Tests on Brace and Link Connections for EBFs
This paper describes recent test results on the behavior of selected connections for seismic-resistant Eccentrically Braced Frames (EBFs). These tests provided data on the performance...

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...

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...

Lateral Buckling of Beams: General Considerations
The paper presents a solution for the elastic, lateral-torsional buckling of beams under unequal end moments using Worthington's method of superposition of modes involving...

Portal Frame Stability with Nonproportional Loads
An inelastic theoretical study of the effect of various load paths is conducted on the in-plane behavior of an imperfect portal frame with flexible joints. The loading consists of concentrated...

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...

Optimized Wall Thickness of Shells of Revolution
The aim of this paper was to develop a concept for the design of shells of revolution with different Gaussian curvature using a simplified finite element buckling analysis. A cooling tower...

Manipulation of Shell and Fabric Structure Form
Fabric structures and concrete shells are readily compared because of their curving shapes and the apparent structural derivation of their forms. Every fabric structure includes compression...

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...

Original Formulation of the Finite Element Method
Following a brief summary of the 1952 state of the art of structural analysis, the paper describes the circumstances that led to the formulation of the finite element method by members...

Major Advances in Finite Element Model Technology
The evolution of finite elements is traced from the viewpoint of finite element shape functions and element-related techniques. Particular emphasis is placed on the isoparametric element,...

Numerical Methods for Solution of Finite Element Systems
A personal summary of solution methods for the static and dynamic analysis of finite element systems, which have been developed during the past 30 years, will be given. Numerical techniques...
