In this paper, predicted and observed settlements are presented for the reactor containment structure of the Beaver Valley Power Station - Unit 2, Shippingport, Pennsylvania. The Beaver...
Dynamic Response Correlation Using Simplified Models
A simplified model for building response which has a W. Ramberg-W. R. Osgood hysteresis is developed in a discrete sense. It is then used to evaluate the response of an instrumented, bearing...
Large Scale Testing Facility for the Evaluation of Structural Systems Under Critical Loads
The Charles Lee Powell Structural Systems Laboratory at the University of California, San Diego, provides, with a 50 ft. high reaction strong wall and a 120 multiplied by 50 ft. box girder...
Performance of an Earthquake Excited Roof Diaphragm
The objective of this paper is to study the earthquake performance of the roof diaphragm of the West Valley College gymnasium in Saratoga, California through a complete set of 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 in Tall Buildings: Its Variability and Treatment in Design
Increasingly, damping is being recognized as an important factor in the design of structures. It is at the same time a property which is relatively poorly defined, more acquired than engineered...
Design of Viscoelastic Dampers for Columbia Center Building
To reduce the dynamic response of a building with a given height and plan area to wind load, aside from inherent damping of the building, the designer has a few options available to him/her....
Performance of Viscoelastic Structural Dampers for the Columbia Center Building
Vibratory motion of structures such as buildings, bridges, and floors can be reduced by the use of viscoelastic (V. E. ) dampers. Such dampers transfer part of the vibratory energy of...
Blasting Densifies Sand
Constructing the Jebba Dam on Nigeria's Niger River required in-place densification of large volumes of loose sand to record depths of up to 131 ft. Vibrocompaction was used...
Monitoring a Bridge's Pulse
The Sunshine Skyway Bridge, which collapsed in 1980, is being replaced by the Florida Department of Transportation. The new Sunshine Skyway Bridge, which spans Tampa Bay between Bradenton...
Alternative Dispute Resolution
Usually it takes far less money and time to resolve a construction dispute if a lawsuit and court trial can be avoided. In the mini-trial, te two or more parties agree to radically reduce...
The Public/Private Condo
A 20-story office building in Chicago was built on publicly owned land under a condominium arrangement that allowed a developer full ownership of air rights over and above the 100,000...
Complex Tower Meets Quake Code
A Los Angeles building consists of a triangular 23-story office tower stacked on top of an 11-story rectangular parking garage. The dual-shape is unique in seismically active southern...
Computer Cuts Tower Steel
Two computer programs developed by Lev Zetlin Assoc., New York City, revealed that some of the steel in what will be Philadelphia's tallest building, One Liberty Place, was...
Roof Membranes: New Systems, New Problems
Market trends in roof membranes are described; most important is the use of single-ply membranes of rubber or plastic in the past decade. A swing to modified bitumen membranes is predicted...
Electronic Computation
The papers included in this book were presented during the thirteen sessions of the Ninth ASCE Conference on Electronic Computation. Topics addressed represent a wide spectrum of computer...
Innovations in the Design of Electrical Transmission Structures
New concepts are being advanced for the design of electrical transmission structures. The papers in this book cover the following: weather-element loading conditions, structural options,...
An OCEANWHEEL Breakwater
The compression wall and tension spoke structural system (OCEANWHEEL) transfers lateral loads from sea surface to seafloor efficiently. It promises a wide variety of uses beyond the described...
Port Expansion of Eastport, Maine
A recent pier expansion now allows Eastport to provide 40 feet of water at low tide. The pier expansion consists of a concrete-decked steel pipe pile-supported extension to an existing...
