No full textDevelopment of new FRP reinforcement for optimized concrete structures
No full textWith the goal of achieving sustainable design, being able to combine optimized geometries with durable construction materials is a major challenge for Civil Engineering. Recent research at the University of Bath has demonstrated that fibre-reinforced polymers (FRP) can be woven into geometrically appropriate cages for the reinforcement of optimised concrete beams. This innovative construction method enables the replacement of conventional steel with non-corrosive reinforcement that can provide the required strength exactly where needed. The manufacturing of the reinforcement is achieved by means of an automated process based on a filament winding technique. Being extremely lightweight, the wound-FRP (WFRP) cages are well suited to speeding up construction processes, as they can be delivered on site ready to be cast. In this paper, the results of flexural tests on optimised full-scale flexibly formed concrete elements are reported and discussed. Two different case studies are taken in consideration: - A structurally optimized joist supporting a lightweight floor; - A structurally optimized beam with an in-situ casting of a concrete floor. The optimization objective is to obtain the minimal mass of concrete required to achieve the structural capacity design requirements from widely recognized design codes. The experimental results demonstrate the reliability of the technical solution proposed and provide the basis of a new concept for sustainable and durable reinforced concrete structures.</p
Learning structural engineering
No full textTim Ibell, Bath University, shares views on the structural engineering education during the Structural Engineering in the 21st Century academic conference. Students has realized that that good structural design is not about sizing members or following codified rules but is about producing a structural concept which leads to the satisfaction of a set of requirements, including architectural, environmental, building-physics, sustainability and construction issues. The students at the Bath University are expected to describe the structural properties, present case studies, present a SWOT analysis of the material, and analyze its carbon credentials. The students during the first semester of first year are asked to draw a structural cross section, to feel the radiators, to feel the windows, to feel the walls, to consider the construction, to discuss the choice of materials, to discuss the acoustics, to discuss the lighting, and to provide a commentary on possible improvements

No full textTim Di Muzio on 'Sabotage'
No full textIn a series of essays published in 2013 and 2014 on capitaspower.com, political economist Tim Di Muzio explored the concept of ‘sabotage’ as it applies to capitalist power. I recently rediscovered these essays and was so impressed by them that I have reposted them here as a single piece.
About the author: Tim Di Muzio is a researcher at the University of Wollongong. He is the author of numerous books, including Debt as power, Carbon capitalism, and The 1% and the Rest of us
