Commuter Control
Traffic management systems are a relatively new way to expand the capacity of existing highways and to utilize new ones realistically. Several major systems have been in place and new...
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...
Truck Involvement in Fatal Urban Road Accidents in Australia
Trucks are over-represented (relative to vehicle numbers and vehicle-kilometers of travel) in fatal accidents. Those most at risk are occupants of other vehicles and pedestrians. Articulated...
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...
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...
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...
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...
Analysis of Tapered and Stepped Columns by Analogy to Cantilever Deflection
An analysis is developed for handling the buckling design of tapered and stepped columns with the aid of the so called 'amplification factors'. When these factors...
Optimum Design of Tapered Tubular Members
An algorithm for designing a tubular structural member with constant taper is presented. The design criterion is that the maximum absolute stress produced by a set of loading conditions...
Buckling Load of Tapered Columns
The basic tapered column with larger section in the center, is considered using Rayleigh-Timoshenko method. Column has linearly increasing Io with...
Buckling of Variable Cross-Section Columns
An approximate solution for the problem of buckling of variable cross-section columns, loaded by variable axial force is given, for several boundary conditions. Both the cross-section...
