Iran is located in a high-risk seismic zone of earthquakes. It has thousands of valuable historic buildings, mostly made of unreinforced masonry, which is quite vulnerable to natural hazards, especially earthquakes. The conservation and seismic upgrading of these buildings is vital for their survival. However, resources are limited and some sort of prioritization is needed in order to alloca...

This paper discusses the results of an experimental study aimed at evaluating influence vertical ground motion component on seismic performance unreinforced brick-masonry buildings. The research was motivated by post-earthquake observations significant structural damage in vicinity fault, where horizontal and motions are often strong synchronized. Vertical accelerations can fluctuate gravity lo...

Walls of corridors and chambers in the Neolithic dolmens of Portugal and Spain were constructed using megalithic slabs or masonry. When constructed with slabs, the slabs were arranged using two very different construction systems, based either on placement of an orthostat or on imbrication of the slabs. Although generally dolmens are described with orthostats, on the Iberian Peninsula are most ...

In this paper a Romanesque masonry church is analysed in order to assess its structural behaviour and its seismic vulnerability with respect to the actual state of conservation. Starting from a specific case study, a contribution to the issue of modelling and analysis of monumental masonry buildings under seismic action is provided. A finite element methodology for the static and dynamic nonlin...
