This research work aims to present an experimental study concerning the effect of openings in out-of-plane (OOP) behaviour masonry infills RC buildings. The campaign comprises OOP testing three full-scale infill walls made up horizontal hollow clay bricks, two them with a central window and remaining one door. One specimens opening was first subjected previous in-plane test and, after that, dam...

Laboratory experimental data is often erroneous. This error is more apparent in data obtained from testing of anisotropic composite materials such as masonry wall panels. In this paper data colleted from the laboratory tests of masonry panels is presented. Methodologies for reducing (correcting) error in laboratory tested data are discussed. The concept of stiffness/strength corrector to model ...

On April 25, 2015, a M7.8 earthquake rattled central Nepal; ground motion recorded in Kantipath, Kathmandu, 76.86 km east of the epicenter suggested that the low-frequency component was dominant. We consider data from eight aftershocks following the Gorkha earthquake and analyze ground motion characteristics; we found that most of the ground motion records are dominated by low frequencies for e...

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...

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 ...

The influence of infills on the seismic response frame structures has been long recognised. On one hand, presence may be beneficial, due to their contribution dissipate energy. other irregular infill distributions in plan or elevation can lead concentration displacement demand localised parts building. It is noted that lack more panels depend original building layout generated by collapse durin...
