R/C Columns Under Axial and Bi-Directional Lateral Loads
The reliability of a model, called a multi-spring model, was examined to simulate the observed response of reinforced concrete columns subjected to varying high axial loads and bi-directional...

Dynamic Response Analysis of Three-Dimensional Beam-Columns
This paper describes a methodology for dynamic response analysis of three-dimensional beam-columns, whereby an elastic force's axial-flexural interaction is modeled with stability...

Seismic Retrofit of Highway Bridge Structures
The California Division of Structures began its column retrofit program in 1986. This program is a supplement to the earlier superstructure retrofit program. Analysis and design concepts...

Lifeline Design of Bridges
An analysis and design procedure is presented for retrofitting steel girder bridges that may experience the loss of a pier or column. Multispan and continuous grider bridges are treated....

Reliability of Highway Bridge Columns Under Earthquake Loading
Seismic design procedure for highway bridges normally specify that any inelastic action be confined to the columns. Concrete bridge columns are usually designed to resist an elastic force...

Structural Reliability of Wood Beam-Columns
A formulation for reliability-based design procedures of wood columns and beam columns is presented. The load carrying capacity of these structural members is obtained using a non-linear...

Reliability of Steel Columns Subjected to Buckling?Comparison of International Standard Codes of Design
Standard codes of design represent the phenomenon of buckling by means of a curve taking into account random structural imperfections. The author suggests a probabilistic method to evaluate...

Reliability Analysis of Axially Compressive Members
In the steel structure design code (TJ17-74) in China, a single curve was adopted for designing axially compressive members and the reliability of the column analyzed previously was based...

Inelastic Stability of Thin Walled Metal Tubes Under Cyclic Loading Conditions
This paper is concerned with an experimental investigation on the inelastic stability behavior of thin-walled tubular specimens of steel, aluminum and stainless steel, under cyclic loading...

Bibliography of Steel Columns
This book, which was prepared by the Committee on Compression Members of the Structural Division of the American Society of Civil Engineers, attempts to provide a complete bibliography...

Structural Details: Is Anything Missing?
While actual failure of a structure is uncommon, many projects have less publicized, detailing-related difficulties involving rework, changes, clarifications, and increased costs. If the...

Haunches and Hangers
The $210 million VA Medical Center at Houston features a structural system as innovative for the 1990s as the interstitial space concept was in the 1960s. The medical center, designed...

Effect of Imperfections on Structural Performance
This paper briefly describes the effect of initial crookedness and residual stress on the behavior of steel members. Both imperfections are unavoidable consequences of modern fabrication...

Toronto Skydome Retractable Roof Stadium?The Roof Concept and Design
The Toronto SkyDome is a first of its kind sports stadium with a retractable roof which results in, essentially, a fully open air stadium with the roof fully retracted. This unique roof,...

Changes in Tubular Design Codes
This paper summarizes a number of changes in design provisions for tubular structures that have recently been adopted. These are the result of a number of research advances concerning...

Effective Length Factors for Type-PR Frame Members
The effects of PR-Type connections and loading arrangement on frame stability and the effective length factor of columns are evaluated for portal frames and three-story three-bay frames...

Elastic Stability of Non-Prismatic Columns
A matrix analysis technique for determining the elastic buckling loads for columns of general form is presented along with several numerical examples. In this technique, a non-prismatic...

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...

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 I_o with...

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...
