Active Control of Distributed Parameters Structures by Pointwise Control Actions
Several methods have been offered to control a structure. These methods are the optimal control, the pole assignment, the independent modal space control, and the direct velocity feedback....
Application of Modern Control Theory for Building Structures
Active control systems can be used to reduce the effect of strong-motion earthquakes. During the past two decades, various approaches have been applied to find the optimal control law....
An Experimental Study of Active Structural Control
An experimental investigation is made concerning the possible application of active control to structures under seismic excitation. The experimental facilities and structural model are...
Dynamic Response of Highway Guardrail Post Foundations
The highway departments use two types of guardrail posts: a circular wood post and a steel W6 multiplied by 8. 5 post. The current specifications require the steel post to be placed in...
Dynamic Behavior of Full-Scale Wood Diaphragms
Experimental testing of full-scale wood diaphragms has been performed at Washington State University to determine basic dynamic properties. Ten diaphragms, including walls, floors, and...
Response of Underground Pipelines to Dynamic Loads
The results of an investigation of the forced response of an underground pipeline due to dynamic loads are presented. The pipe is modelled as a linearly elastic shell element and the surrounding...
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...
A Stochastic Source Spectrum for Engineering Application
The solution of a point source (double couple) combined with K. Aki/A. S. Papageorgiou's stochastic source model is used to establish the power spectrum at the acceleration...
Structural Dynamics in Hurricanes and Tornadoes
The random fluctuations of wind gusts produce dynamic interaction with structures. The objectives of this paper are to identify distinguishing differences in hurricane and tornado winds...
Procedures for Predicting Settlements in Sands
In many cases, the prediction of settlements of footings on sands involves use of empirical rules. Although many approaches are reported in the literature, the relative accuracy of these...
Settlement of a Reactor Containment on Sand
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...
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...
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...
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...
Financial Analysis of Port Facilities
This paper describes a spreadsheet-based structure for financial analysis of port facilities and services, designed for use as a planning tool by non-specialist port managers. The paper...
Port Master Plans and Feasibility Studies
Port projects are cost-intensive long-life irreversible assets, and developing countries particularly limping with resource constraints could not afford the luxury of short-sighted defective...
