As one of the most common structural forms in port engineering, operation environment high-pile wharf is quite harsh and complex, its pile foundation often produces damage different degrees. Until now, there a lack efficient, safe economic detection methods. A novel precise real-time (SDD) method using both finite element modelling (FEM) 1D convolutional neural networks (CNNs) established this ...

Co-firing biomass plants are of extensive demand due to utilization of both agricultural residues (main) and natural gas (stand-by). Researchers have shown that one strategic decision in establishment of agricultural residues based plants, is location optimization problem. Moreover, mismatch between agricultural lands and biomass plants can lead to high transportation costs and related carbon d...

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...

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...

In this paper, the optimum shape of Tailor-Welded Blanks (TWB) is investigated. The optimization is performed for two different case studies. The first example is deep drawing of a TWB with dissimilar materials and uniform thicknesses and the next example is deep drawing of a TWB with similar materials and non-uniform thicknesses. The effect of blank optimization on the weld line movement is...

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...
