An analysis of the dynamic response of a fiber-reinforced-polymer (FRP) structure serving as a temporary (weather) shelter for the church of S. Maria Paganica in L'Aquila is presented. The church suffered roof collapse during a magnitude 6.3 earthquake in April, 2009. The structure is a rectilinear space frame constructed from built-up members of pultruded profiles and steel bolted FRP gusset plates. It has a maximum height of 32 m, covers an area of 1050 m2, and weighs (only) 120 kN. Foundations are free-standing blocks of reinforced concrete connected, just above the floor of the church, by steel bars 16 mm in diameter. A finite-element analysis (FEA) is used to determine the seismic response of the main section to the FRP structure. The nonlinear FE responses of the structure subjected to design response spectra (in the ultimate limit state) are presented and evaluated. © 2014 Springer Science+Business Media New York.

Abstract

An analysis of the dynamic response of a fiber-reinforced-polymer (FRP) structure serving as a temporary (weather) shelter for the church of S. Maria Paganica in L'Aquila is presented. The church suffered roof collapse during a magnitude 6.3 earthquake in April, 2009. The structure is a rectilinear space frame constructed from built-up members of pultruded profiles and steel bolted FRP gusset plates. It has a maximum height of 32 m, covers an area of 1050 m2, and weighs (only) 120 kN. Foundations are free-standing blocks of reinforced concrete connected, just above the floor of the church, by steel bars 16 mm in diameter. A finite-element analysis (FEA) is used to determine the seismic response of the main section to the FRP structure. The nonlinear FE responses of the structure subjected to design response spectra (in the ultimate limit state) are presented and evaluated. © 2014 Springer Science+Business Media New York.
