A method of analysis of arbitrarily shaped prestressed concrete
members for biaxial bending is given. The stress-strain curve of
the concrete is represented by two parabolic segments, and the
effects of strain hardening of the steel are included in the analysis.
An iterative numerical procedure is used to solve for...
This paper presents an application of the wave equation to the
problem of selecting a driving hammer for prestressed concrete piles.
The potentially damaging effects of these types of hammers on various
prestressed concrete piles were analyzed by means of parametric
studies carried out on a hypothetical group of problems...
Design methods for pavement mixtures containing recycled asphalt
concrete have been explored in many studies. Most methods of design
are modelled after procedures originally developed for conventional
construction with virgin raw materials. The unique properties of aged
asphalt as raw material are rarely considered when applying conventional
procedures. The approach...
Earthquake engineering analyses are often performed using shallow, crustal earthquake motions (e.g., 1940 El Centro). However, large areas of the world are subject to subduction zone earthquake motions (e.g., the Pacific Northwest). A subduction zone earthquake motion is characterized by its long duration (e.g., strong shaking lasts for more than...
This thesis presents a procedure to identify and evaluate forest
arterial and collector networks. The procedure identifies those
decision criteria important in evaluating both the arterial and
collector networks and the specific facilities identified on these
networks. The procedure incorporates the decision criteria and results
from network and facility analysis...
Testing of asphalt binders and asphalt-aggregate mixtures using dynamic
mechanical analysis is becoming popular with improvements in high-speed
computers, precision equipment, and computer software. Researchers are trying
to describe the behavior of asphalt binders and asphalt-aggregate mixtures in
terms of their time- and temperature-dependent linear viscoelastic behavior.
The objectives of...
The implementation and construction of Mechanically Stabilized Earth (MSE) walls has undergone substantial expansions in recent years, owing to its relatively low cost, ease of construction, and high efficiency compared to conventional retaining methods. As a result, MSE walls are being constructed to greater heights with complex features (e.g. multiple...
To facilitate the evaluation and design of structures subjected to fluid loading, a study of fluid-structure interaction (FSI) using the particle finite element method (PFEM) is presented to approximate the responses and sensitivities of structures which interact with fluid. A wide range of structural types are permissible by making no...
