Behavior of Reinforced Concrete Framing Systems
On September 19, 1985, Mexico City was hit by what is believed to have been the most damaging earthquake in its recorded history. In this report, a ground motion recorded in the severely...
Summary of the Effects of the 1985 Mexico Earthquake to Power and Industrial Facilities
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...
A Clean Up in Slow Motion
Eight years have passed since contamination was first discovered at the Valley Wood Preserving plant in Turlock, Calif. Though severe chromium contamination continues to travel toward...
Safety Improvement Planning of Port and Harbour Facilities Considering Captains' Refuge Action Criteria
Since the Jane Typhoon in 1950, which induced much damages on port and harbour facilities and the ships in the ports, it has been a custom in Japan that the large-sized ships take refuge...
Navigation Problems in Upper Cook Inlet, Alaska
The Alaska District, Corps of Engineers and the Waterways Experiment Station are investigating navigation problems including tidal currents, sedimentation, and regional transportation...
Analysis of Berth Operability by Utilization of Agitation Models
Agitation models are utilized in order to predict the operability of berths for ship unloading purposes. Usually, in such models all ship displacements are measured and when one of them...
