RC Beam-Column Element for Nonlinear Frame Analysis
Recent studies have shown that beam-column finite elements that enforce equilibrium rather than compatibility along the element are better suited for the description of the strength and...

Flange Local Buckling and Behavior of I-Sections
A simple kinematic model is proposed to determine the locally buckled shape of the compressive flange plate of I-sections subjected to pure bending or bending combined with axial thrust....

Finite Element Analysis of Shear in RC Girders
Two complementary approaches are presented to model the shear behaviour of reinforced concrete structures. A local one, based on a probabilistic modelling of cracking, accounts for local...

Checking of CAD Drawings for Fabrication Issues
Communication between the fabricator and engineer is crucial to the production of an economical, safe, and functional steel structure. However, the transfer of information between involved...

Steel Detailing Neutral File from Modeling Software
Today's generation of computer graphics applications used for the purposes of modeling industrial structures can now transmit engineering electronic data to other downstream functions....

Fast Monte Carlo Simulations and Safety Index Checking
This paper presents recent techniques which require a small number of simulations to assess the structural reliability. They combine both the concept of importance zones in the random...

Storage Tanks: Going Above Ground
Until just a few years ago, the traditional replacement for a leaking underground storage tank was a new UST. But in September 1988, EPA finalized new regulations for UST systems containing...

Rehabbing Bridges Under Traffic
Four urban examples demonstrate how an owner's decision to keep it open during rehabilitation construction forces the designers to contend with an extra set of problems. Reanchoring...

Modular Evolution
The construction industry typically thinks of modular steel bridges in terms of the World War II vintage Bailey Bridge. The Bailey Bridge was designed to be quickly deployed to replace...

A League of Their Own
New baseball stadiums in Cleveland and Arlington, Tex., opening in April 1994, combine the nostalgia of traditional ballparks with state-of-the-art site planning and structural engineering....

Lightweight Concrete for a Segmental Bridge
Structural lightweight concrete can help increase the stiffness and decrease the mass of a bridge; both are qualities that make the structure more likely to survive an earthquake. Ordinarily,...

An Object-Oriented Approach for Reinforced Concrete Design
The use of the object-oriented programming approach in developing applications for the analysis and design of reinforced concrete members is discussed. Two object oriented programming...

Nonlinear Analysis of Structural Frameworks Using Supercomputing Techniques
Applications of vectorization and the parallel processing technique of multitasking in the elastic nonlinear analysis of building frameworks are presented. The proposed algorithm is implemented...

Evaluation of Software for Analysis and Design of Reinforced Concrete Structures
A study to verify the accuracy of two structural analysis and concrete design programs and to evaluate their functionality was conducted. The evaluation was based on a comparison of results...

Analysis of I-Girder Highway Bridges
Analysis of a bridge superstructure is complicated by the general geometric and loading conditions. Presented in this paper are three dimensional finite element modeling techniques used...

Bridge Rating Using Influence Surface for Curved Bridge Structures
A fairly sizeable number of curved steel bridges in Louisiana need to be rated and influence lines required to be stored. A methodology is developed and rating procedures are established....

Computer Analysis of Continuous P/C Highway Bridge Girders with Variable Depth
A computational procedure and associated computer program were developed for the analysis and design of P/C continuous beams with variable depth. Using this program, continuous girders...

Discrete Modeling of Soil-Structure Interaction Under Dynamic Loading
A proposal of discrete modeling useful to describe behavior of structures burried in the ground under air explosion is presented. In the modeling emphasis is laid on determining the space...

ESPADD.BR: Expert System Producing Automated Designs and Drawings for Bridges
This paper presents the logic and methodology used in developing an automated software system for designs and drawings of bridges. Its primary purpose is to design and draw highway bridge...

Characteristics of the US Highway Bridge Population
Characteristics of US highway bridges are summarized, and conditions of national, regional, and state bridges are analyzed with respect to structural deficiency. The overall patterns in...
