Reinforcing Roof Truss Frames Under Load
Without altering the roof structure of an industrial boiler plant, a long-span steel truss frame was modified in place to support heavier loads. The owners of an industrial boiler plant...
Building Failures�Construction Related Problems and Solutions
A leadership group of representatives from the fields of structural design, construction, building inspection, the law and insurance agreed that if five changes are made in the way building...
Computer-Aided Load Monitoring System for Nuclear Power Plant Steel Framing Structures
The design of nuclear power plant steel framing structures is a long and involved process. It is often complicated by numerous changes in design loads as a result of additions, deletions...
Computer-Automated Limit-States-Design of Steel Frameworks
The paper concerns the computer-automated synthesis of minimum-weight planar steel frameworks. For any number of applied loading cases, the design of the structure may be constrained by...
Advanced Graphical CAD System for 3D Steel Frames
An innovative, advanced graphical computer-aided design system, called STEEL-3D, is described. The main objective of this program is to provide the engineer with all the tools necessary...
Influence of Connection Behavior on Steel Frame Designs at Factored Loads
This paper illustrates how interactive computer graphics, when interfaced with nonlinear inelastic frame analysis programs, can provide a powerful tool for design of semi-rigid frames...
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...
Underground
The Civil and Mineral Engineering Building at the University of Minnesota in Minneapolis was designed with careful attention to the environment. In the years ahead, this building will...
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...
Compression Rings Support Deep Cut
The plans for building the Cuyahoga Valley Interceptor Lift Station in Cleveland, Ohio, called for 126 ft. (38.4 m) by 105 ft. (32 m) construction, some 80 ft. (24.4 m) below grade. Bracing...
Big New Radio Telescope Array Listens in on Space
The world's most powerful radio telescope is so sensitive that it can detect a small CB rig operating on a distant planet. The Very Large Array (VLA) Radio Telescope Facility...
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...
Building Rehabilitation: The Last Resort
Rehabilitation of buildings often seems initially cheaper than new construction, but the hidden costs of renovation are making many builders prefer new structures. The advantages of new...
