Damage 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 کاملScaling 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 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 کاملLimit states of modern unreinforced clay brick masonry walls subjected to in-plane loading
Recent research showed that the in-plane horizontal displacement capacity of unreinforced masonry (URM) walls depends on numerous factors that are not yet captured by current empirical drift capacity models; e.g., axial stress, shear span, geometry of the walls and the material used. In order to improve the performance-based assessment of URM wall buildings, future research should aim at develo...
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...
