SOS For Small-Town SSOs
No matter why a small town confronts its sanitary-sewer-overflow problems, solutions are bound by the town's own resources. For two Midwestern towns, hindsight shows that...

Study of Interaction Between Pneumatic Spherical and Cylindrical Form Shells Subjected to Wind Pressure
In the design of pneumatic membrane structures, analysis of stress and deformations of structures subjected to wind is among the most important requirements. For the purpose of studying...

Snap Buckling of a Delaminated Layer in a Composite Cylinder
We investigate snap buckling of a thin delaminated layer on the inner surface of a contracting thick cylinder. Finite-deflection solutions of the layer with or without considering the...

Late Stage Damage in G30-500/PMR-15 Laminates
Damage progression has been studied experimentally under tension using [02/906]s...

Physical Model Tests of Dolos Impact Stresses
An on-going experimental study to determine impact stresses and static nesting stresses in instrumented large scale model dolosse is described in this paper. Seven dolosse were instrumented...

Monitoring of Structures During Repair of Underground Utilities
A collapse of underground utilities at a power plant required the constant monitoring of the surrounding structures during excavation and replacement of the damaged pipes. A computer-based...

High-Strain Kinetic Testing of Deep Foundations
High-strain kinetic testing involves the upward decelerating or accelerating of a mass and using its inertial force to axial prolonged pulse at the head of a pile. Currently available...

Low Strain Dynamic Testing of Wood Piles Supporting an Existing Pier
This paper presents a case history where low strain dynamic testing was performed to test wood piles supporting an existing structure. Under consideration is a 183 m long wooden pier constructed...

Long-Term Monitoring of Civil Structures using Smart Structures Techniques
A smart monitoring program for a hybrid concrete-steel building in Washington, D.C. has been developed. The building is currently being instrumented with a variety of strain and corrosion...

Steady-State Analysis of Buckle Propagation
A novel finite element technique for the analysis of buckle propagation in pipelines is presented. The propagation pressure, propagation profile, the state of stress, and deformation during...

A Shape-Finding Finite Element Analysis for an Equally-Stressed Surface in Membrane Structures
A finite element method is proposed to obtain an equally-stressed surface in a membrane structure, where the displacements and rotations of a membrane are in general finite and nonlinear....

Elasto - Plastic Analysis of Cable Net Structures
This paper presents a Newton-Raphson interaction technique which takes account of plastic cable strains while iterating on the nodal equilibrium equations of cable net structures. The...

Nonlinear Behavior of Northlight Reinforced Concrete Shells
The behavior of northlight shells is very sensitive to the boundary conditions at the top and bottom edges of the shell. The aim of this paper is to investigate the structural action of...

Rotating Crack Model and Fracture in a R/C Medium
In this study the potential of the development of cracks in the members of a reinforced concrete large panel structure is considered. The analysis is carried out using finite element modeling...

Load - Settlement Predictions for Spread Footing Event

Prediction of Settlement for Five Footings

Predictions of Footing Tests Sponsored by the FHWA Using a Strain Hardening Elastoplastic Constitutive Model

Compressibility of Clays: Fundamental and Practical Aspects
The compressibility of natural clays is influenced by strain rate, temperature, sampling disturbance, stress path and some restructuration factors. The first part of the paper reviews...

Towards a Rational Method of Predicting Settlements of Spread Footings on Sand
Prediction of settlements of both large and small spread footings on sand has traditionally been carried out using methods which are largely empirical. In recent years, advances have been...

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...
