چکیده

Vehicular crashes into buildings seem to be an on-going problem with severe consequences. When the building is of masonry, damage at impact zone more possible intrusion vehicle building, depending on velocity impact. In all these cases, vibration propagated from wall edges and then adjoining walls in can result their damage. While has been studied, propagation impacted potential for have not treated. Dynamic response masonry due caused by vehicular impacts important global safety assessment structures. With this mind, paper presents a numerical study vibration-induced characteristics structures subjected impacts. A homogenised material model incorporating strain rate effects suitable applications using layered shell elements adopted research improved computational efficiency. The induced studied through models various types validated deformable employed predict HIC (Head Injury Criteria) evaluate head injury risk occupants when it structure. outcomes demonstrated that unreinforced collision low velocities compared high-velocity Moreover, value calculated impacting 100 km/hr 23.5, which considerably lower than tolerance limit 1000. This desirable feature vehicle, significant amount energy absorbed transmission across wall.

Effective 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...

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...

Flexural 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...

Limit 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...

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...
