Determining Optimal Parameter Dimensions for Water Distribution Network Models
Water distribution systems contain a large number of pipes whose roughness factors are unknown prior to model calibration. During the calibration process, pipe roughnesses for each link...

Concrete Watertight Structures and Hazardous Liquid Containment
The purpose of Concrete Watertight Structures and Hazardous Liquid Containment is to provide a practical guide for practicing engineers who...

Roller Compacted Concrete IV
This engineering manual Roller-Compacted Concrete from the U.S. Army Corps of Engineers provides information and guidance on the use of roller-compacted...

Solar Stretch
Extrapolating from structural work with textile or metal membrane roofs to cover silos, assembly halls and sports stadia, Schlaich, Bergermann and Partners, a structural engineering firm...

Estimating Clay Liner and Cover Permeability Using Computational Neural Networks
The ability to provide a quick estimate of the permeability value to be expected in laboratory testing (of field samples) would help to predict potential problems in meeting the permeability...

Design of Clay Liner Permeability at Laboratory Scale Using Expert Systems
Unlike other soil properties, permeability of compacted clay is highly variable. The large number of parameters that affect permeability of compacted clay renders permeability unpredictable...

Computer Modelling of Comminuting Granular Media
Using generalized continuum mechanics, generalized damage theories for granular materials in comminution processes are proposed. The generalization is accomplished by treating the average...

Hybrid Finite Element/Discrete Element Model for Large Deformation Geotechnical Engineering Problems
New hybrid finite element/discrete element computational code was developed for large deformation geotechnical engineering problems with granular materials. The code uses the finite element...

Alternative Decisions for Space-Based Scheduling in Multi-Story Projects
SCaRC (Space-Based and Resource-Based) is a prototype knowledge-based scheduling system that acknowledges work space as a scheduling constraint. The SCaRC system comprises different scheduling...

MoveCapPlan: In Integrated System for Planning and Controlling Construction Material Laydown and Handling
This paper focuses on modeling and improving flow. It presents a computer-based system for planning and controlling construction material laydown and handling. This system, named MoveCapPlan;...

Estimating Sediment Relative Density Using an Impact Core Sampler and Wave Equation-based Pile Analysis
This paper presents a case history in which soil sample drive resistance was modeled with a wave equation-based pile analysis computer program to estimate in situ sediment relative densities...

Computer Implementation of Fuzzy Reasoning in Tendering
There are a lot of risk factors need to be considered in tendering in the construction industry. Examples are a) The market conditions: the degree of competition, the prevailing and the...

Numerical Modeling of Initial Ground Movement in an Instrumented Superconducting Super Collider Shaft
A 5.5 m diameter shaft was sunk into a rock formation of Taylor Marl to a depth of 61 m at the Superconducting Super collider (SSC) site. Numerical modeling using finite difference analysis...

Mat Foundation Design: An Historical Perspective
Nearly a half century ago, Karl Terzaghi rationalized the analysis and design of mat foundations with the conclusion that subgrade reaction was the most important variable. Soon after...

WAK and Full-Scale Load Tests on Granular Fill
For footings on granular fill that includes cobble- and boulder-size materials, in situ tests cannot be used to estimate foundation settlement because such fill is difficult to explore...

An Alternative Formulation of Volume-change Behavior of Soils
The traditional approach based on the semi-logarithmic representation of volume change data is known to work relatively well for prediction of ground settlements. This approach has been...

Settlement of Large Mat on Deep Compressible Soil
This case history describes the settlement analyses for a large load compensated (floating) mat foundation on a deep deposit of normally consolidated clay of variable thickness. Large...

Influence of Flexible Mat on Settlements of Marine Clay
Highly compressible marine clays occur extensively in coastal regions. In lieu of traditional pile or raft foundations in such weak soils, recently a flexible mat system has been developed...

Measured Downdrag on Seven Coated and Uncoated Piles in New Orleans
A site outside of New Orleans, Louisiana was selected as part of a research effort to study the phenomenon of downdrag on bitumen-coated piles. Two steel pipe piles, two timber piles,...

Settlement and Deformation Response of a Bridge Footing on a Sloped Fill
The problem of settlement of spread footings located within or near granular slopes has been investigated in the laboratory using a large testing facility. Based on these results, footings...
