A major industrial area and two power plants are near the epicenter of the Magnitude 8. 1 Mexico Earthquake of September 19, 1985. All investigated facilities are modern, generally well...
Seismic Rehabilitation: Why, When and How
Common methods of seismic rehabilitation are: repair of cracks, reconstruction of structural elements, addition of stiffening elements, and addition of dampers. A major consideration is...
Thoughts on a Different Approach to Seismic Design Codes
The aim of this paper is to show that some of the principles on which conventional structural design is based are not directly applicable to seismic design. Seismic design, and the corresponding...
Crossing A Freeway
The Washington State Convention and Trade Center in Seattle is being constructed on air rights spanning Interstate-5, adjacent to the seven acre Freeway Park that also spans the highway....
Transmission Structure Foundation Loads and Performance
Transmission line structures are subjected to unique loading conditions which for the majority of structures results in maximum loads which occur infrequently and act for only short periods...
Engineering Aspects of Point Versus Nonpoint Sources of Groundwater Pollution
Pollution of groundwater may occur due to a number of sources. These may be categorized into point and nonpoint sources of contamination. The purpose of this paper is to explore the issues...
Agricultural Nonpoint Source Control Program for Lake Erie
The Lake Erie Wastewater Management Study was directed at identifying and quantifying sources of P and sediment entering the lake, developing a management control strategy, and projecting...
Building Around a Building
Many, maybe most, construction disasters occur as the result of the failure of temporary structures. Despite the fact that temporary structures have a critical effect on the speed, safety...
Strengthening Old Floors
The floors of the historic City Hall and Courthouse in Minneapolis had withstood 80 years of hard use before they have to be analyzed and brought up to code. The building is about 300...
