Design of FRP structures in seismic zone

The use of FRP (Fibre Reinforced Polymer) material in the structural engineering field is by now current practice and supported by theoretical studies as well as many applications and constructions.

FRP material is widely accepted in the strengthening of existing structures (made by reinforced concrete, steel, wood and masonry) but not yet commonly used for new buildings even if some recent all-FRP constructions, in particular built with FRP elements made by pultrusion process, are very promising.

The study of the structural behavior of pultruded FRP members, especially in the case of static loads, has been widely developed. Instead, for what concerns the dynamic response, very few experimental and analytical research projects have been proposed. The issue is particularly interesting because of the mechanical characteristics of pultruded FRP material. The dynamic properties of pultruded FRP material are characterized by high periods of vibration, low frequency and a spontaneous dissipative capacity of the dynamic actions due to its low density.

Currently there are no available guidance for the seismic design for structures with pultruded FRP elements.
The aim of this manual, made together with the IUAV Univerisity of Venice, is to address the issues related to the design of pultruded FRP structures subjected to static and dynamic loading.
