Recent seismic events such as the Northridge earthquake have left behind, along with destruction serious doubts about the performance of the welded moment connection, until now the most popular and reliable steel beam-column ...

The effects of coarse aggregate properties and characteristics on the properties of hardened concrete were examined in this experimental program. Tests were performed to determine effects on modulus of elasticity, compressive ...

The use of abrasive blasting to remove paint containing lead, cadmium, and chromium from steel bridges is producing contaminated spent blasting media which may be classified as hazardous by the Environmental Protection ...

This thesis addresses the impact of aggregate gradation and type on Hot Mix Asphaltic Concrete (HMAC) characteristics. Several different, but related topics are covered and results from several experiments are presented. ...

Measurements of turbulence characteristics were performed in a laboratory meandering river channel. The measurements were performed using a single hot-film anemometer at five sections beginning from the apex of the first ...

Research was conducted to apply the Spectral-Analysis-of-Surface-Waves (SASW) method to the identification of internal cracking in concrete structural elements such as beams and columns. The SASW method is a nondestructive ...

In a meandering river, both the bends and the transverse bed slopes influence the turbulence in the flow. As part of a research project to study the turbulence characteristics in a meandering laboratory river channel, ...
