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 Io 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...

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...

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...

Long-Term Buckling of Composite Columns
A consistent theoretical study of the creep buckling behaviour of viscoelastic laminated columns is presented. The problem is treated by means of the quasi-elastic method. The analysis...

Analysis of Slender Prestressed Concrete Columns
This paper briefly describes an analytical model developed to study slenderness effects in prestressed concrete columns and walls and predict the characteristics of such members over a...

Dynamic Response of a Building with Dual System
The paper presents the dynamic response of a 30-story building with dual system consisting of cross-bracing and beam-column moment resisting frames. Two types of beam-column connections,...

Optimum RC Member Design With Discrete Sections
This paper concentrates on the development of simplified yet effective algorithm for optimum reinforced concrete (RC) member design. After constructing the data base of predetermined reinforced...

Nonlinear Analysis for the Aseismic Strength of Highrise Steel Frame With Semi-Rigid Joints by Pseudo-Elastic Approach
This paper suggests that the direct stiffness method is still useful in dealing with the nonlinear analysis for the aseismic capacity of highrise steel frame while the Pseudo-elastic approach...

Deformability of Reinforced Concrete Members
A large volume of test data has been evaluated to establish deformability of reinforced concrete beams, columns, and structural walls in the inelastic range. Experimentally observed deformation...

Residual Capacity of Explosively Damaged Reinforced Concrete Columns
The results of load tests on explosively damaged reinforced concrete columns are presented. The method used to correlate an ultimate strength, laminar type of reinforced concrete analysis...

New Roof for an Aging Temporary
The wartime temporary design of a 1942 industrial building justified use of green timber for its roof trusses and higher than usual allowable design stresses. Some 45 years later, a new...
