High Strength Concrete - A New Material
In this paper, the material properties and structural member behavior of normal and high-strength concretes are summarized. The current ACI code recommendations are based on results of...

The Just-in-Case Factor
Computer analysis allows bridge designers to take a more precise look at the old structural principle of redundancy. No one can define redundancy, but everybody knows what it means. Two...

Arch Dams for Small Hydroelectric Sites
Approximate formulas are developed for the design of small arch dams. These designs, although conservative, frequently allow for economies over other dam types. Considered are: an approximate...

Design and Test of Cold Formed Steel Members
Latticed systems represent the most spread and low-cost solution for electrical trasmission towers, when ground conditions do not affect the design choice. Steel angles have been used...

Spring Stiffness for Beam-Column Analysis of Soil-Structure Interaction Problems
The objective is to provide a simple means of analytically combining a two-dimensional foundation with a beam-column structure so that the procedure can be used for preliminary design...

Nonlinear Analysis of External Prestressed Bridges
Finite element formulations for analysis of the overall response of concrete bridge girders prestressed with external tendons is described. The analytical procedure includes several nonlinear...

Practical Modeling of Bar Slippage in R/C Joints
A procedure based on the displacement method of analysis has been developed for analyzing the behavior of beam reinforcement crossing the interior beam-column connections under seismic...

Cyclic Energy Absorption by Reinforced Concrete
Results are presented on the basis of experiments conducted on conventional and steel fibrous reinforced concrete beams. The effects of the amount and nature of steel reinforcement and...

The Atlantic Palace: Part I Structural System Selection Based on Wind Tunnel Testing
The location of the structure in a coastal area susceptible to high winds, the irregular shape and height of the building and the desire for more accurate wind loading and acceleration...

Long Reinforced Concrete Columns
Papers selected by the Reinforced Concrete Research Council of ASCE. This collection contains 13 papers reporting the results of a series of studies,...

Some Applications of Fourier Series in Structural Optimization
This paper discusses the application of the method of truncated Fourier series to problems of structural optimization. It begins with a discussion of the range of the method which has...

Software for Optimum Design of Highway Bridge Beams
A software system for analysis and optimum design of welded plate beams subjected to AASHTO highway bridge loads and specifications is described. The system has the capability to design...

Computer Simulation of the Overload Behavior of Steel Multigirder Bridges with Cracked Girders
Various approaches of determining the structural response of steel multigirder bridges with cracked girders are presented. It is noted that linear finite element packages with three dimensional...

Evaluation and Upgrading of Wood Structures
Case Studies
The need to evaluate and upgrade existing wood structures stems from concerns of safety and serviceability. These concerns are caused for a variety of reasons which include plans for continued...

The Concrete Diagonal
Onterie Center in Chicago, Fazlur Kahn's last major structural design, is a companion in concrete to the diagonally braced steel John Hancock Center. It is a mixed-use building...

Spreadsheets: A New Design Tool
New techniques are developing which make computer programming easier. One new technique is spreadsheet programming for microcomputers. Two programs are presented which give a quick overall...

Stochastic Beams on Elastic Foundation
The finite difference method is applied to the second-moment analysis of beams on elastic foundation with random characteristics. The method is simpler than the stochastic finite element...

On the Design of Continuous Composite Beams
Methods of analysis and design of continuous composite beams are presented. Numerical analysis is used to determine the effective width of the slabs to be used in design. The influence...

Behavior and Strength of Stub-Girder Floor Systems
The paper presents a detailed evaluation of the behavior and strength characteristics of the stub-girder floor system. This is a composite girder and beam structure that integrates the...

Strength of Composite Beams under Seismic Loading
Effective width of a concrete slab of a composite beam is specified in various specifications, but their theoretical backgrounds are obscure. Originally, they must have been specified...
