STARKVILLE, Miss. - Mark Horstemeyer, a Weirton native, analyzed a steel slab from the demolished Fort Steuben Bridge for the U.S. Corps of Engineers and Homeland Security at Mississippi State University.
Mark Horstemeyer was assisted by his brother, Stephen Horstemeyer, in the analysis, which found today's steel is stronger and more resistant to corrosion.
"The contents of today's steel is better in strength and its microstructure is more controlled and it contains less carbon," said mark Horstemeyer.
Tests conducted on the Fort Steuben sample included compression, tension and torsion.
Mark Horstemeyer, a mechanical engineering professor, said the federal government and highway administration has expressed concern about the many older steel bridges throughout the country.
He chairs the Center for Advanced Vehicular Studies, and Stephen Horstemeyer is the CAVS experimental laboratory manager.
There are approximately 1,000 West Virginia bridges that are structurally deficient and another 1,600 that are obsolete.
Recently, a bridge between Washington state and Canada collapsed.
Mark Horstemeyer and Stephen Horstemeyer are Weir High School graduates and the sons of Duke and Sherlene Horstemeyer of Weirton.
