A study of CFRP composites effects in seismic retrofitting of concrete connections using ABAQUS software
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 6, Issue 2
Abstract
It is for more than a decade that the category of improvement and quality enhancement of structural engineering infrastructures is considered as one of the most important issues. Devastation and annihilation of pillars, beams, connections and etc. are mainly attributed to aging of structure, harmful and destructive environmental factors, poor design or implementation of configurations, poor maintenance or incidents such as earthquakes. Meanwhile, using carbon-fibre-reinforced polymer composite materials (CFRP) as a practical solution is increasingly getting developed. Although formation of connections is one of the gravest factors affecting the behaviour of reinforced concrete, it is less paid attention and connections are usually brittle from this point. Thus, reinforcement of connections is a significant issue in civil engineering. In this article behaviour and deformation of applied beams in armed concrete which are reinforced with CFRP sheets is investigated. Designing procedure to determine the structures resistance is based on rigidity assessment of connection zone between carbon fibres and concrete. For this purpose the reinforced connection with CFRP sheets simulated by means of ABAQUS finite element software and an improvement in behaviour of the connection in terms of load capacity increase was observed.
