Abstract
The main objective of the research reported in this thesis is to investigate the behaviour of reinforced masonry shear walls subjected to quasi-static loading. To achieve the aforementioned goal and better understanding of masonry shear walls behaviour, a large number of reinforced masonry shear walls is needed to experimentally tested under cyclic loading. Laboratory testing of full-scale masonry shear walls can be impractical due to space limitation, construction, and financial restriction.
Hence, the need for analytical model emerged to analyze a lot of reinforced masonry shear walls. A nonlinear program CANNY is selected to model reinforced masonry shear walls. To check the validity of the nonlinear program, it is required to compare the results of RM walls tested experimentally before with the results of the same walls modeled with the nonlinear program CANNY. The nonlinear program CANNY obtained results is found in good agreement compared with experimental results. Thus, the program is capable of simulating the response of reinforced concrete masonry shear walls under lateral loading.
The subsequent phase of model verification entailed in conducting parametric study. Parametric study was performed to investigate the different parameters that affect the behaviour of reinforced masonry shear walls. The parameters which were varied in this analysis include: Axial compressive stress, vertical reinforcement ratio (ρ_v) and the height/length (h_w/ l_w) aspect ratio. The axial compressive stress varied from zero to 2.25 MPa, vertical reinforcement ratio varied from 0.31% to 1.3%, and aspect ratio varied from 1.5 to 3.95.
The behaviour of rectangular reinforced masonry shear walls is investigated by evaluating flexure strength, lateral displacement and drift at ultimate, yield and 15% strength degradation. For each mentioned parameters displacement ductility and idealized displacement ductility at 15% strength degradation are obtained. Analytical results showed that by increasing the vertical reinforcement and axial compressive stress, ultimate and yield flexure strength increase. On the contrast, the lateral displacement and drift at maximum load, at first yield, and 15% degradation in strength decrease with this increase. Lateral displacement at maximum load had insignificant effect with vertical reinforcement ratio. Based on results the displacement ductility at 15% strength degradation and idealized displacement ductility decreased with the increase of vertical reinforcement and axial compressive stress. Although the displacement ductility at maximum load increased by increasing axial compressive stress and vertical reinforcement ratio. The aspect ratio had a great effect in all parameters and this effect appeared in all charts includes vertical reinforcement and axial compressive stress.
