Abstract:

It is now widely recognized that the conventional construction practices need significant improvements to be able to deliver sustainable urban development. Recent research has shown that the environmental impact and carbon footprint of structures can be significantly reduced through the use of i) more ecologically advantageous construction materials and ii) better designed structural systems. This talk will focus on one of the most promising of these structural systems, the so-called concrete-filled fiber reinforced polymer (FRP) tube system, where the concrete is filled into a prefabricated FRP tube to form a composite member that maximizes the advantages offered by both materials. The behavior of these composite members under different loading conditions will be presented. The development of next-generation high-performance, low-impact structural systems incorporating i) green composite tubes manufactured with natural or recycled plastic fibers and bio-based resins and ii) eco-efficient, waste-based concretes developed using recycled aggregate concrete and geopolymer technologies will also be discussed.
