Polyhedral Substitute Yield Conditions in Plastic Reliability Analysis
The method of invariant linear combinations of linearly associated lower bound safety margins is used for constructing upper bound approximations of the generalized reliability index with...

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...

Effects of Nonlinearities on Structural Reliability and Serviceability
Serviceability and failure limit states are computed using the Simple Plastic Theory (SPT) as well as with a Nonlinear Structural Analysis Program (NSAP). Geometric and material nonlinearities...

Endochronic Theory and Non-Llinear Stochastic Dynamics of 3-D Frames
Analytical continuous expressions of the material constitutive law are required by equivalent linearization techniques in nonlinear stochastic dynamics. Extensions to study 3D frames,...

A Tower-Like Structure with Distributed Stiffness, Mass and Plastic Zones Under Random Earthquake Loading
Random vibrations of an elastoplastic structure are treated by taking into account the finite spread of plastic zones as well as the effects of distributed mass and stiffness. Solution...

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...

Underdrain Tube Wall, Perforation Design and OBPA to Minimize Bio-Chemical Clogging
Bio-chemical clogging of underdrains has been most frequently associated with iron deposits (ochre). The underlying sticking agents have been a variety of bacteria and their exudates commonly...

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...

Researchers Seek Plastic Power

Settlement of Residual Soils
The method previously suggested by the author in 1977 for calculating settlement of non-plastic to slightly plastic Piedmont Physiographic Region residual soils is reviewed. Additional...

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...
