Computer Aided Design in Civil Engineering
Increased application of computer aided design and drafting encouraged the organization of the symposium from which this book was derived. The papers presented at the symposium and included...
High Tech Is More Than a Look
Hollow steel section, also known as tubular steel, is being used for its clean dramatic look, its structural efficiency in compression, the economic efficiency of combining structure and...
Structural Trends in New York City Buildings
This story is based on interviews with some leading structural engineers in New York City. It highlights the major structural trends in building design in that city. Case histories of...
The Quiet Revolution in Skyscraper Design
Since the 1960's, there has been a major change in the philosophy for designing high-rise buildings. Up to that time, most buildings were designed to resist wind forces by...
West Coast High-Rise Condo Opts for Ductile Concrete Frame
In the past, the vast majority of high-rise buildings constructed in earthquake prone areas of the West Coast have employed a steel frame. However, recent advances have made it feasible...
Innovations Cut Costs of a Power Plant's Water System
A two-unit (660 MW each) coal-fired power plant in St. Clair, MI, requires 660,000 gallons of water for condenser cooling. A once through cooling system from the St. Clair River (one mile...
Frame Program
A plane frame program for structural analysis that is short to program and easy to understand is presented. Included inl article is a complete print-out of the program with a step-by-step...
Structural Analysis of Light-Frame Subassemblies
Conventional light-frame subassemblies have a long history of good performance. Until recently this performance could not be quantified adequately because of the complex ways in which...
Structural Analysis of Light-Frame Wood Buildings
This paper reviews the information currently available and lacking that is needed for improving design procedures. Some initial attempts at theoretical analysis of entire wood buildings...
Luxury Hotel Features New York's First 8,000-psi Concrete
Designers of New York's $100-million Helmsley Palace Hotel realized significant economies by the use of high-strength concrete to replace structural steel and reduce column...
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,...
Space: A Place to Work
An overview of the nation's space program as space shuttle capability nears reality. The cargo truck aspects of the shuttle will transform our efforts in space. In the near...
Drexel Students Build Space Frame as Senior Project
Drexel University's geodesic tri-span is an open-air monumental structure conceived, designed, fabricated and constructed by a group of senior civil engineering students to...
Gophers Go Underground
A major facility, Williamson Hall, was constructed to be almost entirely below grade on the East Bank Campus of the University of Minnesota. Heating and cooling energy requirements will...
Modern Concrete Structures Survive Romanian Earthquake
On March 4, 1977, 35 buildings collapsed during a severe earthquake (7.2 on the Richter scale) in Bucharest, Romania. Thirty-two of the 35 were older structures, erected before World War...
Exxon's Offshore Platform Nearly Doubles Water-Depth Record
In 1976, Exxon erected near Santa Barbara (Los Angeles metropolitan area) the Hondo platform, in 850 ft of water. This is nearly twice the previous record depth established in the North...
Computer Slashes Time and Cost of Structural Design
An existing computer program for designing floor framing was modified to simplify usage. A preprocessor program was written to reduce the amount and complexity of the input data. A description...
Steel Frame, Precast Floors Meet Impossible Time Constraints
Only 13 months were allotted for expansion of the Captain Cook Hotel in Anchorage, Alaska, which meant that construction would have to continue through the winter months with little down...
La Guardia Airport Parking and Terminal Frontage Structure
One of the world's largest parking structures, at New York City's La Guardia Airport, is of special interest because the structural steel has no fireproofing....
Empire State: Greatest of All Skyscrapers
The Empire State Building! That major name instantly brings to mind Manhattan's intoxicating skyline, a skyline this greatest of all skyscrapers has dominated for 45 years....
