FRCM Composites for Strengthening of Brick Masonry Arches

Abstract

This paper examines the structural behavior of masonry arches strengthened at the intrados with fabric reinforced cementitions matrix (FRCM) composites. Textiles made of poliparafenilenbenzobisoxazole (PBO) and carbon fibers are considered. The experimental results are compared with those obtained on un-strengthened arches and arches strengthened with a carbon fiber reinforced polymer (C-FRP) composite. The tested arches are analyzed with the approach of the limit analysis of the collapse mechanisms.

Unreinforced Masonry Structures‘ Seismic Improvement with F.R.C.M. : the Experience of the Vanvitellian Palazzo Murena of Perugia

“…Aiming at the reinforcement of the arcades the application of F.R.C.M. was envisaged according to a specific designed method, taking into account the architectural value of the mouldings, which refers to the design tips published by the CNR [8] and to the latest analytical and experimental outcomes available in the scientific literature [18,19]. 9600…”

Safety evaluation of masonry arches. A numerical procedure based on the thrust line closest to the geometrical axis

“…For the analysis of arched structures, subject to vertical loads, lateral inertial loads and support movements, targeted investigational tools have been developed [24][25][26][27][28][29][30][31][32][33][34][35][36][37]. Furthermore, effective strengthening strategies, such as those based on composite materials [38][39][40][41][42][43][44][45][46][47], are currently the subject of an extensive research.…”
