Minimum thickness of semi-circular skewed masonry arches

The Behaviour of Skewed Masonry Arch Bridges

Surface Interaction Model for Great Thickness Masonry

At present, many of the historic masonry structures in the most important seismic zone of Argentina present damages due to the actions to which they have been subjected. Therefore, it is necessary to study the behavior of walls of ceramic masonry of great thickness. This work presents the comparison between the results obtained from the numerical simulation of ceramic masonry walls subjected to...

On Minimum Circular Arrangement

Motivated by a scheduling problem encountered in multicast environments, we study a vertex labelling problem, called Directed Circular Arrangement (DCA), that requires one to find an embedding of a given weighted directed graph into a discrete circle which would minimize the total weighted arc length. Its decision version is already known to be NP-complete when restricted to sparse weighted dir...

Load Carrying Capacity of Simply Supported Variable Thickness Circular Plates

The calculation of the load carrying capacity of variable thickness circular plates subjected to arbitrary rotational symmetric loading is presented. The analysis considers plate materials that obey either the square or the Tresca yield criterion. By using upper and lower bound theorems of limit analysis, corresponding estimations for the load carrying capacity of the plate are obtained. It is ...

Terrestrial Laser Scanning and Non Parametric Methods in Masonry Arches Inspection

Historical bridges are not only elements of our cultural heritage but also civil engineering structures. They are usually researched with destructive technologies, but their geometry is being more and more used in order to perform structural analysis, and this way it would be possible to make a diagnosis of their state of conservation. Laser scanners collect a great amount of data that allows b...
