Study on Mechanical Characteristics of Light-weight Complex Structure Composed of a Membrane and a Beam String Structure
This paper aims at studying a new type of Beam String Structure, in which a membrane is used as finishing material. This paper reports on the mechanical characteristics of this structure,...
Active Control of Axial Forces in Beam String Space Frames
The present work discusses a formulation for active control of axial forces of strings in beam string structures to dynamically and/or statically reduce the responses, and proves both...
Study on Structural Characteristics of Air-Inflated Beam Structures
The purpose of this paper is to clarify the structural characteristics of nonlinear load-carrying behaviors of air-inflated beam structures in their finite deflection range and after wrinkles...
Morphology of Reciprocal Frame Three-Dimensional Grillage Structures
This paper is an introduction to the morphology of structures using the Reciprocal Frame (also known as Mandala Dach in Germany) which is a patented three-dimensional beam grillage structural...
How to Optimize Light-Gage, Cold-Formed Steel Beams
The Illustrative Examples section of the AISI Cold-Formed Steel Design Manual (AISI 1989) demonstrates how to analyze a number of different cold-formed steel sections. This paper applies...
RC Beam-Column Element for Nonlinear Frame Analysis
Recent studies have shown that beam-column finite elements that enforce equilibrium rather than compatibility along the element are better suited for the description of the strength and...
Finite Element Analysis of Shear in RC Girders
Two complementary approaches are presented to model the shear behaviour of reinforced concrete structures. A local one, based on a probabilistic modelling of cracking, accounts for local...
Optimization of Controlled Structures: Using
This paper presents the algorithm for the design of a controlled structure in which the structural and control systems are designed simultaneously. The problem is posed as an optimization...
Computer Analysis of Continuous P/C Highway Bridge Girders with Variable Depth
A computational procedure and associated computer program were developed for the analysis and design of P/C continuous beams with variable depth. Using this program, continuous girders...
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...
Colloidal Fouling of Reverse Osmosis Membranes
Experiments on the fouling of thin film composite and cellulose acetate reverse osmosis membranes by aluminum oxide colloids are reported. Fouling was significant at high ionic strengths,...
Removal of Bromate After Ozonation by Electron Beam Irradiation
Drinking water regulations related to disinfection, disinfectant by-product (DBP) control, DBP precursor removal and contaminated source water pre-treatment will become increasingly stringent...

Questioning Composites
Steel, concrete and timber are, of course, the most commonly used construction materials. Composites, or fiber reinforced plastics, have been used in specialty applications in construction...
The French Composite: A Bridge for Normandy
Aside from its record breaking 856 m span, the most important fact about France's 2,141 m Pont de Normandie�the Normandy Bridge�is that it is being built at all. The bridge...
Design and Uses of Reinforced Shotcrete in Underground Projects in Canada
The first use of steel fibre reinforced shotcrete (SFRS) in Canada was using the wet-mix process in the support of deteriorated ground in 80 year old railway tunnels in the Fraser Canyon,...
Technical Note: STC-40 Shotcrete Adhesion In Situ Tester
It is essential that the shotcrete when reinforcing the rock mass achieves a good adhesive bond to the rock surface. The strength of that bond can be controlled by pull out testing either...
Fire Testing of Shotcrete Samples in a Small Furnace
The fire resistance behaviour of 8 shotcrete samples were investigated in a laboratory furnace applying ISO 834 standard test. Shotcrete was applied on 20 to 30 cm thick granite slabs...
