Avoiding Transportation Future Shock
Seattle, Washington's regional government planning group, called METRO, has undertaken a future scenarios approach to transportation planning. Working with an outside panel...
Assessing the Role of Regulation in Urban Goods Movement
While economic regulation per se is becoming virtually non-existant, other forms of regulations which result in finite and measurable economic impacts continue on -- and indeed are proliferating....
Dallas Urban Goods Movement Changes-The Decade After
In the 1970's, the City of Dallas undertook an urban goods movement (UGM) planning project that resulted by the end of the decade in far reaching changes in the process, particularly...
Economic Impact of Alternative Downtown UGM Strategies
In downtown Dallas, four strategies have been tested: consolidated public truck terminals; provision of off-street loading space in individual buildings, under ordinance; curb space management...
Load-Permit Truck Operations in New York State
This paper presents the results of a survey of indivisible-load permit vehicle operations in New York State. The survey was conducted in the context of an investigation into the impacts...
Superskycraper
The design for a hypothetical 142-story building advances te real-world challenge for taller and taller superskyscrapers. To be located on the riverbank in Chicago, it is 1,745 ft tall...
Analyzing in 3D
Suggestions for modeling and evaluating three-dimensional (3D) structures are presented. These suggestions are based on the authors' sixteen years of day to day involvement...
An Overview of Structural Reliability Methods
Recent developments in structural reliability theory and better availability of load and strength data suggest that reliability-based design (RBD) methods should be considered as a practical...
Transmission Line Structure Loading
This paper outlines specific procedures for determining loads on transmission line structure systems that can be used in the reliability based design or assessment of components of these...
Assessment of Conductors
This paper deals with the mechanical integrity of conductors after several years in service and discusses current innovative conductor designs which benefit the structural designer working...
Cambering of Steel Beams
Cold cambering with force in the fabrication shop is an effective and economical method of compensating for deflections of composite beams. Typical beams should be cambered for dead load...
Engineering Design Concerns Regarding Steel Fabrication
The precise fabrication of structural steel pieces is an essential part of the process leading to the satisfactory erection and connection of the individual steel elements into the final...
Six Story Tubular Atrium
The author designed an atrium structure with two stair-stepped atriums placed at 45? to the tower 'Figueroa at Wilshire' in Los Angeles, California. This structure...
The Fabrication and Erection of the Minneapolis Convention Center
A new convention center is part of the City of Minneapolis' successful plan to maintain an economically strong downtown core. It is the latest addition to a list of civic...
Changes in Tubular Design Codes
This paper summarizes a number of changes in design provisions for tubular structures that have recently been adopted. These are the result of a number of research advances concerning...
Behavior of Plates Under Partial Edge Loading
This paper addresses one of the common problems in designing thin-walled members, the ability of the shape to accommodate in-plane concentrated loads. Specific areas in which the problem...
Stability of Plates Under Eccentric Edge Loads
A linear finite element analysis was conducted to study the stress distribution in the web and the flange when the beam is subjected to a patch load applied in the plane of the web or...
Longitudinal Impact Loading of Transmission Towers
A scale model has been developed to study a containment failure design concept for longitudinal (along the direction of the conductor) impact loading of electrical transmission structures....
Sizing Techniques for Lateral Bracing
Techniques for determining the size of lateral bracing members in multi-story steel buildings are presented and discussed. Because the design of such bracing is usually controlled by deflection...
Double Angle Bracing Members
It has been pointed out that when a single line of bracing is used, the member is usually made from structural tubing. It has been suggested that when the loads are not too great, consideration...
