Testing unreinforced masonry structures at reduced scale
When testing multi-story structures on a shaking table, most testing facilities require a reduced scale model. Producing scale test units at small scale is particularly challenging for unreinforced masonry structures. Previous work by other researchers showed that scaling of units and mortar joints is mandatory in order to obtain for the reduced scale masonry failure modes, which are similar to...
متن کاملFlexural Tension in Unreinforced Masonry
Unreinforced masonry is that in which the tensile strength of the masonry is taken into consideration in design. Allowable out-of-plane tensile stress values are a function of the mortar type, such as Portland cement/lime mortar vs. masonry cement mortar or type M or S mortar vs. type N mortar. The allowable tensile stress is also a function of the masonry construction, such as tension parallel...
متن کاملStudy on Earthquake Damage Distribution of Multistory Masonry Buildings
The main components which affect the earthquake damage grades classification of multistory masonry buildings and the damage characters are summarized and analyzed through the statistics and analysis of a large number of previous earthquake damage data. According to the standard of earthquake damage grades classification, the damage numbers of each component of multistory masonry buildings under...
متن کاملEffective stiffness of unreinforced brick masonry walls
Code design of Unreinforced Masonry (URM) buildings is based on elastic analysis, which requires as input parameter the effective stiffness of URM walls. Current approaches estimate the effective stiffness as fixed ratio of the gross sectional stiffness but comparisons with experimental results have shown that this does not yield satisfactory predictions. In this paper, a recently developed ana...
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...
