Book Description
"A number of researchers have conducted experimental tests on unreinforced masonry walls (URM) strengthened with advanced composite materials. Consequently, the strengthening design guidelines are limited in their scope to URM. This research aimed to investigate the behavior of reinforced masonry walls strengthened with advanced composite and subjected to out-of-plane pseudo-static cyclic load. Experimental and analytical studies were conducted to evaluate the performance of different techniques such as near surface mounted (NSM) and externally bonded (EB) fiber reinforced polymer (FRP) with epoxy resin, in addition to NSM with cementitious adhesive and fiber reinforced cementitious material (FRCM). The experimental part included three phases. In the first phase, a series of 42 reinforced masonry walls were tested to study the effectiveness of advanced composites in enhancing out-of-plane flexural capacity. The effect of long-term environmental exposure on strengthening systems was investigated in the second phase of study by testing 10 reinforced masonry walls. The third phase focused on bond behavior between the advanced composite and the concrete masonry unit at different temperatures; 56 specimens were used for this purpose. The results indicated that the non-arching strengthened reinforced masonry wall's behavior was significantly dependent on the type of fiber and fiber reinforcement ratio. The specimens strengthened with glass under combined environmental cycles exhibited an insignificant change in terms of ultimate strength as compared to laboratory conditioned specimens. The theoretical part included the investigation of bond reduction factors, seismic performance, and the nonlinear analysis of strengthened reinforced masonry wall using moment-curvature analysis. As a result of this study, the proposed model for predicting debonding strain and the moment-curvature relation presented an excellent prediction compared to the experimental results"--Abstract, page iv.

Book Description
Numerical Modeling of Masonry and Historical Structures: From Theory to Application provides detailed information on the theoretical background and practical guidelines for numerical modeling of unreinforced and reinforced (strengthened) masonry and historical structures. The book consists of four main sections, covering seismic vulnerability analysis of masonry and historical structures, numerical modeling of unreinforced masonry, numerical modeling of FRP-strengthened masonry, and numerical modeling of TRM-strengthened masonry. Each section reflects the theoretical background and current state-of-the art, providing practical guidelines for simulations and the use of input parameters. - Covers important issues relating to advanced methodologies for the seismic vulnerability assessment of masonry and historical structures - Focuses on modeling techniques used for the nonlinear analysis of unreinforced masonry and strengthened masonry structures - Follows a theory to practice approach

Book Description
The implementation of these techniques could have a significant economic impact in addition to the cultural and social impacts of conservation of the architectural heritage. Since the developed techniques are applicable to existing masonry buildings in general, it is anticipated that they will contribute to the Canadian economy through upgrading existing masonry buildings and extending their service life.

Book Description
Proceedings of a session of Structures Congress '85, held in Chicago, Illinois, September 16-18, 1985. Sponsored by the Structural Engineering Division of ASCE. This collection contains seven paper on analysis of structural masonry. Various aspects of masonry analysis are covered. Topics include: linear and nonlinear finite element modeling, as well as progressive failure of masonry subjected to in-plane loads where failure may occur only in joints or may involve both bricks and joints; a macroscopic finite element model for masonry (without individual modeling of joints and bricks or blocks) which can handle in-plane and out-of-plane loading including both transverse shear effects and nonlinearity due to cracking; cavity masonry walls subjected to out-of-plane loads; a general failure criterion for the biaxial compressive strength of masonry as well as a design method based on the ultimate strength of masonry walls; reduction in the buckling lengths and corresponding increase in the load carrying capacity of masonry walls due to restraining effects of floor slabs; wall/floor-slab interaction in brick walls that yields load eccentricities and possible capacity reductions; and a 2D-finite element model that can account for shear transfer across wythes in a composite masonry wall.

Book Description
This volume highlights the latest advances, innovations, and applications in the field of FRP composites and structures, as presented by leading international researchers and engineers at the 10th International Conference on Fibre-Reinforced Polymer (FRP) Composites in Civil Engineering (CICE), held in Istanbul, Turkey on December 8-10, 2021. It covers a diverse range of topics such as All FRP structures; Bond and interfacial stresses; Concrete-filled FRP tubular members; Concrete structures reinforced or pre-stressed with FRP; Confinement; Design issues/guidelines; Durability and long-term performance; Fire, impact and blast loading; FRP as internal reinforcement; Hybrid structures of FRP and other materials; Materials and products; Seismic retrofit of structures; Strengthening of concrete, steel, masonry and timber structures; and Testing. The contributions, which were selected by means of a rigorous international peer-review process, present a wealth of exciting ideas that will open novel research directions and foster multidisciplinary collaboration among different specialists.

Book Description
Fiber-reinforced polymers (FRP) have recently been used for retrofitting unreinforced masonry (URM) structures which are especially vulnerable to out-of-plane earthquake loads. FRPs have high strength-to-weight ratio, high stiffness-to-weight ratio, high resistance to corrosion, and ease of applicability. Experiments are conducted to test the strength and ductility of FRP-retrofitted brick walls subjected to out-of-plane loading. Based on the material properties and testing set up, nonlinear finite element models were developed to study the effects of different material parameters.
