Seismic Behavior of Built-Up Bracing Members
The influence of stitch design and local buckling on the seismic behavior of welded bracing members made of double angles is studied in this paper. Performance of boxed configuration with...

Simple Methods for Design of Steel Gusset Plates
This paper presents two simple methods for design of steel gusset plates. In the first method, the wedge theories are applied to establish state of stress in steel gusset plates. In the...

Preliminary Design Considerations for Flat Deployable Structures
Deployable structures are prefabricated frames that can be stored in a compact configuration, and can be easily deployed into a large-span, load-bearing space structure. The interest in...

Trends in Development of Steel Space Structures in Japan
Trends in recent development of steel spatial structures in Japan are reviewed. Starting from reviewing early development after the World War II, structural systems such as pyramidal roof,...

Some Examples of Latticed Structures in Spain
Since the middle of the last sixties latticed structures have extensively been used in Spain to cover different large areas as factories, churches, marketplaces, exhibition palaces etc....

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...

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...

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....

Seismic Response of Flexibly-Connected Steel Frames
The response of typical low-rise steel building frames designed by the 'Type 2 Construction' method to moderate earthquakes is examined. Such frames are often...

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...

Stablity Considerations in the New E&CS Building
The new Engineering and Computer Science (E & CS) building at California State University, Sacramento (CSUS) is a five-story structure characterized by two shear walls in the east-west...

Tripping and Strength of Asymmetrical Plate Stiffeners
Tripping (lateral-torsional buckling) of symmetrical or asymmetrical plate stiffeners can be analyzed by using differential equations or energy formulation. An analytical study is reported...
