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...
Evaluation of the Rotation Capacity of Wide-Flange Beams Using Shell Finite Elements
Numerical simulation can be useful for planning of experimental tests, performance of parametric studies, and achieving an understanding of complex three-dimensional behavior that may...
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...
Stability Analysis of Steel Compression Members by a Modified Finite Strip Method
The method of structural stability analysis utilized in this paper is a combination of the classical bending theory and the finite strip method. Combining the assumptions of traditional...
Hysteresis Studies Including Post Buckling of Angle Web-Members for Truss-Type Girders
The paper presents analytical studies of the buckling capacities and hysteresis behavior of angle-web members of truss-type girders. The eccentricity between the loading point and the...
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...
Stability Analysis in Bracing and Support Design
A post-buckling stability analysis is carried out for struts with multiple elastic lateral supports. Both hinged-end and fixed-end conditions are considered. A criterion of sufficient...
