One of the parameters identified as influencing the structural response of buildings is the dynamic Modulus of Elasticity of masonry. The Longitudinal Vibration Test Method and the Ultrasonic Pulse Methods were developed for the dynamic testing of concrete specimens. These two dynamic procedures are to be tested on masonry prisms to provide a verification of the methods. The first aim of this p...

This paper presents an experimental program dealing with the shear strengthening with FRP systems of URM walls built with concrete and clay units. Ten concrete and five clay masonry panels, strengthened with FRP composites in the form of laminates and rods, and stainless steel, were loaded along the wall diagonal to observe their shear performance. The dimension of the concrete masonry panels w...

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...

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...

This paper reports the progress in research and development of a mobile bricklaying robot for use on the construction site. Its practical and market orientated design has been a key aspect of the project from the start.

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...
