System Identification Applied to Pseudo-Dynamic Test Data: A Treatment of Experimental Errors
A single-input single-output system identification technique, used to estimate the modal properties of a full-scale six-story steel structure tested within its elastic range by the pseudo-dynamic...
Comparative Seismic Response of Damped Braced Frames
The behaviours of braced steel building frames with friction joints and with eccentric bracing, under seismic forces, are compared. Nonlinear time history dynamic analysis is used. Friction...
Interaction Effects in Vertically Excited Steel Tanks
Following a brief review of the hydrodynamic effects induced by a vertical component of ground shaking in liquid-filled, circular, cylindrical, steel tanks that are rigidly supported at...
Bounded State Control of Structures with Uncertain Parameters
The control of linear systems in the presence of set constrained external disturbances has been investigated maintaining the states in a prespecified region by estimating the maximum reachable...
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...
Engineering Laboratories' Role in Quality
Quality construction of a quality design is one goal which Owners, Design Professionals, and Contractors can all agree is needed if the project is to be truly successful. The Engineering...
It's Only Visual Inspection (Welding Inspection)
Unless specified otherwise in the Contract Documents, Visual Inspection will be performed on all fabrication/erection welding for projects that utilize the Specifications for the Design,...
Development of Second Generation Plasticized Sulfur Binders as a Paving Material
Plasticized sulphur is produced when melted sulphur is reacted with selected hydrocarbons to produce polysulfides. These polysulfides help retain a 'polymeric'...
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...
The Parking Problem
Corrosion of parking garage decks has become a multi-billion dollar problem, caused primarily by deicing salts that seep into the concrete and attack reinforcing steel. Design and construction...
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...
Cold Regions Engineering
Engineers who plan, design, construct, operate and maintain facilities in cold regions must deal with all the concerns found in the more temperate areas of the world in addition to the...
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,...
Pavement?An Integral Part of the Terminal as a Container Handling System
A modern container terminal requires extensive areas of paving for stacking and moving containers, the provision of which often proves to be one of the most expensive single items, in...
U.S. Navy's First Double Deck Pier
The present single level concept of pier construction limits the pier-side service to the fleet. With the ever increasing requirements for utilities to the ships, and maintenance and training...
Construction Approaches to the Navy's Floating Pier Concept
The subject of this paper is a floating pier which is currently under evaluation as a more cost-effective solution for berthing Navy ships. This new approach to pier design was sponsored...
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...
Pavement Design for a Break Bulk Terminal Yard
This paper discusses the practical application of mechanistic pavement design principles for a proposed 8. 1 ha break bulk cargo storage yard that is part of the Port of Portland's...
