Fran-Spotting
When Hurricane Fran slammed into the North Carolina coast last September, it ravaged a fragile barrier island system already torn up by Hurricane Bertha two months before. The result was...
A Dual Answer to Seismic Stress (Available only in the Structural Engineering Special Issue)
Are two systems better than one? When it comes to high-rise seismic design post-Northridge, the answer may be yes, based on studies conducted by CBM Engineers, Inc., Houston. The aftermath...
A Turnaround for Hangar Design
As the military's airplanes get larger and budgets get tighter, building hangars becomes more of a challenge. But by giving conventional rectangular hangar shapes a 90 degree...

Putting the Wraps on Quakes
With bridges deteriorating all over the country at an alarming rate, state DOTs are searching for cost-effective retrofit solutions that will protect our aging bridge inventory from seismic...
Tracking Seismic Hazards
Union Station in downtown Portland, Ore. is a historic landmark but also a seismic risk. Engineers were charged with making a priority list of hazards so that the owners could prioritize...
Guidelines for Seismic Evaluation and Design of Petrochemical Facilities
These guidelines are intended to provide practical recommendations on several areas which affect the safety of a petrochemical facility during and following an earthquake. In the area...
Spatial Analysis in Soil Dynamics and Earthquake Engineering
This Geotechincal Special Publication contains the papers presented by the invited speakers in the sessions on Spatial Analysis in Soil Dynamics and Earthquake Engineering held during...
Seismic in St. Louis
Following collapse of sections of the double-deck I-880 Cypress Viaduct in the 1989 Loma Prieta earthquake, the Missouri Department of Transportation initiated a seismic evaluation and...
Dampers Do the Job at Davis (Available only in Structural Engineering Special Issue)
Three recent earthquakes�the Kobe earthquake in Japan and the Loma Prieta and Northridge earthquakes in California�have caused engineers to take a much more serious approach to seismic...
Seismic Analysis and Design for Soil-Pile-Structure Interactions
Pile foundations are used extensively to support structures in seismic regions around the world. For years, geotechnical engineers have neglected to consider the interaction soil-pile...
Geophysical Exploration for Engineering and Environmental Investigations
The U.S. Army Corps of Engineers has prepared this Manual,
General Procedures for Conducting an Investigation
This section covers general procedures for conducting an investigation. Topics include lifelines and critical facilities to be investigated; the role of the team leader; getting started;...
Shear-wall Retrofit
With the effects of the 1989 Loma Prieta earthquake still lingering and another quake looming sometime in the future, engineers faced with retrofitting the Pacific Gas & Electric...
Seismic Solutions for Steel Frame Buildings
After the Northridge Earthquake, damage in steel moment resisting frame connections stunned engineers. Now those engineers are scrambling to find and test new kinds of connections. This...
Spotlight on Steel Moment Frames
Engineers' confidence in moment connections was shattered when damage was discovered after the 1994 Northridge earthquake. Such connections are now a hot subject for U.S....
Depth-Averaged Boussinesq Equations Applied to Flow in a Converging Channel
Supereritical flow in a contracting channel is simulated by numerically solving the 2D depth-averaged Boussinesq equations using a fmite-difference model DASH (Molls and Chaudhry 1995,...
Dam Foundation Erosion Study: The Design of a Sidewall Orifice for Simulation of a Free Trajectory Overtopping Jet
This paper describes the design of a sidewall discharging orifice for simulation of a free trajectory overtopping jet. A sidewall orifice discharges through the sidewall of a pipe. The...
SpatioTemporal Stochastic Open-Dhannel Flow
The de Saint Venant equations are solved as stochastic partial differential equations whose parameters (hydraulic resistance, bed slope, cross-section geometiy, inflow hydrograph, seepage,...
Rational Design and Operation of Packed Bed Adsorption Reactors
Design of packed bed adsorption reactors is based presently upon the parameter empty bed contact time (EBCT), a fallacious concept. The column wave front behavior, instead, should be the...
