Replacing an Urban Foundation
Baltimore's new subway extension will pass close to a 6-story reinforced concrete building near the Inner Harbor. Its timber piling foundation was threatened by the dewatering...
Structures Congress Abstracts 1990
Abstract only. The following themes are included: Rehabilitation and future challenges, Bridges, Earthquake engineering, Dynamic loads on structures, Metals and composite construction,...
A Hard Look at Concrete
Concrete has been looked upon as something fixed and unchanging, a generic, nondescript mass, But it demands specific engineering attention. Because many existing concrete studies are...
A Seawall for Sea Mammals
With glass walls only 75 ft from Lake Michigan, an aquarium addition demanded solid seawall protection. Yes, in a strange twist of logic, the first step in creating a whale habitat for...
Building in Reservoirs
The Croton Supply System, one of the three major water supply systems for New York City, is undergoing extensive rehabilitation. In an innovative use of space, some of the new construction...
New Piers for an Old Bridge
Placing new piers under an old superstructure has saved the architecture of the historic Ashley River Bridge in Charleston, S.C. In July 1987, an inspection indicated deterioration and...
Rebuilding Philadelphia's El
In reconstructing an urban transit system, the challenge in Philadelphia was to do it without disrupting peak hour commuter traffic or disturbing activities on the street and sidewalks...
High Tech on Campus
Hannan Hall, the new laboratory building at The Catholic University of America, has a structure entirely made up of precast concrete panels and 24 in. deep double tees. The loadbearing...
Changes in Tubular Design Codes
This paper summarizes a number of changes in design provisions for tubular structures that have recently been adopted. These are the result of a number of research advances concerning...
Brace Behavior in a Structural Steel Seismic Retrofitting Scheme
A two thirds scale non-ductile reinforced concrete frame strengthened by an external structural steel bracing scheme was constructed and tested in the laboratory. The frame was subjected...
Manipulation of Shell and Fabric Structure Form
Fabric structures and concrete shells are readily compared because of their curving shapes and the apparent structural derivation of their forms. Every fabric structure includes compression...
An Optimal Design of Steel Pipe Pile Foundation
This paper presents an optimal design method for the steel pipe pile foundation of bridge pier using a nonlinear programming. It is firstly assumed that an imaginary wall model behaves...
Automated Design of Reinforced Concrete Components
This paper presents strategies for automating the design of reinforcement in two types of concrete components, namely T-beams and circular columns. These strategies may serve as examples...
Optimal Design of Tall RC Tube Buildings
The analysis and design of reinforced concrete framed tube buildings is formulated as a nonlinear optimization problem and solved using modern design optimization software. The influence...
Polypropylene FRC In Steel Deck Composite Slabs
Engineers, testing laboratories, universities and metal deck manufacturers have studied polypropylene fiber reinforced concrete (FRC) and compared the results with similar slabs reinforced...
Cracking Behavior Comparisons Between Normal and Fiber-Concretes
A comparative study of the cracking behavior of plain- and polypropylene fiber concrete was performed. Both high- and low-strength concretes were studied. Maximum and average crack widths...
High Strength Concrete: Proportioning, Behavior and Applications
Generally, concrete with a cylinder compressive strength higher than 6000 psi (41.4 MPa) is designated as high strength concrete. High strengths are achieved using stronger coarse aggregates,...
Sulfur Polymer Concrete for Special-Purpose Applications
Special-purpose sulfur concrete construction materials, based on sulfur polymer cement (SPC) and mineral aggregate, have been developed by the U.S. Bureau of Mines as part of a program...
Natural Aggregates in Structural Lightweight Concrete
Pumice and scoria have been used in structural concrete since the days of the Roman Empire. Records for the past five decades show minimal use of these materials in structural concrete...
Polymer Concretes
Polymer Concrete (PC) is prepared by using polymeric materials to bond inert aggregates in a fashion similar to that of Portland Cement in the preparation of Portland Cement Concrete (PCC)....
