Masonry buildings constitute a significant portion of the architectural heritage all over world, also in regions affected by high seismic hazard. Since this constructional material is characterized lack tensile strength, as well small deformation capacity, masonry structures could result hugely damaged if shaken forces. In order to avoid collapses and reduce structural damage, innovative retrof...

In unreinforced masonry walls, failure due to out -of-plane bending causes the majority of the material damages and loss of human life. Therefore, the development of effective strengthening techniques needs to be addressed. Near-surface mounted (NSM) FRP rods are now emerging as a promising technique for increasing flexural and shear strength of structural members. The aim of this research prog...

nowadays, distinctive methods are used in evaluation of the criteria in order to making decision. among them the analytic hierarchy process (ahp) is one of the most efficient. due to the seismicity of the vast majority part of the country and also the existence of the large number of the unreinforced masonry buildings, the application of the ahp method in order to reach to the best alternative ...

Unreinforced masonry (URM) structures are known to be rather vulnerable to seismic loading. Modern URM buildings with reinforced concrete (RC) slabs might, however, have an acceptable seismic performance for regions of low to moderate seismicity. In particular in countries of moderate seismicity it is often difficult to demonstrate the seismic safety of modern URM buildings by means of force-ba...

Code design of unreinforced masonry (URM) brick buildings is based on elastic analysis, which requires as input, among others, estimates of the in-plane drift capacity at the considered limit states. Current approaches assess the drift capacity of URM walls by means of empirical models with most codes relating the drift capacity to the failure mode and wall slenderness. Comparisons with experim...

Masonry infill has been widely used as building material due to its cost effectiveness and availability.  The failure of these masonry infill walls during the past earthquakes have underscored the importance of ensuring the safety of the infill walls when it is subjected to lateral loads. In-plane and out of plane failures have been observed in many reinforced concrete framed building with maso...

This paper presents a new methodology for generating compression-only vaulted surfaces and networks. The method finds possible funicular solutions under gravitational loading within a defined envelope. Using projective geometry, duality theory and linear optimization, it provides a graphical and intuitive method, adopting the same advantages of techniques such as graphic statics, but offering a...
