Sprayed-On Polymer Mortar Construction
Sprayed-on polymer mortar has been used to construct low-cost, lightweight structures in a variety of locations. The addition of the two-component additive to one cubic yard of mortar...

Predicted Fatigue Life Behavior of Stay Cables
Monte Carlo simulation results are used to illustrate the relationship between the fatigue lives of short prestressing strand test specimens and long strand stay cables. Long stay cables...

Effect of High Frequency Response on Fatigue of Offshore Structures
Welded steel specimens have been tested under several loading spectra to determine the effect on fatigue life of high frequency components in the psd of the stress or strain in the joint....

Early Age Strength Detection for In-situ Concrete
In recent years it has become increasingly beneficial to know the quality of concrete as soon as possible after it has been placed. This is especially true for high-rise concrete buildings...

Development of Analytical Models for Reinforced Concrete
A computer program called WCOMR was developed to analyze the characteristics of RC walls subjected to reversed cyclic loading. The WCOMR comprises RC element idealization described by...

Wind Tunnel Testing of the Karnali River Bridge
An extended wind tunnel testing program of the erection procedures and the stability of the completed one-tower cable-stayed Karnali River Bridge was conducted with the help of full bridge...

Wood Diaphragms: Performance Requirements and Analytical Modeling
Wood diaphragms represent the principal mechanisms for resisting lateral loads in many light-frame buildings. While recent research has provided several mathematical models for predicting...

Looking at the Past
The story of bridge building is related through a look at the bridges of the past, from earliest bridges of record to the latest cable-stayed successes. Progress in bridge development...

Weathering Steel Bridges ? State of the Art
State of the art dissertations on materials that have been in commercial use for over a century are not likely to illustrate major new and innovative breakthroughs. Instead, the state...
