To investigate their adequacy as energy dissipating elements during earthquakes, this paper reports on cyclic inelastic tests executed to determine the maximum strength and ductility of four concrete-filled circular steel piers joined to a foundation detail proposed to develop the full composite strength at the base of these columns. Column diameters considered were 324 and 406 mm, with D/t rat...

In difficult soil conditions, engineers sometimes choose to combine reinforced soil and spread footings instead of deep foundations. Among the available techniques for soil reinforcement, vibro stone columns are frequently used to reduce the liquefaction risk, improve the soil properties and improve the overall seismic performance. While there are different models available to evaluate the bear...

MAID is a unitary isobar model for a partial wave analysis of pion photoand electroproduction in the resonance region. It is fitted to the world data and can give predictions for multipoles, amplitudes, cross sections and polarization observables in the energy range from pion threshold up to W = 2 GeV and photon virtualities Q < 5 GeV. Using more recent experimental results from Mainz, Bates, B...

We examine the problem of optimizing classification tree evaluation for on-line and real-time applications by using GPUs. Looking at trees with continuous attributes often used in image segmentation, we first put the existing algorithms for serial and data-parallel evaluation on solid footings. We then introduce a speculative parallel algorithm designed for single instruction, multiple data (SI...

Background: The stability of structures to a great extent depends on the foundation. foundation building structure plays key role in transferring loading from soil underneath. In design, effect changes moisture content deformation and subsequent differential settlement during lifespan is often ignored. Objective: This research establishes relationship between for soils Nairobi area its environs...

The flip-flop trail is an object biography. It follows the translocal journeys of a pair of plastic sandals, unpacking the lives and landscapes hidden in the plastic. An important shoe-infrastructure enabling human mobility, flip-flops work as an offbeat proxy for globalization too. They proffer empirical footings in translocally-connected worlds in which people and the social textures and terr...

The usefulness of fiber reinforced concrete (FRC) in various civil engineering applications is indisputable. Fiber reinforced concrete has so far been successfully used in slabs on grade, shotcrete, architectural panels, precast products, offshore structures, structures in seismic regions, thin and thick repairs, crash barriers, footings, hydraulic structures and many other applications. This p...
