    Abstract: The City Hall of Mirandola was stricken and damaged by Emilia-Romagna earthquake sequence of May 2012. This paper presents the procedure for the structural monitoring control of a masonry historic building that presents a serious damage pattern. Structural monitoring was carried out with transducers installed to control the serious cracks that regards the main volumes of the building. The global structural health monitoring was useful to define the actual condition of the dynamic behavior of the damaged construction that are subjected to different mechanism. Ground penetrating radar allows to detect the depth of the cracks and the condition of the masonry. These researches are useful also for the structural future rehabilitation and to define the possible changes in the structural behavior.

    Knowledge of the Construction Technique of the Multiple Leaf Masonry Façades of Palazzo Ducale in Venice with ND and MD Tests
    Trans Tech Publications, Ltd. ; 2014

    In: Advanced Materials Research, Trans Tech Publications, Ltd., Vol. 919-921 ( 2014-4), p. 318-324
    Abstract: This paper presents a first program of non-destructive tests carried out on two medieval façades and inside the main rooms of Palazzo Ducale in Venice, i.e. the room of Maggior Consiglio and the room of Scrutinio. A probably multiple leaf load-bearing brick masonry and an external cladding of polychrome stones compose these façades under investigation. The aim of the tests concern the improvement of knowledge about the construction technique and the mechanical features of these important historical facades. The program was set up after a preliminary historic investigation. Non-destructive and minor-destructive investigations (i.e. pattern surveys, endoscopic tests and georadar test) on the inner sides of the two walls of the area under examination were carried out for the analytical determination of the construction technique and structural characteristics, not clearly inferable from the literature.Due to the complexity of the structure and the transformations undergone in seven hundred years of life, and to the very limited investigable areas of the internal surface, the results of investigations cannot be extended to the entire structure. Nevertheless, these tests provide valuable clues to give a correct interpretation of the construction technique and to contribute to identify the possible mechanical properties, which provide knowledge about the health state of the building.

    Abstract: The paper shows the results of monitoring activities to check the structural response and the level of damage of two historic monument of LAquila: San Pietro di Coppito and Santa Maria Paganica, that were damaged by the main earthquake of April 2009. The diagnostics operation was planned and carried out in situ and in laboratory to verify the integrity of the residual stiffness of the structures and to define the mechanical parameters of the material. The mechanical characterization of materials was carried out through destructive tests on samples, taken directly on site, and micro-destructive tests through single and double flat jacks. To give a first qualitative assessment of overall was used sonic test (non-destructive test) on the main macro-structure. The global structural health monitoring (SHM) was carried out through ambient vibrations to define the real dynamic behavior in serviceability state and to calculate - via a modal identification of output-only systems-the dynamic parameters (mode of vibration, frequencies, displacements and damping ratios). The aim of this research is to prove the reliability of different diagnostic methodologies, the real extent of global and local damage and the extent of the residual stiffness of the macro elements of the structures (façade, tower, walls of nave, transept) that are subjected to different mechanism of failure.

    Abstract: The present work proposes and analyses the solution for seismic behaviour of GFRP (Glass Fiber Reinforced Polymers) applications to evaluate the performances respect to dynamic actions considering the global effect on historical structures. The good strength-self-weight relationship defines the GFRP pultruded profile as an efficacious and innovative solution for structural rehabilitation of historical buildings. The composite material with polymeric matrix, FRP (Fiber Reinforced Polymers), is widely used in civil engineering as sheets, bars and strips. Recently a new technology was adopted to improve the structural response with limited increment of dead load with reversible and independent solution.

    Abstract: This investigation presents some evaluation based on the experimental and numerical results obtained on the compression bearing capacity of new columns prototype made by FRP (Fibre Reinforced Polymer) material and concrete. In detail that is the junction due to the assembly between hollow FRP profiles made by pultrusion process with glass fibres and thermosetting matrix vinylestere, and very light concrete casting inside. To better understand the eventually influence related to the hollow shape employed, the study consider both the case of circular and square profile. Due to the novel of the research, a not negligible part of the research is dedicated to test previous the separate material, that is the plane concrete and the hollow GFRP profile, and then the prototype (concrete+GFRP) also considering two different way of load application. Particularly we applied in the first case the load to only the core of the sample, on the plane concrete, and then to the total cross section. This choice allows to evaluate the role and the influence of the bond strength along the length of each sample.

    Abstract: A CGF Panel (Concrete Glulam Framed Panel) is a concrete panel with a glued laminated timber frame. The experimentation on this new construction system at LabSCo (Laboratory of Strength of Materials) of IUAV University of Venice, inspired a wide research on buildings made of this construction system investigating in different aspect of building behaviour: particularly about mechanical property of the materials, mechanical of the system and building physics. This paper presents the results of quasi-static in-plane tests on single panel and configurations of some different panels. The tests in the laboratory are used for measuring the in-plane strength and stiffness of individual panels and wall sections consist of some panels in order to verify and measure the behavior of the connections between the various parts of the single panel and the connection between the panels. Thanks to the results obtained it was possible carry out the FE model to calibrate the characteristics in relation to experimental data. Finally, in order to compare this constructive system with the well known X-lam systems, on the basis of the calibration of the models we were able to set up a comparable FE model with those of the X-lam wall described in the publication: "Quasi-Static and Pseudo-Dynamic Tests on XLAM Walls and Buildings " inherent in the SOFIE project coordinated by the CNR-IVALSA (Italian National Research Council - Trees and Timber Institute)

    Abstract: In this work the behavior of masonry arches, without reinforcement and with partial reinforcement, is investigated by means of three different numerical models. The first one is a Discrete Element model based on rigid blocks, and elastic-plastic interfaces; the second one is a standard heterogeneous Finite Element Model, which is adopted for a detailed micro-modelling of arch voussoirs, joints, and reinforcements. The third model is analytic-numerical, and it is adopted for validating the other numerical results. The aim of the work is the comparison and validation of the numerical Finite and Discrete Element models for the correct simulation of masonry arch behavior, together with the evaluation of the effectiveness of these models in simulating the behavior of the partially reinforced arch.

    Abstract: During the seismic event of May 2012 in the Emilia-Romagna Region (Italy), several cultural heritage structures collapsed or were severely damaged. This paper gives a description of the damage/collapse mechanisms observed on some of these buildings. The Church of Gesù, the City Hall and the tower of the Cathedral in Mirandola (MO) were analyzed. In particular, this article focuses on the behavior analysis of a church, a palace and a bell-tower, mainly masonry construction, that are the most widespread types of protected monuments proposed in the Italian code as simplified models for the verifications on the entire cultural heritage of a prior assessment of the seismic risk. The survey permitted to detect the most significant damage, mainly related to the cracks of the masonry and to understand the different collapse mechanisms.

    Abstract: This work shows the results of monitoring of Santa Maria del Suffragio (Anime Sante) church, L’Aquila, Italy. The historical building was stricken and damaged by mainshock of April 6, 2009; the dome is the structural element that has been seriously hit by seismic event. The ambient response analysis of global structure and dome element enable to improve the FE model by model updating methodology using modal data. The identification techniques furnish useful information concerning the structural and mechanical properties of dome’s structure, these parameters are needed to evaluate the appropriate design of rebuilding and structural rehabilitation of dome. The geometric configuration and the self-weight of lantern induce to an independent dynamic response of macro-element against the behaviour of dome generating the first mechanism of collapse and the failure of dome shape. Different retrofitting configurations for the dome have been proposed in this paper.
