Galveston Bay 3-D Model Study Channel Deepening Circulation and Salinity Results
The effects of deepening the Houston Ship Channel through the Galveston Bay estuary are predicted using the 3-D finite element numerical model RMA10-WES. The primary concern is the effect...
Composite Space Frame?Experimental/Analytical Study
This paper describes work carried out on a composite space frame system. The system, previously developed for roof construction, comprised a pyramidal arrangement of steel angles and circular...
A New Method from China to Determine Load-Carrying Capacity for CFST Members
The most common research method for CFST (concrete-filled steel tubular) members is to study the behaviors of the steel tube and the core concrete separately, then add them together to...
Replacement Steel Bridges for Motorway Widening
Case studies are presented of new applications of composite construction which offer speedy construction of replacement bridges over existing motorways. Spans of 45 m clear the widened...
Trenchless Diversity Fuels Growth of Construction Activities
This paper describes a variety of trenchless technology methods of reconstructing America's decaying pipeline infrastructure by using minimum and /or 'no-dig processes'. The decay of our...
Pipeline Leak Detection Based on Mass Balance
Current technologies in Supervisory Control and Data Acquisition (SCADA) systems enable pipeline leak detection to be carried out in real time by software-based methods. This paper discusses...
Real World Applications of Pipeline Leak Detection
This paper covers various leak detection methodologies and how they are integrated into the Williams Pipe Line system. Special emphasis is given to the dynamic model method of leak detection...
Installing a Raw Water Line by Microtunneling
Construction began in 1991 on a new water treatment plan for the Towns of Cary and Apex, with B. Everett Jordan Lake as a water source. Installation of two 1,400 mm raw water lines approximately...
The Ivie Pipeline Delivering Water to West Texas
The Ivie Pipeline is a $76,000,000 - 156-mile long water pipeline being constructed in West Texas. This paper describes highlights of the planning, design, and construction phase....
Selection and use of Pipeline Leak Detection Methods for Liability Management into the 21st Century
Pipeline leak detection systems have been in use for many years on all types of pipelines with various products being transported. Pipeline owners and operators are subject to stringent...
Preventing Coating Delamination in Prestressed Concrete Pipe
This paper describes the results of experimental and analytical studies of mortar coating delamination of prestressed of concrete cylinder pipe. Coating delamination resulting from radial...
Innovative Contracting Practices in Developing an Advanced Freeway Management System
Throughout the nation, many public agencies have determined to incorporate time saving and cost effective project innovations while maintaining and upgrading project quality. One possible...
Condition Data Reduction for Pavement Management
A methodology is proposed for the identification of uniformly behaving deterioration regions of infrastructure facilities. Such `homogeneous' regions constitute the basic units that should...
Nondestructive Testing Role in Repair and Rehabilitation of Concrete Structures
Nondestructive testing (NDT) methods are increasingly being used to assess the condition of structural concrete. The paper discusses applications of NDT methods for forensic investigation...
Application of Digital Images and Processing for As-Built Construction Drawings
The production of as-built drawings is a labor intensive activity that often provides the facility owner with inaccurate or incomplete final drawings. This paper briefly reviews work accomplished...
Finite Element Analysis of Slabs-on-Grade Using Higher Order Subgrade Soil Models
Incorporation of the two-parameter, Kerr and Zhemochkin-Sinitsyn-Shtaerman subgrade models into finite element code ILLI-SLAB is described. The two conventional idealizations, namely the...
Unified Constitutive Model for Airport Pavements
A unified constitutive model that allows for significant behavioral characteristics of materials and interfaces in airport pavement is implemented in a nonlinear finite element procedure....
Portland Cement Concrete Apron Pavement Design Study for King Fahd International Airport in Saudi Arabia
