One of the parameters that has been identified as influencing the structural response of buildings is the dynamic Modulus of Elasticity of masonry units. The first aim of this paper is to experimentally investigate the use of high frequency sinusoidal loading to determine the dynamic Modulus of Elasticity of masonry units. The Longitudinal Vibration and the Ultrasonic Pulse methods were origina...

Basically, all masonry units are suitable for tests. Randomly sample 5 masonry units for determining the moisture content. Additionally, for tests with no preload, randomly sample a further 15 masonry units for the construction of the specimens and, for tests with preload, randomly sample a further 15 masonry units per preload value for the construction of the specimens. A minimum of 3 preload ...

Water content affects mortar and masonry properties however, it is often determined by the mason assessing mortar workability. This can lead to lack of consistency and variable masonry performance. This paper investigates the compressive, flexural and bond strength and stiffness of brick masonry bound with natural hydraulic limes (NHL2, 3.5 and 5), hydrated lime (calcium limeCL90s) and cement-l...

Strengthening of un-reinforced masonry (URM) structures to improve its seismic performance is not only well recognized among the research community but also getting attention of practicing engineers around the globe. The estimation of lateral capacity and performance of masonry becomes complex because of heterogeneous nature of its constituent materials and other associated problems. Heterogene...

4 FRP strengthening systems for infill masonry walls are typically designed to resist flexural stresses due to out-of5 plane pressure. Previous research has shown that there are potential premature failure mechanisms due to shear 6 sliding of the infill, which could reduce the effectiveness of the strengthening system. Current design guidelines for 7 strengthening of masonry walls with fiber-re...

Performance based design (PBD) is an iterative exercise in which a preliminary trial design of the building structure is selected and if the selected trial design of the building structure does not conform to the desired performance objective, the trial design is revised. In this context, development of a fundamental approach for performance based seismic design of masonry infilled frames with ...

The evolution of the damage mechanic properties for un-reinforced masonry panels under dynamic loads is critical in a time-domain analysis of masonry shear walls. This research project experimentally investigates the evolution of the properties of the damage variable for unreinforced masonry panels, subject to dynamic in-plane displacement controlled strain. This paper presents the theoretical ...

At present, many of the historic masonry structures in the most important seismic zone of Argentina present damages due to the actions to which they have been subjected. Therefore, it is necessary to study the behavior of walls of ceramic masonry of great thickness. This work presents the comparison between the results obtained from the numerical simulation of ceramic masonry walls subjected to...

Masonry is one of the world’s most durable construction materials. Masonry structures can remain in service for hundreds or even thousands of years. Masonry structures often outlive their designers, their original design documents, and their original functions. When historic masonry structures are evaluated for preservation, adaptive use, or additions, there are numerous questions that may aris...

The application of steel fiber reinforced polymer (SRP) as a means of increasing the capacity of masonry columns is investigated in this study. The behavior of 23 solid-brick specimens that are externally wrapped by SRP sheets in low volumetric ratios is presented. The specimens are subjected to axial monotonic load until failure occurs. Two widely used types of masonry columns of differing squ...
