Cable Stayed Bridges
Two of these five papers on cable-stayed bridges deal with wind analysis. One develops the theory for motion due to flutter and reaches the conclusion that the vibrations are, in general,...
Cement-Based Materials for Planetary Facilities
The use of concrete and other materials based on a cementitious matrix is evaluated for the construction of planetary base facilities. Consideration is given to the most recent developments...
Composite Construction in Steel and Concrete
Composite steel-concrete systems are used extensively for buildings, bridges, and other civil engineering structures. Research and development related to composite construction are in...
Guide for Design of Steel Transmission Towers
ASCE Manual 52,
Tied Arch Substitute
When the Minnesota DOT decided to build a new bridge to replace St. Paul's historic High Bridge over the Mississippi, a citizen's advisory group insisted that...
Massive Resistance
The recently completed structural reinforcement of the 95 year old landmark Salt Lake City & County building, and its 250 ft high central clocktower, is believed to be the first...
Leakproofing an RCC dam
A roller compacted concrete dam, Stacy Dam in Texas, is described and several methods of preventing leakage are mentioned. Reinforced concrete facings, placed after RCC completion, was...
Weathering Steel: Industry's Stepchild
Improper location and poor detailing are two reasons why some weathering steel bridges are not living up to their early promise. That was the consensus reached during a July 1988 forum...
Stopping the Cracks
It is generally agreed that reinforced concrete in parking garages especially in the deicing salt environment is exposed to unusually hostile service conditions. Deterioration of reinforced...
A Safe Skyscraper For the Seismic City
When completed in late 1989, the 73-story First International World Center will be the tallest office building in Los Angeles. The steel structure of the building was designed to be ductile...
Structure as Architecture
The newest structure at Tampa International Airport in Florida is Airside F, part of an expansion of the first airport designed so that passengers are shuttled via monorail between a main...
Caissons Skirt a Tunnel
Exchange Place Center is a 490 ft, 30 story office tower built directly over the existing transportation hub in Jersey City, N.J., where trains and buses meet the PATH Tubes that carry...
New Horizons in Construction Materials
While civil engineers have, for centuries, built structures and other physical facilities using whatever materials are available to them, there is always the need for stronger, more durable,...
AASHTO Design Concepts
The AASHO Road Test of 1958-60 grew out of a need to quantify the effects of increasingly heavier axle and gross loads and varying wheel load configurations on the performance of this...
Concrete Pavement Rehabilitation Research Findings
A study to improve the procedures for evaluating and rehabilitating concrete pavements was undertaken in 1985. Field and analytical studies have facilitated a new knowledge and understanding...
Preliminary Dynamic Analyses of the Ministry of Agriculture Building
The Ministry of Agriculture building on Avenida San Antonio Abad was originally constructed as a 17 story reinforced concrete structure using a waffle slab system with interior reinforced...
Implications of Structural Characteristics on Failure
Performance of buildings with two common structural types, many of which suffered heavy structural damage or collapse, are analyzed. Conclusions are drawn that no structural type is inadequate,...
R/C Frame Drift for 1985 Mexico Earthquake
This paper contains the results of a parametric study of the displacement response of multi-story reinforced concrete frames. Nonlinear lateral displacement responses were calculated for...
Behavior of Reinforced Concrete Framing Systems
On September 19, 1985, Mexico City was hit by what is believed to have been the most damaging earthquake in its recorded history. In this report, a ground motion recorded in the severely...
Performance of Steel Structures
A description of the various types of steel structures built in Mexico City is made, including comparisons of the older types of steel construction with more modern buildings. Performance...
