Il porto vecchio di Trieste
No full textL'articolo considera la vocazione portuale di Trieste e ne ripercorre rapidamente la dimensione storica per concentrarsi sul porto austriaco e chiudere sugli sviluppi recenti. Vengono analizzati i vari elementi funzionali del porto e viene fornita documentazione iconografica dei disegni di progetto, delle foto d'epoca , mentre alcune foto tratte da una campagna fotografica cronologicamente vicina all'uscita dell'articolo, documenta lo stato di fatto dell'area portuale, dei suoi edifici e dei suoi elementi funzionali
Innovative Systems for Masonry Infill Walls Based on the Use of Rubber Joints: Combined in-Plane / Out-of-Plane Tests
No full textWithin the INSYSME Project, funded under the 7th Framework Program by the Com- mission of the European Communities and aimed at developing innovative systems for masonry enclo- sure walls, the University of Padova and ANDIL (Italian Association of Clay Bricks and Roofing Tiles Producers) proposed a construction system named DRES (Damage Reduction Enclosure System). The system is made of a single-leaf clay masonry wall, with three horizontal deformable joints within the clay unit rows, to be employed in RC frame buildings in regions prone to medium/high intensity earthquakes. To understand the behaviour of this system, an experimental campaign on four real-scale, one-bay, one- storey RC frames infilled with both partial and full enclosure walls, was performed. The tests combine cyclic in-plane and monotonic out-of-plane loading of the specimen. Two variants of the DRES system and a reference plain masonry enclosure were first tested in the in-plane direction and then in the out-of- plane direction. An additional specimen infilled with two partial enclosures, one built with DRES and one with plain masonry, was first tested in the out-of-plane direction and then, after removal of damaged walls from the bare frame, tested in the in-plane direction. An analysis, in terms of strength, ductility parameters and damage, of the in-plane and the out-of-plane test results is carried out

The INSYSME project: Innovative construction systems for earthquake resistant masonry infill walls
No full textAt the end of 2013 the Commission of the European Communities has funded a research project for the benefit of Associations of Small and Medium Enterprises (SME-AGs), aimed at developing innovative systems for masonry enclosures. The project mainly deals with external partition systems for reinforced concrete framed buildings, i.e. infill walls. The project involves sixteen partners from seven European countries, among which there are seven universities and research centres, five industrial associations and four small and medium enterprises. In the present contribution, an overview of the main objectives and steps of the project is given, together with a general summary of the various construction systems developed by the project partners

In-plane cyclic behaviour of thin joint masonry walls
No full textNew technologies for the construction of reinforced and unreinforced masonry buildings, based on the production of new blocks, are being employed and developed and are recognized by the modern generation of codes. In particular, a technique based on the use of clay blocks with small dimensional tolerance in unit height, i.e. machine flat bed faces, for the use with special mortars for thin layer
joints, has been introduced only recently in most of the European countries. This construction technique allows simple and fast assemblage and enhances the acoustic and thermal insulation of the masonry walls.
As a consequence of the introduction of this system for the construction of masonry buildings also in earthquake prone countries, it is necessary to assess its behaviour under seismic actions. In this framework, an extensive experimental program was carried out at the University of Padua, in order to characterize the mechanical behaviour of the new construction system, also under combined in-plane vertical
and horizontal cyclic loading. The system was studied in comparison with other typologies of masonry walls currently adopted in the practice, characterized by different configurations of head and bed joints.
The test set-up for the execution of shear compression tests was created on purpose for the research, after studying the most appropriate test configurations to reproduce the behaviour of shear walls. All the data collected from the experimental activity were used to assess some analytical models available for the prediction of the ultimate capacity of masonry walls under in-plane uniaxial compression and
shear compression loading. A new formulation for the evaluation of the tensile strength of masonry was proposed and assessed against experimental data. The cyclic behaviour of the specimens was also modelled and this allowed carrying out non-linear dynamic analysis for the evaluation of the reduction of the elastic response of the masonry walls due to their hysteretic behaviour. The results obtained can be used as data-base and input for standardization purposes
