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...

Design Issues in Steel Buildings
The Committee on Design of Steel Building Structures of the Committee on Metals of the Structural Division of ASCE was formed in 1981, with the express purpose of studying problems that...

Steel Girt Design
Procedures are presented for the design of light gage cold formed girts and hot rolled girts. The effects of continuity, sag rods, and wall sheeting are discussed. Design procedures are...

Floor Vibrations ? Tips for Designers
The purpose of this paper is to suggest a number of practical concepts which can be used to improve the performance of floor systems subject to occupant induced motion from either walking,...

Cold-Formed Z-Sections Under Axial Load and Bending
The use of cold-formed Z-section members as beam-columns presents some unique design problems which are not adequately addressed in the current design specifications. If these members...

Automated Load Capacity Determination of Cold-Formed Steel Compression Members
This paper presents an automated approach for the evaluation of the axial load capacity of nine cold-formed steel sections according to the latest AISI-1986 Cold-Formed Steel Specification....

Brace Connections for Ductility
Influence of connection design on the seismic behavior of welded bracing members made of double channels is studied in this paper. Shortcomings of commonly used connection details as per...

End Plate Moment Connections for Cyclic Loads
Three pilot tests of full size end plate moment connections under cyclic loading are discussed. In one of the specimens, the premature fracture of one of the inner bolts suggests the possibility...

Strength of Biaxially Crooked Jumbo Columns
The ultimate strength of axially loaded jumbo columns with biaxial initial out-of-straightnesses is analyzed by the finite element method. The analysis makes use of the measured residual...

Behavior of Single Angles Under Compression and Biaxial Bending
Angle struts are being used extensively as web members of trusses, bracings of buildings, and they are widely used as main members in transmission and lattice towers. Because of their...

Optimal Shape Design of Columns for Buckling
A procedure for the shape optimization of a column for prescribed buckling load is developed. The procedure uses a new analysis technique that enables the formulation of the optimization...

Notable Unbuilt Bridges
In the examples of unbuilt bridges discussed, many different ideas and concepts have been proposed. Most appear to be basically sound in nature, although rather innovative and daring....

Aestetics of Bridges Constructed by Dopravni Stavby, Olomouc, Czechoslovakia
A survey of bridge concepts built in recent years by the State Enterprise Dopravni Stavby, Olomouc that ranks among the largest building trade firms in Czechoslovakia. This firm chooses...

Pure Building
This paper outlines the need for building integration in the design of fabric structures by examining the different necessary components and how they fit together. It provides examples...

Beautiful Bridges and Highways in the West
This paper recounts 75 years of progress in the design of aesthetic bridges and highways in the west. Not a new idea, there are numerous existing examples showing that the goal of good...

Extensions of Finite Element Technology for Automated Design
The finite element method, by itself, is an efficient analysis tool with which we can judge the quality of a proposed design. However, by coupling finite element analysis with numerical...

Getting Finite Element Programs to Reason About Their Analysis Assumptions
Despite the spectacular improvements of finite element analysis programs, there has been no corresponding progress in the development of physical modeling and interpretation aids. The...

Representation of Strategic Choices in Structural Modeling
A major concern in structural modeling is the proper choice of tools to achieve stated objectives. Problem statements in structural analysis and design are usually made in fairly abstract...

Idealized Models in Engineering Analysis
This paper examines the roles of idealization and discretization in engineering analysis and design. Physical idealizations as commonly used in analysis and design are non-analytic in...

Object-Oriented Design of Finite Element Programs
This paper describes an implementation of the finite element method based on computational abstractions of both mathematical and engineering concepts. In contrast with conventional approaches,...
