Assembly and Erection
This chapter is intended to provide recommendations on transporting, handling, assembling, and erecting fiber-reinforced polymer (FRP) poles. An important consideration is that FRP poles...

Metal Building Systems: A New Look
The use of metal building systems in low-rise, non-residential construction under 150,000 square feet has grown from less than 50 percent in 1986 to almost 70 percent today. Such systems...

Innovative Design of Steel Gable Frames
Common wisdom holds that conventionally designed gable frames fabricated from rolled sections cannot compete with metal building system frames fabricated from plate and bar stock, from...

Metal Truss Plates: Less than Full-Depth Penetration and Shear Buckling
This paper presents the results of two experimental studies on metal truss plates which are used to join members of wood trusses. The first study investigated the effect that less than...

Diaphragm Action of Cladding in Low-Rise Metal Buildings
An investigation of the contribution of cladding to the lateral stiffness of a metal building is presented in this paper. The diaphragm action of the cladding tends to redistribute the...

Solar Stretch
Extrapolating from structural work with textile or metal membrane roofs to cover silos, assembly halls and sports stadia, Schlaich, Bergermann and Partners, a structural engineering firm...

Chelating Composite Membrane: Its Application in Selective Heavy-Metal Solid-Phase Separation
Selective removal of small amounts of heavy metals from the background of large amounts of innocuous sludge or slurry is a challenging separation problem. Conventional fixed-bed sorption...

Heavy Metal Removal Using Peat/Wetland Treatment
The purpose of this paper is to present an overview of the mechanisms and application of a peat/wetland treatment system for heavy metal removal from wastewater. The mechanisms involved...

Activated Carbon as a Catalyst for Polymerization of Phenolic Compounds
Previous studies by the principal investigator showed that the increase in the adsorptive capacity of activated carbon for phenolic compounds can be attributed to polymerization (oxidative...

Stability Analysis of Rayleigh-Benard Convection in the Presence of Side Walls
The onset of laminar axisymmetric Rayleigh-Benard convection is investigated for a low-Prandtl number liquid metal in a cylindrical container, in the presence of a vertical temperature...

Heavy Metals Contamination and its Implication in the Development of the Estuarine Zone of the Southern China
During the pat decade, the economic growth of the estuarine region of the Southern China has been astonishingly rapid. One of the major concerns has been the water pollution problem because...

Heavy Metal Accumulation in Subsurface, Estuarine Sediments and Inferences for Anthropogenic Enrichment: N.W. Florida Coast
In an attempt to quantify the degree of contamination and the thickness of the contaminated subsurface sedimentary wedge, approximately 100 samples were extracted from the cores and subjected...

Studies of Contaminants in Arctic Marine Mammals
Attention has been directed over the last few years to determining the baseline levels of anthropogenic contaminants in Arctic marine mammals. Because of their subsistence value to local...

Heavy Metal Pollution of Santa Catarina Island, Brazil
On Santa Catarina Island, Brazil, mangrove ecosystems although considered by present legislation as 'Areas of Permanent Preservation', have been undergoing progressive elimination for...

Modeling the Fate and Transport of Toxic Heavy Metals in South San Francisco Bay
A two-dimensional vertically-averaged finite element model for the fate and transport of cohesive sediments and associated toxic heavy metals was utilized to predict the spatial and temporal...

Damage Dependent Micromechanics in Metal Matrix Composites
A computational approach is used herein to model the effects of processing induced thermal residual stresses on radial, hoop, and shear stresses at the fiber/matrix interface in a continuous...

Micromechanical Characterization of Damage-Plasticity in Metal Matrix Composites
A micromechanical theory of damage mechanics and plasticity is proposed for fiber-reinforced metal matrix composites. The composite system is assumed to consist of elastic, continuous...

Fracture Toughness of DMMC
The fracture toughness of discontinuous metal matrix composites (DMMC) is always less than the fracture toughness of the matrix, in the same heat treatment or annealed condition. If a...

Optimum Design of Laminated Metal Matrix Composites
With the increased demand for high-strength, lightweight materials that function successfully in high temperature environments, the effective development of metal matrix composites has...

Observations of Microcracking and Pore Collapse in Limestone Using Liquid Metal Porosimetry
A technique has been developed to preserve and observe the microstructure of rock or other porous material, as they exist under stresses, using liquid metal porosimetry. Cylindrical specimens...
