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...

Composite Floor Vibrations: Predicted and Measured
Several steel composite floor systems of relatively long span trusses for a number of high rise structures in the Chicago area have been subjected to field measurements to evaluate their...

Behavior of Cold-Formed Steel-Concrete Composite Beams
An experimental investigation was conducted at California State University - Long Beach to study the structural behavior of composite beams made of thin-walled cold-formed steel stiffened...

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...

Polypropylene FRC In Steel Deck Composite Slabs
Engineers, testing laboratories, universities and metal deck manufacturers have studied polypropylene fiber reinforced concrete (FRC) and compared the results with similar slabs reinforced...

Polymer Concretes
Polymer Concrete (PC) is prepared by using polymeric materials to bond inert aggregates in a fashion similar to that of Portland Cement in the preparation of Portland Cement Concrete (PCC)....

Review of Composite Analysis Methods for High Temperature Applications
This paper addresses a number of unique problems encountered in the stress analysis of high temperature composite materials. The materials used as structures subjected to temperatures...

Fiber Composite Materials in an Arctic Environment
This paper summarizes a study on the behavior of light-weight structural composite materials in cold environments. Results are presented for two composite materials: fiberglass-epoxy and...

Development of High Strength Composite Cables
Fiber reinforced composite materials offer significant advantages over conventional materials, for such factors as corrosion resistance, lighter weight, and higher strengths. These advantages...

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...

Structural Considerations in Design and Construction Process of a 25 Story Office Building
This paper introduces an example in which a steel office building of 25 stories above the ground was constructed employing innovative techniques. One of them was the use of precast concrete...

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...
