Multi-scale Analysis of the Aging of Composite / Concrete Bonding Subjected to Monotonic and Cyclic Mechanical Loadings

Abstract

The purpose of this work is to establish a rigorous scientific framework focusing on the feasibility and implementation of adhesive connections for offshore wind installations in marine environments. Recently, the development of offshore wind is expected on a commercial scale. The development of technology on commercial projects, however, requires innovative construction, which, in the context of mass production, can reduce production costs and lead times. Also, until now, concrete or steel structures have been used for maritime installations, including oil rigs, floating platforms. A need for new technology has arisen for existing and new offshore structures capable of connecting or replacing secondary structures, elements such as stairs, ramps, gates and windows that meet the needs of security, maintenance, sustainability and economical. In this context, adhesive seals are explored as an alternative and effective solution (Adams 2005). The use of FRP (fiber reinforced polymers) composite materials as structural elements instead of steel guarantees essential advantages such as weight saving, suitability for construction, maintenance, resistance to corrosion and high wear resistance (Baley et al. 2018).
