A Prescriptive Criterion for Amphibious Foundation Design
… development. Information on the structural design of such buildings is limited and most of the current knowledge regarding amphibious structures is presented in architectural applications. The primary objective of this research is to develop a prescriptive approach to the structural design …

Foundation Design of Low Volume Roads: Evaluation and Performance
… of LVRs to their ADT, layer thicknesses, foundation material properties, and maintenance. A secondary objective was to evaluate if the Dynamic Cone Penetrometer (DCP) is an acceptable tool in determining the subgrade support by using it to measure the penetration resistances of the …

Advanced Interaction Analysis for Foundation Design and Coastal Cliff Stability
… fluid-cliff interaction (FCI) and fluid–cliff–foundation interaction (FCFI) and identifying the critical zones in failure and critical construction distance from the cliff crest, beyond which the impact of wave action on foundation performance becomes negligible. Methodology A comprehensive …

A perioperative medicine clinical decision support system: foundation, design, development, evaluation, and the standards
… opinions. These heuristics will serve as the foundation for a subsequent CDS tool in perioperative medicine. Methods: In this descriptive study, we manually extracted key demographic and medication-related data from the records of 100 randomly-selected patients at the Minneapolis VA's …

Reliability Analysis of the HEC-18 Scour Equation and AASHTO Deep Foundation Design Codes
… project studied the reliability of driven pile foundations subjected to scour, gravity loads including dead loads and live loads, and their combinations. The design of the foundation followed the procedures of the AASHTO LRFD Bridge Design Specification. The design methods were the HEC-18 pier …

An evaluation of the utility of four in-situ test methods for transmission line foundation design
… Each structure is, in turn, supported by a foundation or foundations. The prevailing philosophy behind transmission structure design to date has been based on the notion that information for geotechnical conditions is sparse and relatively simple in nature. Within this context, it is useful …

Análise de fundações de máquinas sujeitas a excitações verticais
… results of dynamic analyses used for machine foundation design. The tests were carried out on blocks submitted to vertical harmonic excitation with amplitude as function of frequence. In the analyses the soil was considered either as an elastic half space or as a set of linear springs. In …

Métodos de cálculo de atrito negativo em estacas - estudo e discussão
… and how to deal with this problem in deep foundation design are discussed. Two field problems were analyzed according to the above cited methods.

Residential building design : comprehensive comparative guidelines for building single-family dwellings in Hawaii
… environmental factors that challenge the home designers of Hawaii. The depletion of renewable natural resources and global warming trends foreshadow energy shortage and the increases of hurricane frequency. Thus, it is essential that future homes in Hawaii be energy efficient, earthquake …

Design of lightweight prefabricated home foundation manufactured via industrial large scale polymer additive manufacturing
… light-weight, low cost alternative to concrete foundations for dwelling home construction. Worldwide, UN HABITAT estimates suggest nearly 1.6 billion people lack access to adequate shelter including 150 million homeless individuals. Home affordability is limited by expensive materials that …

Aurora: Lunar Surface Power Plant
… mission will require a deep understanding of the foundational requirements that will guide the design and planning sequence of the lunar power system. This research is focused on the infrastructure design of a lunar surface power plant, addressing the structural and civil systems required to …

Acceptance of silent piling technology among local authorities in Malaysia
In Malaysia, the foundation design and piling method generally relies on the conventional method. However, the construction work sometimes contributed to some bad effects such as noise and vibration disturbance. Silent piling technology is the new piling method used in construction activities in …

Performance of U/P finite elements subjected to nearly incompressible linear axisymmetric orthotropic conditions
… in such cases, other elements should be used. In foundation design, it is important to accurately model soil deformations and stresses. If the ground conditions are proven to be best modeled orthotropic instead of isotropic, then a finite element analysis should be implemented. If the soil is also …

A Finite Difference Approach to Modeling High Velocity/Variable Loads using the Timoshenko Beam Model
… electromagnetic loading, and other non-linear or design specific effects contribute to areas of high stresses/strains over the length of the rail/beam during launch. This paper outlines the use of the Timoshenko beam model, a model which builds upon the traditional Bernoulli-Euler beam theory with …

Collapse of stone column foundations due to inundation.
An important problem encountered by foundation engineers involves partially saturated soils which possess considerable in-situ dry strength that is largely lost when the soils become wetted. Foundation design in such soils is difficult at best. In many cases, deep foundations may be required to …

Three-dimensional modelling of heat transfer from slab floors
… savings in both conventional and earth-sheltered designs. Because of the complexity of the building/soil/atmosphere interaction, however, important aspects of earth-coupled heat transfer are not well understood. There is a particular lack of three-dimensional foundation heat loss data. In this …

Structural fatigue assessment and optimisation of offshore wind turbine jacket foundations.
… lower the capital and operational costs. Jacket foundations are increasingly used in offshore wind due to their relatively light weight and adaptability in deep waters. However, the contemporary jacket designs are based on conservative practices from the oil and gas industry. There is still …

Dynamic Full-Scale Testing of a Pile Cap with Loose Silty Sand Backfill
Pile caps are used in foundation design to aid multiple single piles to act as a pile group to resist lateral forces that may cause overturning moments. The pile cap and pile group resist these forces by pile-soil-pile interaction, base and side friction along the pile cap-backfill interface, and …

Interaction of earthquake fault rupture with shallow foundations
… surface infrastructure, esepcially for shallow foundations, and suggested that appropriate foundation design could protect buildings from significant damage.<br/><br/>The focus of this research is to imrpove understanding of the effects of earthquake fault propagation through soil and its …
