The cultural, architectural, and historical heritage value of the Great Wall China drives need to maintain, rehabilitate, restore its structural integrity from artificial natural damage. In this study, a hybrid architectural visualization collapse simulation Ming (1368–1644 AD) are conducted in Blender based on unit blocks physics engine (i.e., Bullet Constraint Builder). Visualized failure pre...

When testing multi-story structures on a shaking table, most testing facilities require a reduced scale model. Producing scale test units at small scale is particularly challenging for unreinforced masonry structures. Previous work by other researchers showed that scaling of units and mortar joints is mandatory in order to obtain for the reduced scale masonry failure modes, which are similar to...

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...

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 ...

Numerical simulations are used to evaluate the damage potential of the shock-induced collapse of a pre-existing gas bubble near a rigid surface. In the context of shock wave lithotripsy, a medical procedure where focused shock waves are used to pulverize kidney stones, shock-induced bubble collapse represents a potential mechanism by which the shock energy directed at the stone may be amplified...

Abstract One of the major concerns in seismic retrofitting masonry walls is that increasing ultimate load for out-of-plane forces. In multi-story buildings, these forces may originate from hammering actions floors, when earthquake direction orthogonal to wall. A possibility counteracting displacements retaining wall by building some buttresses, is, beams lean against and disposed vertically. An...

In my article on Dr. Hezekiah Beardsley it was stated that we were unable to locate the tombstone which was removed from the green, where Dr. Beardsley and his wife were buried, to the Grove Street Cemetery. Further search has revealed his stone upon which also appears an inscription to his wife. It is to be found along the west wall of the cemetery near the beginning of the stones that were ra...
