Raingage Network Resolution With Spatial Statistics
Spatial and temporal resolution of rainfall are studied using cross-correlation techniques. The cross-correlation coefficient is used in a semi-variogram type analysis to determine the...

Hydraulic Analysis for the Shot Tower Subway Station Beneath the Jones Falls
The objective of the hydraulic analysis is the formulation of a strategy to safely accommodate the construction of the Shot Tower Metro Station beneath the existing Jones Falls. The hydraulic...
A Comparison of Straight and Circular Fibers for Concrete
Two previous studies of concrete reinforced with closed loop fibers are reviewed. Statistical moments of fiber systems are derived, including the expected values of the fiber embedment...
Major Development and Transportation Projects
Public/Private Partnerships
This proceedings for Major Development and Transportation Projects contains papers and discussion summaries from the specialty conference Major Development and Transportation Projects:...
Upgrading Antique Sewers
In a $35 million, four-year program, the Massachusetts Water Resources Authority (MWRA) completely restructed the pumping system serving the sewers under East Boston, Chelsea, Revere and...
Building Moon Bases
It is widely accepted that the U.S. will begin to build a base on the moon at the turn of the century, and much of the design work has already been done. Based on papers presented at Space...
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...
Six Story Tubular Atrium
The author designed an atrium structure with two stair-stepped atriums placed at 45? to the tower 'Figueroa at Wilshire' in Los Angeles, California. This structure...
Buckling Design of Vierendeel Reticular Shells
Double layer reticular shell structures carry very little transverse shear, thus, it may be appropriate to substitute the inter-layer diagonal members with 'space'...
Space Frame Experimental Behavior
Previous tests on double layer grid space frames have shown that, in some cases, significant initial forces exist. In addition, for externally determinate symmetrical tests, there was...
Preliminary Design Considerations for Flat Deployable Structures
Deployable structures are prefabricated frames that can be stored in a compact configuration, and can be easily deployed into a large-span, load-bearing space structure. The interest in...
Unistrut Space Frame Systems and Their Application
A review of the application of latticed structures is presented. The design and construction of space frames is dependent upon the availability of adequate connection systems to realize...
Trends in Development of Steel Space Structures in Japan
Trends in recent development of steel spatial structures in Japan are reviewed. Starting from reviewing early development after the World War II, structural systems such as pyramidal roof,...
Some Examples of Latticed Structures in Spain
Since the middle of the last sixties latticed structures have extensively been used in Spain to cover different large areas as factories, churches, marketplaces, exhibition palaces etc....
Concrete Lunar Bases
Scientific and industrial operations on the moon require suitably shielded structures. Small structures for limited scientific activities may be constructed from structural elements prefabricated...
Rectangular Footing on Nonhomogeneous Elastic Half Space
The problem of a rectangular footing or a strip footing on a nonhomogeneous elastic half space is studied in this paper. The medium is assumed to be isotropic with a variable shear modulus...
Pressure Relief Design Around Pumping Plants
Hydraulic transient protection for an irrigation pipeline pump station can include optimized operating procedures, or design of surge relief equipment such as surge relief valves, and...
Continued Development of the Columbia Basin Project?A Status Report
The Columbia Basin Project is located in central Washington State and encompasses approximately 1 million irrigable acres. Water from the project delivery system was first applied in 1952...
Application of DDDP for Optimal Daily Operation of the Niagara Generating System
This paper describes the application of Discrete Differential Dynamic Programming (DDDP) to determine the optimal operation of Ontario Hydro's Niagara Generating System, on...
