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...

Abstract. The work reports some numerical tests concerning the use of Embedded Truss elements implemented in Midas FEA NX software modeling a specific FRCM reinforcement system for masonry structures. efficacy finite element is demonstrated through comparison results with experimental obtained by other authors relating both to mechanical characterization materials and response arch models. appe...

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 explores flood-induced hydrodynamic and debris impact forces on masonry arch bridges using the numerical method smoothed particle hydrodynamics (SPH). Masonry make up a significant proportion of bridge stock in many parts world, including UK US. Although is durable form, those spanning watercourses can be vulnerable to effects flooding. Where fast flood flows impinge superstructure, ...

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 ...
