In this study, a two-phase simplified approach is proposed to predict the in-plane strength capacity of unreinforced masonry (URM) walls. first phase, damage and failure patterns URM walls are determined from available observational (field) data, experimental data also numerical analysis data. Then, set rules estimate wall panels. second valuable information employed develop model with coarse m...

In order to improve the energy dissipation of the masonry infilled frame structure while decreasing the stiffening and strengthening effects of the infill panels, a new dry stacked panel (DSP) semi-interlocking masonry (SIM) infill panel has been developed. In this paper, the material properties of DSP and a traditional unreinforced masonry (URM) panel have been evaluated experimentally. A seri...

Several studies on different techniques can be found retrofitting existing unreinforced masonry (URM) walls using varieties of materials ranging from reinforced plaster, grout and epoxy injectio...

Though flexible diaphragms play a role in the seismic behaviour of unreinforced masonry buildings, effect connections between floors and walls is rarely discussed or explicitly modelled when simulating response such buildings. These are most commonly timber made planks beams, which supported on recesses can slide friction resistance reached. Using equivalent frame models, we capture effects bot...

Given that concrete masonry walls are expected to experience shrinkage combined with thermal expansion and contraction, and in some cases even carbonation, throughout their service life, cracking is to be expected. However, after concrete masonry walls have been placed into service, originally anticipated and accounted for cracking is often misdiagnosed as a structural defect. Such misdiagnoses...

In this paper, earthquake-resistance behaviors of existing masonry structures are evaluated based on a certain masonry building. The existing masonry structure is evaluated in its defects of primary design and construction measurements, seismic bearing capacity and durability. Based on results of evaluation, the seismic reinforcement design is introduced for improving earthquake-resistance beha...
