On the modern use of the bòvedas tabicadas
2009
The paper concerns the study of the so-called “bòvedas tabicadas” (i.e. thin vaults constituted by layers of “rasillas” suitably superimposed) based on the results obtained by specific experimental investigations effected on the material of which they are constituted as well as on a vault that is still working. In particular, aim of the present research is the implementation of a first analysis of the structure in its present configuration (often unusable), with the purpose to evaluate the real structure serviceability related to the prescribed intensity of the acting loads, and moreover the execution of a new second analysis of the same structure but suitably reinforced by placing further …

Case Study of the Structural Behavior of a Catalan Bricks Masonry Vault
2015
Catalan vaults are a peculiar type of low thickness vaulted brick masonry structure. Knowledge of load-deflection response and load bearing capacity are important aspects to consider with the aim of preserving these structural members as part of the cultural heritage. In order to investigate these aspects, complete knowledge of the constituent materials and geometry (dimension, thickness, constructive section) is necessary in such a way as to predict the load-deflection response and the effective load-carrying capacity; the latter can be determined utilizing simplified models (limit analysis) or by means of a numerical analysis (finite element method). With this aim, the structural behaviou…

ANALISI TEORICO-SPERIMENTALE DEL COMPORTAMENTO A TAGLIO DI TRAVI PREFABBRICATE RETICOLARI MISTE
2014
An experimental campaign of three-point bending tests on specimens of Hybrid Steel Trussed Concrete Beams (HSTCBs) is presented. The scope of the experiments is the evaluation of the shear strength in the structural typology object of study. Two series of specimens are tested, subjected to positive and negative bending moment, respectively, with the aim to reproduce, in the first case, the condition in the midspan of a beam belonging to a framed structure and, in the second case, the behavior of the beam next to the column where the sign of the bending moment is reversed. The obtained experimental results are interpreted by means of an analytical model for the prediction of the shear resist…
