It is very difficult to predict the load carrying capacity of bored piles because of the Complications that may arise such as difficult ground conditions , presence of ground water, method of boring, method of concreting, quality of concrete, expertise of the construction staff, the ground conditions and the pile geometry. Therefore the Pile design must be accompanied by in situ load testing. M...

Six buildings were overturned in the town of Onagawa during the 2011 Great East Japan tsunami. This study investigates the possible failure mechanisms of building overturning during tsunami flow. The tsunami inundation depth and flow velocity at each overturned building were recalculated by using a tsunami numerical simulation and verified using a recorded video. The overturning moment is a res...

This paper examines the effects of monotonic and cyclic temperature changes a model energy pile (diameter=25 mm, length=264 mm) on variations in volumetric water content surrounding unsaturated sand. Water flowed away from during heating to 36°C toward cooling 5°C, causing soil drying wetting near pile, respectively. The change was time-dependent, nonlinear, slower than continued evolve after s...

Many offshore structures are subjected to overturning moments due to wind load, wave pressure, and ship impacts. Also most of retaining walls are subjected to horizontal forces and bending moments, these forces are due to earth pressure. For foundations in such structures, usually a combination of vertical and batter piles is used. Little information is available in the literature about estimat...

In Australia, microhylid frogs are found almost exclusively in the tropical north-east, but in this region diversity is high. Sixteen species occur in the Wet Tropics region and a further six species are found further north on Cape York Peninsula. Most Australian microhylid species belong to the genus Cophixalus (18 species). The majority of these have highly localized distributions, with two-t...

Application of pile-raft foundations, which are known as “compound foundations”, is a suitable alternative in the case of heavy load structures. The interaction behavior of pile raft foundations makes these systems very complex to analyze. Different methods have been proposed to determine the bearing capacity of piled raft systems and distribution of loads between the components, i.e. pile grou...

Remediation of slope failures requires stabilization alternatives that address causes of slope instability. Slope reinforcement and pile stabilization systems, if properly designed, are effective in preventing slope movements in weak soils. Soil load transfer to pile elements from the lateral soil movement as occurs in slope failures is a complex soil-structure interaction problem, and the sign...

Approved for public release; distribution is unlimited. 1. Purpose. This manual provides information, foundation exploration and testing procedures, load test methods, analysis techniques, allowable criteria , design procedures, and construction consideration for the selection, design, and installation of pile foundations. The guidance is based on the present state of the technology for pile-so...

A semi-quantitative real-time RT-PCR assay was designed to measure gonococcal pilin antigenic variation (SQ-PCR Av assay). This assay employs 17 hybridization probe sets that quantitate subpopulations of pilin transcripts carrying different silent pilin copy sequences and one set that detects total pilE transcript levels. Mixtures of a DNA standard carrying the silent copy being detected and a ...

Received: June 12, 2017 Revised: October 24, 2017 Accepted: November 03, 2017 Abstract: Background and Objective: Prestressed high strength concrete pipe pile (PHC) shows brittle fracture when subjected to more than its own bearing capacity. Therefore, the non-prestressed steel bar is added to the PHC pipe pile, that is, the mixed reinforced pipe pile (PRC). The mechanical behavior of PRC group...
