Abstract

Prefabricated GFRP continuum/skeletal structural units are utilised in modular construction of a stressed skin double layer roof system. An experimental scaled model of the roof structure was manufactured in perspex and tested, the results of the experimental investigation validated a numerical model of the roof which in turn was employed in a parameter study of a full-scale GFRP roof structure by application of nonlinear load-deflection finite element analysis. The parameter study confirmed that the governing design factors were the deflections of the structure and/or the buckling of the members. Recommendations are made to economically maximise the stiffness and ultimate load capacity of such structures.
