NEUROFLOOR: A Flooring System Selection Neural Network
A back-propagation neural network (BPNN) has been trained to help building designers and engineers in designing or analyzing steel bar joist flooring systems. The NEUROFLOOR BPNN allows...
Computer Aided Experiments for Truss Structures
It is quite difficult to investigate structural mechanical properties by full scaled structure experiments. Consequently, an experiment using a reduced scale model is generally performed....
Secondary Member Contribution to the Behavior of Damaged Multigirder Highway Bridges
This paper examines the effects of secondary members (cross bracing and diaphragms) on the prediction of the response of damaged simple span steel multigirder bridges. Extensive analytical...
After the Blast
On February 26, 1993, a bomb exploded in an underground parking garage beneath the World Trade Center, killing six, causing hundreds of millions of dollars in damage and leaving a crater...
Highway Speed Radar for Pavement and Bridge Deck Evaluation
Radar has been developed as an economical alternative evaluating pavement layer properties and estimating quantities of deterioration in bridge decks. These highway applications are based...
Corrosion Model for Concrete Structures
The high basic environment created by concrete pore water protects the reinforcing steel from spontaneously corroding. Chloride ions destroy the passivity of steel in concrete and the...
Automated Generation of NBI Reporting Fields from Pontis BMS Database
Methods to generate National Bridge Inventory (NBI) condition ratings for deck (Field 58), superstructure(Field 59), substructure (Field 60) and culvert (Field 62) from the bridge database...
Assessment of Guideway Systems for Maglev Applications
Recognizing the potential benefits of MAGLEV high speed mass transportation systems, three innovative guideway systems have been evaluated herein from the viewpoint of: (1) loads and performance...
Making the Leap
Over the past decade, computers have become as much a part of the engineering field as concrete and steel. But bringing a firm into the information age can be complicated and expensive....
A Wave-Energy Dissipation Structure for Shore Protection and Beach Generation, Recovery, and Stabilization
WAVEBLOCK a steel reinforced concrete modularized structure designed to dissipate the energy of saline and freshwater waves is described. The modularized structure, which weighs upwards...
Application of Composite Members to Marine Structures in Japan
Composite structures combined steel plates and reinforced concrete with shear connectors have been applied to port and harbor facilities in Japan since the early 1980s.Composite structures...
Steel Penstocks
Lead is a Four-Letter Word
New regulations and strict enforcement make it difficult and expensive to remove lead-laden coatings from steel structures. Lead-based primers and paints are not considered hazardous as...
Closing the Loop
The 5.1 mi Cooper River Bridge, the longest in South Carolina, completes the I 526 Mark Clark Expressway around Charleston. It is a two-way, four-lane structure with the capability of...
Local Scour at Bridge Piers in Alberta?Case History
A two span steel truss bridge with a rectangular concrete central pier was built over the Oldman River near Brocket in south-west Alberta in 1954. Initially the bridge was built square...
The EUR Water Station in Rome?Italy
The paper deals the new steel Water Centre realized by ACEA in Rome. The Water Station is destined to manage the water consumption of around 500,000 inhabitants with an output of 3,900...
New Developments in Eurocode 4
The European Community has initiated the preparation of a set of harmonized structural codes. Eurocode 4 is the code for the design of composite steel and concrete structures. The first...
Composite Beams: Redistribution, Reliability, and Lateral Buckling
Research relevant to three aspects of the design of composite beams for ultimate limit states is summarized. These are: the redistribution in continuous beams and in framed structures...
Highlights of the New ASCE Standards on Composite Deck Floor Slabs
This paper presents highlights of the newly approved and printed ASCE Standard on the design and construction of composite floor deck slabs utilizing cold-formed steel. In 1992 four documents...
