Behavior of Externally Confined Concrete Columns
This paper investigates the feasibility of strengthening of seismically deficient concrete columns with high-strength fiber composite straps. The concrete columns will be externally confined...
The Crown and the Curtain Wall
Crowning the complex curtainwall of an 870 ft concrete tower with a 150 ft high crown of aluminum masts in concentric rings above the 60th floor required ingenuity and extraordinary cooperation...
Seismic Hazards in the Eastern U.S. and the Impact on Transportation Lifelines
In the eastern US seismicity is low, hazard is moderate, and risk is quite high, especially in metropolitan regions with vulnerable transportation systems typically not designed to resist...
Evaluation of Seismic Vulnerability of Highway Bridges in the Eastern United States
For high risk seismic zones such as California, the state-of-the-art in earthquake resistant design for new highway bridges has been well advanced, especially since the damaging 1971 San...
Engineering Pre-engineered Buildings
Pre-engineered buildings have become more sophisticated. There are several manuals and guides on how to engineer the so-called pre-engineered structures, but none are complete. There are...
Design Loads for Sloshing in TLP Pontoons Tanks
Impact of fluid inside the Auger TLP ballast tanks on tank walls was investigated and changes made to the structural design in an accelerated fashion through the use of model testing....
Nonlinear Wave Runup on Large Circular Cylinders
Various design methods for computing nonlinear wave runup on a large-diameter circular cylinder are presented. First, empirical correlations are developed between the observed maximum...
Computer Aided Design for Deep Water Offshore Risers
This paper describes a software package (OTRC-Riser-91) that was developed under the sponsorship of the Offshore Research Technology Center that is funded by the National Science Foundation...
The Mother of All Resilient Structures: Fixed-Base Tower in 3000-Foot Water and Some Outstanding Issues
This paper describes design and development work for 40- to 80-well fixed- base - yet compliant - towers for 2000- to 3000-foot water depths. Technical issues which are covered include:...
Design of Tension Leg Platforms: A Knowledge Based Approach
Tension leg platforms (TLPs) are floating compliant platforms designed for deep water offshore hydrocarbon production. Only a few TLPs have actually been built, but others are currently...
Wave Effects on Offshore Structures?Some Recent Research
The present paper summarizes methods of estimating wave effects on offshore structures, and highlights a selection of recent related research. Initially, certain aspects relating to the...
Re-Qualification of Offshore Platforms
Older platforms that are being re-qualified for extended service involve many technical problems that are unlike those associated with design of new platforms. Procedures to help resolve...
Reliable Design-Wave Force Predictions for Seabed Pipelines
The results of three separate field research projects have been pulled together to provide a design formula for maximum wave-induced horizontal force on a submarine pipe. This broadly-applicable...
The SIMBAT Software Package for Stochastic Interpolation of Ocean Wave Kinematics as an Aid in the Engineering Design of Large Floating Structures
Geostatistical techniques of nonconditional and conditional simulation are used in a new public domain computer software package, named SIMBAT, to stochastically interpolate ocean wave...
Hydraulic Design of Offshore Breakwater in Sergipe, Brazil
A Petrobras (Petroleo Brasileiro S.A.) marine terminal was recently constructed in Sergipe, Brazil (Figure 1). The offshore breakwater was initially designed in a conventional way, but...
Experimental Research on Groyne Stability Under Very Oblique Wave Action
Most of the experimental research concerning the stability of coastal structures is focused on normal wave incidence. However, many of these structures are subject to waves which run predominantly...
Dynamic Design of Deepwater Bottom-Founded Towers
This paper traces the development of dynamic design techniques for deepwater bottom-founded towers by the following: the classification of bottom-founded towers as either `stiff' or `compliant';...
Internationalization of Engineering Professions
The most salient features impacting the development of our deepwater frontier areas are considered. The areas of higher potential for deepwater reserves are identified. The integrated...
Piles Under Dynamic Loads
This proceedings,
RCC at 10
Tens years after the first roller-compacted concrete (RCC) dam in the U.S.�the 169 ft high Willow Creek Dam in Oregon�was completed, the method has gained wide acceptance around the world...
