Flexibility of Steel Seismic Moment Connections
Relevant Berkeley experimental results are critically evaluated to determine the flexibility of W18 W24 beam joints with and without stiffeners and/or doubler plates. The paper discusses...

Research Needs for Extant Iron and Steel Buildings
A brief review of iron- and steel-making processes is background for the development of shapes and codes. Sources of information for the condition assessment of iron and steel buildings...

Structural Integrity Assessment of the Flexible 870 Advanced Design Bus
The Grumman Flxible 870, a lightweight advanced design urban bus, entered service in Atlanta, GA in 1978, and some 2,800 of these buses were in service nationwide by 1980. In the autumn...

Restoring the Capitol's West Front
After 25 years of debate, preservation (rather than extension) of the West Front of the U.S. Capitol building in Washington, D.C. has begun. A network of stainless steel rods is being...

Romanesque Reused
When Union Station in St. Louis, Mo. was built in the 1890s it was the world's largest railroad station. Having been abandoned by the railroads in the 1970s, it was reopened...

Clearing the Decks
Cathodic protection, an electrical-chemical process that prevents corrosion of steel rebars on bridge decks, is rapidly gaining acceptance by highway engineers and state highway departments....

Composite and Mixed Construction
Steel and reinforced concrete are frequently combined in composite or mixed structural systems. This combination generally results isn greater economy and safety than could be achieved...

Specifications for the Design and Construction of Composite Slabs and Commentary on Specifications for the Design and Construction of Composite Slabs
Composite slab construction is defined as a system comprising normal weight or lightweight structural concrete placed permanently over cold-formed steel decking in which the steel deck...

Low Cement Content High Strength Concrete
The fundamental objective of this research project was to develop mix design information for structural grade concrete using high fly ash content. The fly ash used in this project was...

Advances in Fiber Reinforced Concrete
The idea of using strong discontinuous fibers as reinforcement for concrete seems to have been both a seduction and a challenge to many civil engineers. Adding the reinforcement to the...

Effect of Steel Fibers on the Cracking Behavior of Reinforced Concrete Continuous Beams
A research program was conducted with the aim of studying the cracking behavior of reinforced concrete continuous beams, as it is affected by using different combinations of main steel...

Rational Design of Beam-Columns in Steel
The paper discusses the procedure as currently recommended in the AISC Manual for selection of beam-columns in steel and points to the inadequacy of this procedure for quick convergence...

Advances in High Strength Concrete,
The technology for producing field placeable concrete with a 28 day compressive strength of 10,000 psi has been available for many years. With the recent use of microsilica as an additive...

The Transit Industry Microcomputer Exchange Support Center
The Transit Industry Microcomputer Exchange Support Center has been in existence for nearly three years. This paper describes the reasons for establishing the center, its current activities,...

Connection Flexibility and Steel Frames
The papers included in this book introduce and present methodologies for the analysis and design of frames which take into account the effect of joint flexibility on the response characteristics...

Rehabilitation, Renovation, and Reconstruction of Buildings
This document constitutes the proceedings for a National Science Foundation funded workshop to discuss research needs pertaining to the buildings side of infrastructure. It includes discussion...

Structural Design, Cementitious Products, and Case Histories
The papers in this book represent deverse topics in structural engineering. In design of beam-columns by the AISC interaction equations, it is demonstrated that an inadequacy exists when...

Slashing Tunnel Costs
The second U.S. application of the New Austrian Tunneling Method at Washington D.C.'s Metro system is described. The innovative method has been used overseas, but American...

Tunneling a Bridge
Linking an addition to the Georgia World Congress Center in Atlanta required a pedestrian tunnel through a railroad embankment 100 ft wide and 40 ft high, with no disruption of train service...

Advances in Short Span Steel Bridges
Applying recent research to the design of short span steel bridges can lower their cost and maintenance. Such research involves improved limit state criteria, more uniform lateral load...
