Steel Girder Bridge Sets Record Length
The Veterans Memorial Bridge at Ottawa, Ill., is the longest plate girder, stringer type bridge in the country with spans of 385, 510 and 305 ft. Value engineering played an important...
Bascule
The Columbus Drive Bascule Bridge in Chicago is one of the largest bascule bridges in the world with a 270 ft. span and 1l0 ft. width. Four welded steel box girders support each of the...
Tension Tests of Containment Wall Isolated Liner Plates
Two tests were conducted using an approximate 2:1 ratio of hoop to meridional load. This simple load ratio is a gross approximation of the liner plate loading in a containment subjected...
Structural Performance Predictions for Liner Plates on Nuclear Facilities
The history of the use of liner plates is presented. It is shown that the liner plate can be buckled, and can be bonded or not bonded to the concrete. The buckled plate usually has bending...
Simplified Design of Flexible Expansion Anchored Plates for Nuclear Structures
The following two phases of the design of expansion anchored plates are discussed in this paper. a) Initial Design. b) Reassessment of as-built conditions. Initial design refers to the...
ACI 349 Embedments: Code Provisions and Methods of Analysis
Steel embedments form the critical link between steel and concrete structures. Appendix B of ACT 349, Code Requirements for Nuclear Safety Related Concrete Structures, specifies the ultimate...
State-of-the-Art Report on Steel Embedments
The basic philosophy underlying the design of steel embedments may be summarized as follows: (1) If an attachment can be located such that a group of cast-in-place anchors can be used...
Building on Air
Copley Place, a $500 million hotel/retail/office/residential complex, was built on air rights over the Massachusetts Turnpike and an adjacent railroad in Boston. Two hotels occupy land...
Behavior of Metal Structures
This technical symposium illustrates the various aspects of transfer of information from research results to engineering practice. The papers cover historical technical background, current...
Building Trends: The View from Houston
Highligts of the major changes in building design and construction over the past decade are presented from a structural engineer's viewpoint. The areas covered include: (1)...
Record Concrete Box Girder Spans Houston Ship Channel
The Houston Ship Channel Bridge is an American advancement of the cast in place, post-tensioned, segmentally constructed, concrete box girder design. In spite of the complex and unique...
Mechanical Fastening of Structural Wood Members?Design and Research Status
A brief overview is provided of the current mechanical fastening research base as background for a discussion of future research needs and priorities. A summary is presented of the current...
Causes and Preventions of Lamellar Tearing: Engineer's Notebook
Within the past 10 years, a steel cracking problem, lamellar tearing, has arisen after welding of thicker sections and higher-strength steels. A separation underlying a weld joining plate...
Minicomputers in Structural Optimum Design
A problem dealing with the weight optimization of girders without transverse stiffeners is demonstrated. Constraints follow the 1978 AISC Specification. Actual programming is done in BASIC...
Re-decking a Bridge With Precast Concrete
Re-decking a 1627-ft deck girder bridge on the Pennsylvania Turnpike with precast concrete slabs allowed the bridge to remain partially open to traffice during the entire construction...
Vail Pass Highway�Respecter of Mountain Ecology
Environmental constraints to a large degree controlled both the design and construction of a 14-mi segment of Interstate Highway 70 through Vail Pass in Colorado and necessitated adoption...
Parrotts Ferry Bridge: Pioneer in Lightweight, Pumped Concrete
Spanning the Stanislaus River in Northern California, this bridge includes a 640-ft center span that is the world's longest span in lightweight concrete and the longest bridge...
Part Two: Basics in Failure Analysis of Large Structures
Part two of a article, with part one appearing in May, 1980. Part two begins with microscopic examination which includes the use of scanning and transmission electron microscopes. Covers...
Steel Plate Shear Walls Resist Lateral Load, Cut Costs
Two new buildings have a seldom-used stiffening system�� steel plate shear walls. Reasons for using them, rather than reinforced concrete shear walls or steel or concrete rigid frames,...
