Response of the San Juan Bautista 156/101 Bridge to the 1979 Coyote Lake Earthquake
Strong-motion accelerograms are used to examine the response of a multiple-span highway bridge to earthquake loading. Estimates of modal frequencies and damping values for the first two...
Dynamic Response of Highway Guardrail Post Foundations
The highway departments use two types of guardrail posts: a circular wood post and a steel W6 multiplied by 8. 5 post. The current specifications require the steel post to be placed in...
Reshaping Providence

Highway Quality Level Program
This article describes three versions of BASIC programs for microcomputers, prepared for the Federal Highway Administration, to calculate a statistical measure of highway quality. Using...
Parking Lot Gets White Top
The many-acre parking lot at the Valley Fair Mall shopping center in Salt Lake City, Utah is described. In 1985 the asphalt pavement was overlaid with concrete, making it one of the relatively...
Interstate Agreements for Water Transfers
Any state is typically subjected to opposing forces that wish to 1) preserve limited water resources for future in-state uses, or 2) to export that resource for out-of-state use. Statutes...
Tunneling Around Ft. McHenry
The world's largest underwater tunnel was built out of sight and sound of Ft. McHenry. The 4,000 ft tunnel needed to take I-95 from shore to shore had to be extended to 7,200...
Highway Infrastructure
Opportunities for Innovation
Our national commitment to financing the rebuilding of America's highway intrastructure represents a very expensive, long term investment. The challenge facing highway engineers...
Equipment Requirements for Concrete Recycling
Concrete recycling projects have been completed in a number of states. As the transportation infrastructure ages, concrete recycling will become a common construction operation. Concrete...
Infrastructure in a Hurry
The City of Austin, Texas has experienced tremendous growth since the early 1970s. Until recently, however, infrastructure development lagged. Now the city is engaged in a $1 billion infrastructure...
Optimization for Overall Stability
This paper synthesizes design of trusses for linear stability constraint as an optimization problem where linear stability is defined as a generalized eigenvalue problem and presents a...
