Stormwater Management Solution
Flash floods are a threat to both existing homes and future development in the Scottsdale, Ariz., area. Engineers studies various alternatives for effective stormwater management an weighed...
New York Gets Wired
With users of New York City DOT's computer-aided drafting and design reaching the limits of the computer system, the department decided to turn the situation to its advantage,...
Removing Metals From Soil
Metals-contaminated soils have been among the most intractable hazardous-waste remediation problems. Conventional mitigation methods of capping, stabilization and landfilling all have...

Development of a High Resolution Spectrometer for Measuring the Near-Earth RFI Environment: The First Auto-Correlator in Space
A detailed description of the near-Earth RFI (radio frequency interference environment in the 0.5 - 16.5 MHz range is required before low frequency arrays can be designed and implemented...
Behavior of Foundations Subjected to Large Ground Movements
The behavior of twelve linear test foundations above an advancing longwall coal mine panel was observed. Three phases of deformation were observed in the centerline foundations: tension,...
Stability of Lift Slab Structure During Construction Stage
The lift slab structures impose stability problems during the construction phase. The process of constructing this type of structure requires placing the masses of the floor slabs at a...
A Generalized Approach to the Local Stability of Stiffened Plates: Part I?Mathematical Formulation
The paper describes a generalized approach for the determination of the buckling stress of stiffened plates under combination of uniform biaxial compression, in-plane bending and shear...
A Generalized Approach to the Local Stability of Stiffened Plates: Part II?Approximate Solution
The paper presents an approximate solution for the prediction of the buckling stress of stiffened plates under combined loadings. A closed form expression is presented for the buckling...
Phoenix Central Library: Reading Room Roof
This paper discusses the design and analysis of the cable truss roof over the fifth floor reading room of the new Phoenix Central Library. Forty pairs of diagonally oriented cable trusses...
Dynamic Analysis of Unstable Structural Systems With Prescribed Velocities
Structural systems that have large inextentional deformation, or in other words, deformation without stain are called 'Unstable Structural Systems.' They include cable structures, membrane...
Dynamic Characteristics of Translational Lattice Domes
The feasibility of using lattice domes of various shapes generated by translating a variety of parametric polygons is illustrated and the dynamic characteristics of these lattices determined....
Discrete Field Stability Analysis of X-Braced Lattices
The three-dimensional X-braced lattice is used as a compression member in structures ranging from the long span roof of buildings to radio and television antennas. In such cases the design...
Ultimate Loading Capacity of Braced Domes
The stability behaviors of a practical latticed dome with 40 metres span are studied in this paper. The geometric and material nonlinear behaviors, as well as the effects of the initial...
The Georgia Dome and Beyond: Achieving Lightweight - Longspan Structures
In the last two decades, the development of longspan roof structures has undergone a quantum leap. The introduction of steel structures, fabric structures, Bucky Fuller's tensegrity structure,...
Effects of Spatial Triangulation on the Behavior of Tensegrity Domes
A number of long span 'tensegrity' dome type structures have recently been realized pursuant to the inventions of R. Buckminster Fuller and David H. Geiger. These structures have demonstrated...
A Practical Design and Construction of Tension Rod Supported Glazing
In designing a glass skin-covered space, for the atrium, entrance hall or other core part of a building complex, the high openness and quality requirements of the space often lead to the...
