DESCRIPTION:Prof. Dr Miguel Castro\, Assistant Professor\, Civil Engineeri
 ng Dept\, Faculty of Engineering\, University of Porto\, Portugal\nThe reu
 se of solid waste is now a subject of critical importance in developed soc
 ieties. Scrap tyres are just one example of solid waste demanding special 
 attention. It is estimated that about 300 million scrap tyres reach their 
 end-of-life each year in the European Union. One of the possible ways of u
 sing recycled rubber from car tyres is through its application in the deve
 lopment of new construction materials. In this seminar\, a research study 
 will be presented that aimed at evaluating the feasibility of using rubber
 ized concrete in composite steel-concrete tubular solutions for seismic re
 sistance. The research comprised an experimental campaign carried out on c
 oncrete-filled steel tubular (CFST) elements made with conventional and ru
 bberized concrete\, subjected to monotonic and cyclic bending conditions. 
 The test results revealed that the hysteretic flexural behaviour of CFSTs 
 is practically insensitive to the type of concrete. The results were then 
 employed on the calibration of 3D detailed FE models developed in ABAQUS. 
 Parametric studies were performed aiming at i) the characterization of the
  effects of multi-axial stress states on the behaviour of concrete and ste
 el materials and at ii) the evaluation of the cross-section slenderness li
 mits prescribed in Eurocode 8 and AISC 341 provisions. The results of thes
 e studies led to the proposal of an improved procedure for the evaluation 
 of the cross-sectional resistance of CFST elements subjected to combined c
 ompression with bending. The presentation will conclude with a comparative
  study of the seismic performance of composite moment-resisting frame buil
 dings made with CFST elements and conventional steel moment frame building
 s. The results obtained indicate that\, in addition to contribute to a mor
 e sustainable environment\, composite lateral loading resisting systems ma
 de with rubberized concrete are an attractive solution for structures loca
 ted in high seismicity regions.\n\nBio : José Miguel Castro is an Assista
 nt Professor at the Civil Engineering Department of the Faculty of Enginee
 ring of the University of Porto. He graduated in civil engineering from th
 e University of Porto in 1994 and concluded an MSc in Structural Steel Des
 ign at Imperial College London in 2000. He obtained a PhD in Civil Enginee
 ring from Imperial College London in 2006. Miguel is an expert in steel an
 d composite structures subjected to earthquake loading conditions and has 
 been actively involved in several national and European research projects.
  He is a full member of Technical Committee 13 on Seismic Design of the Eu
 ropean Convention for Constructional Steelwork (ECCS) and is also a member
  of CEN/TEC250/WG2 that is working towards the development of the new vers
 ion of Eurocode 8\, the European seismic code. His current research intere
 sts are on the development of novel seismic design methodologies for steel
  structures as well as on the collapse and seismic risk assessment of new 
 and existing steel buildings.
