Scaling unreinforced masonry for reduced-scale seismic testing
When testing multi-storey structures, most testing facilities require the testing of a reduced-scale model. A literature review on tests of scaled masonry structural components revealed that scaling of masonry was rather challenging and often significant differences in stiffness, strength and failure mechanisms between the different sized masonry were reported. This paper addresses the scaling ...
متن کاملDamage Accumulation in Unreinforced Masonry Due to Seismic Loading
Masonry has low cohesive strength and is susceptible to the brittle failure, when subjected to induced tensile stresses. It fails due to lateral tensile stresses even when masonry prisms are tested in uni-axial static compression and the stress-strain curve remains almost linear up to failure. Although masonry normally resists compressive forces, under lateral in-plane cyclic loads some parts o...
متن کاملTowards Displacement-Based Seismic Design of Modern Unreinforced Masonry Structures
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...
متن کاملSeismic Design of Box-Type Unreinforced Masonry Buildings Through Direct Displacement-Based Approach
In the last decade, displacement-based seismic design procedures have been recognised to be effective alternatives to force-based design (FBD) methods. Indeed, displacement based design (DBD) may allow the structural engineer to get more realistic predictions of local and global deformations of the structure, and hence damage, under design earthquakes. This facilitates the achievement of perfor...
متن کاملSeismic Mitigation of a Historic Masonry Building
This work presents an analysis of different proposals of rehabilitation of a masonry building, built around the beginning of the XX century for public schools, in the highest seismic risk zone of Argentine; and which was closed down after Mendoza`s Earthquake in 1985. The building has masonry walls of artisanal ceramic bricks and wood-framed roof but it does not have lateral ties. Currently, it...
