls which we tested at the laboratory of the EPF Lausanne, Switzerland. The mode ...
A systematic study of the properties of high-density amorphous ice (HDA) in the presence of increasing amounts of salt is missing, especially because it is challenging to avoid ice crystallization upon cooling the pressurized liquid. In order to be able to ...
In codes the drift capacity of unreinforced masonry (URM) walls is often estimated as a function of the failure mode and the aspect ratio. The empirical relationships are based on results from quasi-static cyclic tests on single URM walls, which were teste ...
The performance of fibre reinforced plastic (FRP) materials used for external strengthening depends strongly on the bond behaviour at the FRP-substrate interface. In this paper, the results of an analytical model and of two Finite Element (FE) models (bi-a ...
The strengthening method characterized by the application of composite grid reinforced mortar layers onto the surface of masonry walls is a quite new technique and, thus, still requires deep experimental and numerical investigation. This strengthening tech ...
