A CAD-Based Construction Simulation Tool Kit for Construction Planning
Current planning and scheduling techniques place considerable reliance on the planners judgement, imagination and intuition. The result of such techniques is typically lengthy text reports...

Plastic Limit Analysis of Arch Dams
This paper applies the lower- and the Upper- bound theorems of the plasticity theory to arch dams, according to different forms of discretization for dam, two methods, namely the structural...

Low Cost Maglev Guideway Design Using Hybrid FRP-Reinforced Cocnrete

Serviceability Stress Limits for Composite Beams
Serviceability limits are increasingly becoming the critical design requirement for composite beams. A set of three illustrative design studies indicates that this is particularly true...

Ductility Effects of End Details in Composite Beams
A limit states criterion is described for quantifying the rotation capacity of members in indeterminate structures as a means of classifying ductility of structures during plastic behaviour...

The Pipe/Soil Stiffness Ratio Variable
This paper reviews the factors which affect the reactions and defines performance limitations of buried flexible plastic pipe as a function of load-induced strains and deflections. The...

Sliplining: Design and Installation Considerations for Polyethylene Pipe
The design methodology and installation procedure for polyethylene slipline renewal are discussed. When designing there are two critical phases which must be considered: (1) short-term...

Microtunneling with PVC Pipe
PVC is a suitable and economical product for sewer system construction. However, in the past, utilization of PVC sewer pipe in microtunneling was impossible due to axial thrust load limitations...

An Evaluation of Fiberglass Pipe Made by Three Different Manufacturing Processes for use in Water Transmission Projects
Fiberglass pipe is made primarily using continuous filament wound process, discontinuous helical filament wound process, and centrifugal cast process. Some 40 countries around the world...

Chemical Resistance of Thermosetting Resins Used for Cured-in-Place Pipe
This paper summarizes the chemistry, short term physical properties, and long term chemical resistance for representative epoxy vinyl ester, epoxy, and polyester resins that are currently...

European Way of Standardization in the Field of Underground Pipe Renovation
European standardization is carried out within the framework of CEN (European Committee for Standardization). The development of standards for underground pipe renovation is taking place...

Plastic Potential
Some 220,000 tons of epoxy-coated steel has been used in the construction of bridge decks since 1987, but some have raised questions about its long-term durability. New materials for prestressing...

Evaluation and Repair of Unbonded Post-Tensioned Concrete Structures
As with other forms of infrastructure, there is an ever increasing need to repair and strengthen unbonded post-tensioned concrete structures. Repairs may be necessitated for a variety...

Mechanistic Design Models of Loading and Curling in Concrete Pavements
Determination of the critical bending stress at the edge of a concrete pavement due to individual and combination effects of wheel loading and thermal curling is very crucial to any mechanistic...

North Ramp Pavement Evaluation/Rehabilitation—Houston Intercontinental Airport
The North Ramp at Houston's Intercontinental Airport is approximately 23 years old and serves Terminals A and B and also serves as a primary taxiway. Prior to having the new international...

Constitutive models
The constitutive models used in the finite element analysis of reinforced concrete structures are presented from a number of different perspectives. The first part of this chapter presents...

Dynamic Loading
This chapter deals with those problems of finite element analysis of concrete structures, which arise from the dynamic nature of loadings. Following a short enumeration of the dynamic...

Stabilization of South Texas Soils with Fly Ash
The expansive soils of south Texas have traditionally been stabilized with lime or Portland cement. As an alternative, a class F fly ash was tried to stabilize expansive soils obtained...

Treatment of Calcareous Expansive Clays
The geology, climatic condition and the environment of extreme disintegration, strong hydration and restrained leaching have a large influence on the formation of expansive clays in the...

The Use of Structural Composites in 21st Century Infrastructure Technology
The purpose of this paper is to create and transmit a sense of the unique benefits which effective application of composites technology can bring to the civil engineering. infrastructure...
