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...

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...

Intelligent Decision Support System for Stage Discharge Analysis
A Decision Support System (DSS) for fitting stage-discharge (S-D) relations is being developed by the University of Manitoba, Facility for Intelligent Decision Support, for Environment...

Borehole Fluid Dynamic Temperature Logging to Evaluate Fracture Hydraulic Properties

Flow Capacity of Rehabilitated Sanitary Sewers

Bridge Rating Using Influence Surface for Curved Bridge Structures
A fairly sizeable number of curved steel bridges in Louisiana need to be rated and influence lines required to be stored. A methodology is developed and rating procedures are established....

Pavement Treatment in Ohio Transportation System
This paper presents a modification of the original method in which the concept of fuzzy set theory is applied in the calculation of the PCR. Fuzzy numbers are introduced to represent those...

Bridge Condition Rating Using Fuzzy Sets and an Eigenvector of Priority Settings
A simplified methodology for combining the condition rating of the various elements of bridge components (deck, superstructure or substructure) is developed using a multi-attributive decision...

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...

Finite Strain Consolidation for Vertical Drains
Consolidation equations for vertical prefabricated drains which consider finite vertical strain of the soil are derived. Estimated consolidation times are shorter when finite soil strain...

A Procedure for Predicting Seismic Deformation of Earth Structures
This paper presents an analysis procedure for predicting the earthquake induced displacements of earth structures. The procedure is an extension of the simple Newmark method from a single-degree-of-freedom...
