Ocean Space Encompassed by Oil and Gas Activities
The implications of exploratory and production drilling depth records from 1947 to the present are considered in terms of ocean area involved and coastal management. Technological changes...
Sound Structure
A new concert hall in Dallas, Tex., has the first acoustical design done with the aid of computer simulations that also dictated the shape of the performance space. Those dictates, in...
Optimization: An Emerging Technology
The technology of formal, numerical structural optimization is neither mysterious nor complex. Software programs are now available for use by engineers who do not have detailed knowledge...
The Briny Deep Comes Ashore
Amusement park attractions are not all fun and games. More than 10 years of planning by dozens of firms went into the Living Seas Pavilion at Walt Disney's Epcot Center. The...
Three Automatically Erected Folding Spans
The U. S. Navy has identified three rapidly erected bridges. Each is capable of spanning 400 feet (120 m) with a 70 ton (63 tonne) live load at mid-span. Each will also fold into a 15...
Queensboro Bridge Inspection and Rehabilitation
An in-depth inspection of the Queensboro Bridge revealed deterioration of certain elements on the lower level of the main bridge. These elements include the outer roadway cantilever brackets,...
Serviceability Limit States in Load Space
Deflection and elastic limit state curves are drawn in load space using a nonlinear structural analysis program. Use of load space simplifies computation of point estimates of serviceability...
Stability and Limit Loads of Steel Space Trusses
An investigation of the behavior of cold-formed steel space truss structures, under the interaction of local, member, and overall buckling is described. A Finite Element computer program...
Effect of Connector Spacing on Double Angle Compressive Strength
The 1986 AISC 'Load and Resistance Factor Design (LRFD) Specification for Structural Steel Buildings' includes new rules affecting the design of built-up members...
Microcomputer Assisted Bridge Rating
Before microcomputers can be useful to those officials responsible for rating the approximately 576,000 bridges in this country, software systems must be developed to analyze and rate...
Save the Walls
A rehabilitation job in name only, the 75 year old Army and Navy Club, a landmark located in Washington D.C.'s Golden Triangle, retained only two of its 80 ft high exterior...
Taipei Trade
The appearance of this building is remarkable�so were the cost savings. A design change form rigid shear walls to a ductile frame helped keep construction of Taipei's World...
Terrain Analysis From Space Shuttle Photographs of Tibet
Several Space Shuttle missions obtained false color and large format, high resolution, black and white stereo photography at an approximate scale of 1:800,000. In addition to available...
Engineering Optimization Via Genetic Algorithm
The application of a genetic algorithm (GA) to the optimal design of a ten member, plane truss is considered. Genetic algorithms are search procedures based upon the mechanics of natural...
Computer Aided Structural Analysis
Computer Aided Structural Analysis (CASA) is an interactive computer graphics program designed to solve two dimensional structural analysis problems. CASA is currently used by the Department...
Optimal Collection of Data for Parameter Identification
In this paper, the author attempts to study the optimal spacing of measurements for a structural system modelled by a single-degree-of-freedom oscillator so that the variance of one or...
