The paper shows the approach toward the construction of a very large Pultruded Fibre Reinforced Polymer (PFRP) temporary structure realized to accommodate future restoration work and to cover a historic church stroked and partially collapsed by 2009 L'Aquila earthquake. The aim regards the analysis and evaluation of seismic performance of that structure made by very light and elastic-brittle material, as FRP material, in a moment in which there is a loss of technical recommendation for specific calculation in seismic field, indeed actually some deepening already present in literature allows only static field. The covering structure is an all FRP spatial-reticular with elements made by pultrusion process, connection plates by bag molding process and steel bolts. The PFRP structure covers more than 1050 meters squares surface with 32 meters height and only 100 kN weight. Detail performance of first part of PFRP structure through mode vibrations and involved percentage mass deduced by numerical approach with discussion of employment's perspectives of PFRP material in seismic zones than traditional material are showed. © (2014) Trans Tech Publications, Switzerland.

Abstract
The paper shows the approach toward the construction of a very large Pultruded Fibre Reinforced Polymer (PFRP) temporary structure realized to accommodate future restoration work and to cover a historic church stroked and partially collapsed by 2009 L'Aquila earthquake. The aim regards the analysis and evaluation of seismic performance of that structure made by very light and elastic-brittle material, as FRP material, in a moment in which there is a loss of technical recommendation for specific calculation in seismic field, indeed actually some deepening already present in literature allows only static field. The covering structure is an all FRP spatial-reticular with elements made by pultrusion process, connection plates by bag molding process and steel bolts. The PFRP structure covers more than 1050 meters squares surface with 32 meters height and only 100 kN weight. Detail performance of first part of PFRP structure through mode vibrations and involved percentage mass deduced by numerical approach with discussion of employment's perspectives of PFRP material in seismic zones than traditional material are showed. © (2014) Trans Tech Publications, Switzerland.
