Upper-Bound Estimate of the Reliability of Plastic Slabs
This paper gives a brief presentation of some recent results on probabilistic analysis of plastic slabs, especially reinforced concrete slabs. The estimate of the reliability of such slabs...
An Investigation of Field Performance of Reinforced Plastic Mortar Pipes
Every year many new pipe materials appear on the market for various applications. One of the important factors the design engineer and the user should consider while evaluating new products...
Pipeline Rehabilitation with Polyolefin Pipe
This paper provides an introductory discussion on the rehabilitation of a deteriorated pipe structure by insertion renewal with continuous lengths of polyolefin pipe. This sliplining or...
Ultrasonic Flow Meter Testing
Six ultrasonic flow meters were tested in a hydraulics laboratory. Accuracies better than 2% were obtained with two transit-time meters on 14 inch diameter steel tubing. Poorer accuracies...
Drag Characteristics of Spheres in Bingham Fluids
R.W. Ansley and T.N. Smith's type of drag relation can be traced back closely, if not completely, to the Newtonian drag curve. The equivalent diameter for a sphere in a Bingham...
Analysis of Plastic Soil in Contact with Cavitose Bedrock
A numerical analysis has been conducted to evaluate the stress deformational response of highly plastic soils in contact with cavitose Bedrock. The numerical idealization represents the...
Plastic Concrete Cutoff Walls
The studies revealed that plastic concrete can be prepared having a coefficient of hydraulic conductivity that is less than 1 multiplied by 10** minus **7 cm/sec. The shear strength of...
Hydraulic Design Limitations for Gravity Flexible (Non-Rigid) Plastic Pipes Flowing with a Free Water Surface
Hydraulic design limitations are necessary for gravity plastic pipes when designed for use as a sanitary sewer, flowing part full with a free water surface. The limitation for pipes designed...
Practical Analysis of Flexibly-Connected Building Frames
Modeling of flexible connection behavior as elastic-perfectly plastic is proposed for analysis of building frames, and results based on this idealization are compared with fully non-linear...
Reliability of Structural Systems With Multiple Limit States
The purpose of this paper is to present a systematic treatment of the reliability of structural systems with multiple limit states. Several performance criteria (e. g. , excessive deflection,...
Sewer-Septic Tank Hybrid Promises Savings
Until recently the only options for sewage were the septic tank/leach field or conventional sewers. In some cases a hybrid of the two, called the septic tank/effluent drain, is less costly...
Moisture Effects on Extruded Polystyrene Insulation
The amount of moisture within the insulation was determined by carefully weighing each sample and then measuring its volume. Two methods of measuring thermal conductivity were used. The...
Pavement Design for a Break Bulk Terminal Yard
This paper discusses the practical application of mechanistic pavement design principles for a proposed 8. 1 ha break bulk cargo storage yard that is part of the Port of Portland's...
Sulfide Corrosion and Control in the City of Modesto Primary Effluent Outfall (
The City of Modesto has a 60 inch diameter, 6- one-half mile long reinforced concrete pipeline conveying primary effluent from the primary treatment plant to the remote oxidation pond...
Optimization for Overall Stability
This paper synthesizes design of trusses for linear stability constraint as an optimization problem where linear stability is defined as a generalized eigenvalue problem and presents a...
On the Design of Continuous Composite Beams
Methods of analysis and design of continuous composite beams are presented. Numerical analysis is used to determine the effective width of the slabs to be used in design. The influence...
Behavior and Strength of Stub-Girder Floor Systems
The paper presents a detailed evaluation of the behavior and strength characteristics of the stub-girder floor system. This is a composite girder and beam structure that integrates the...
Reshaping the Future of Plastic Buildings
Plastic structures have been around for 40 years, but have for the most part been showcases with little use in the mainstream of the building industry. To be used effectively, plastics...
Modular Plastic Media for Shallow Bed Trickling Filter Applications
Little specific data is available for less sophisticated trickling filter systems which employ recent plastic media designs for shallow bed filters without the added cost of subsequent...
Metal and Plastic Pipelines: Design and Construction Aspects
This paper discusses design and construction aspects of four cross-country pipelines that were built in central Alberta, Canada during 1982-1983. The first two pipelines, carrying different...
