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....
Salvaging the Zilwaukee
In 1982, construction of the Zilwaukee Bridge in Michigan was disrupted when the launching truss failed to hold a precast concrete segment near Pier 11N, severely deflecting the cantilever...
The Mile High Dream
For the 1986 Tall Buildings Conference in Chicago, a group of experts studied the implications of a mile high skyscraper to be built of concrete. It is 500 ft square at the base, designed...
Optimizing Drain Spacing and Depth Using Steady State Equations
A method is developed for minimizing the total cost of establishing relief drains by choosing appropriate depth and spacing of the drains. Solution graphs are presented for a wide range...
Restoration of Navy LTA (Lighter Than Air) Hangars
In 1942 and 1943 the Government constructed a series of 16 blimp hangars at ten Naval Air Stations along the east coast, west coast and gulf coast. The hangars erected in pairs housed...
Case Studies in Upgrading of Wood Trusses and a Heavy Timber Building
Three case studies in upgrading and rehabilitation of wood structures are presented. One case study relates to three 30m (100ft) span bowstring trusses that had to be cut at various span...
Epoxy Repair of a Glulam Beam
The repair of timber structures by epoxy injection techniques is a recently developed repair alternative. Theoretical and experimental studies have resulted in the formulation of design...
Alterations to Old Wood Building
In order to accommodate a new use, a request was made to remove bearing walls supporting the roof of a 42 year-old building and substitute timber posts. The existing nine-foot ceiling...
Record High Rise, Record Low Steel
The Bank of China, under construction in Hong Kong, will be the world's fifth tallest building. In spite of the extraordinary codes for that city�high winds, and high live...
Application of the BEM to Elastodynamics in a Three Dimmensional Half Space
The boundary integral equations (BIEs) are formulated for scattering problems of elastic waves by a cavity or a crack in a three dimensional half space. Two formulations based on the Green's...
Reliability Constraint on Optimum Design
The purpose of the paper is to emphasize the importance of the probability concern on optimum design work. The probability of failure of the structure can be considered as one of the optimum...
Optimization for Overall Stability
This paper synthesizes design of trusses for linear stability constraint as an optimization problem where linear stability is defined as a generalized eigenvalue problem and presents a...
The Rise of the Tall Building
The development of the high-rise frame in the U.S. was the result of a collision of many factors. The destruction of Chicago in the great fire of 1871 was one major factor in the start...
Experimental Assessment of Performance of Bridges
Among the papers in this book, five assessed the global bridge behavior and the three concentrated on bridge decks. The bridges assessed include prestressed steel plate girder and truss...
Parking Efficiency Through Shared Parking Concepts
Due to continuing demand for concentrated parking supply in our urban areas, developers and public agencies must devote a significant amount of their resources and energies to providing...
Concrete Space Frame Applied to an Arctic M.O.D.U.
The BOUYGUES experience in the use of concrete space frame technology for civil works and the application of this technique, combined with high strength concrete and prefabrication, to...
Multi-Truss Design for Tower
A modified structural steel system of outrigger trusses and belt trusses bolster the 54-story Equitable Tower West. Located in New York City, the building's structural system...
The Hybrid Arena
The University of North Carolina's new basketball arena at Chapel Hill combines steel and fabric in a dome whose design by David Geiger Associates is based on the principles...
Vehicle Sound Power measurement Using the Acoustic Intensity Method
The use of the two microphone Acoustic Intensity Method of obtaining accurate measurement of over-all sound power of large wheel loaders is described. This system is in operation, within...
Optimization Issues in the Design and Control of Large Space Structures
The optimization and identification issues which arise in the design and control of large flexible space structures are reviewed. The first paper examines the use of several different...
