Engineering Implications of Impoundment of the Indus River by an Earthquake-Induced Landslide
Historical records and physical evidence indicate that in the Himalayas of northern Pakistan a huge landslide dam was caused by an earthquake in 1840. The dam blocked the Indus River,...

Clean-up in the Rockies
The shallow aquifer flowing beneath the Rocky Mountain Arsenal, just outside of Denver, has become contaminated with a number of toxic substances. Until the arsenal can be cleaned-up,...

Dynamics of Fender and Rack Systems for Docking Ferries
A dynamic analysis of a ferry fender and rack system is developed based on the conservation of energy principle and Newton's laws of motion. The dynamics of the interaction...

Floating Bridges in Short-Crested Random Seas
Four large concrete floating bridges located in Washington State have been the subject of extensive analytical modeling for dynamic response to storm waves. The dynamic analysis of the...

Changes in Bridge Deck Flutter Derivatives Caused by Turbulence
This paper discusses some of the results of a wind tunnel study that tested the aeroelastic stability of section models in smooth and gusting flow. Wind gusts several times longer than...

Wind Loads and Building Response Predictions Using Force Balance Techniques
The use of force balance techniques to measure mean and dynamic wind loads on models of buildings and structures is discussed. Advantages of using force balance techniques over estimating...

Diffraction Forces on Axisymmetric Bodies
Use of a Green function satisfying the governing differential equation and all boundary conditions except those on the boundary of the structure yields an integral equation, when these...

The Atlantic Palace?Part II The Application of Wind Tunnel/Force Balance Techniques
A relatively new approach for determining overall wind-induced loads on a structure is described. This force balance technique is economical and flexible, and able to provide predictions...

The Atlantic Palace: Part I Structural System Selection Based on Wind Tunnel Testing
The location of the structure in a coastal area susceptible to high winds, the irregular shape and height of the building and the desire for more accurate wind loading and acceleration...

Experimental Studies, Structural Design and Full-Scale Measurements for the Columbia Seafirst Center
The Columbia Seafirst Center is a 76-story office tower located in downtown Seattle, Washington. It rises to a height of about 940 feet above ground and is the world's 10th...

Comparison of Predicted and Measured Dynamic Behavior of Allied Bank Plaza
Structural engineering aspects of a monitoring program to measure Allied Bank Plaza tower's dynamic response to wind are presented. In particular, field data developed during...

Damping Systems to Limit the Motion of Tall Buildings
Two types of damping systems have been used successfully in building applications - the Tuned Mass Damper, and Viscoelastic Damping Units. In the past, Tuned Mass Dampers were used in...

Disney Engineers Voyage to the Deep
The main show at the Living Seas Pavilion, part of Walt Disney Production's EPCOT Center, Lake Buena Vista, Fla., is a visit to a tropical coral reef deep under the ocean....

Design of Wharf Facilities, Guam, M.I., to Accommodate Difficult Site Conditions
A wharf facility currently under construction in Guam, Mariana Islands, for the U. S. Navy utilizes precast concrete box caisson construction to satisfy difficult site conditions. To reduce...

The Application of Computer Simulation in the Design of Marine Terminals and the Scheduling of Ship Traffic
This paper describes a software package which simulates the operations of marine terminals. The computer programs were designed to assess the effectiveness of the available design alternatives...

Terminal 18 Entry Facility?Port of Seattle
This paper presents a successful approach that was used in the planning, design, permit coordination, and expansion of the entry/exit facilities at Terminals 18 and 20 at the Port of Seattle....

Designing Marinas to Mitigate Impacts
The John Wayne Marina was permitted for construction only after certain design features were altered to accomodate major biological and water quality concerns. The moorage basin was relocated...

Marina Design and Environmental Concern
Research initiated by a Florida Cabinet Resolution of August 6, 1974, has generated two models for the evaluation of the impact of marina development on coastal waters. One, a complex...

Marina Flushing and Sedimentation
The paper discusses a one-dimensional circulation model for the marina. Tides are modeled as long waves and are assumed to be much longer than the marina. This circulation model is coupled...

Perforated Wave Barriers in Small Boat Piers
Perforated breakwaters can be used to reduce the energy and the height of waves entering small boat harbors. By not extending the breakwater to the bottom interference with littoral drift...
