Abstract

Trussed wooden beams as well as trussed wooden arches are common typologies covering long span structures of old monuments. The resulting roof shapes are either linear saddle roofs or domes with planar different geometries. Both the cases present common material and structural features, which can influence the static capacity and deformability of structures under sustained dead loads. Eccessive midspann deflection like eccessive deformation of the key or the reins of the arch are quite common pathological aspects shown by wooden monumental roofs. Structural analysis by numerical elastic procedures disregarding non linear behavior of particular sections like joints, generally show non realistic low stress range, even for the most critical load combinations, and insensitive def
