Historical masonry constructions are typically complex, and there is a lack of knowledge concerning their structural behavior, particularly as far as their seismic response is concerned. Generally, they are more massive than today’s structures, they usually carry loads primarily in compression and they are not conceived to withstand seismic actions. Successful modeling for ancient masonries is a prerequisite for a reliable earthquake resistant design or assessment.
The seismic behavior of old masonry structures is however particularly difficult to be examined, because it depends on many factors such as material properties, geometry, stiffness of the floors (diaphragm effect) and the connection between orthogonal walls. In this framework, during the last decades the scientific community has developed different approaches, to achieve a consistent description of historical masonry constructions. An overview of methods for the modeling of old masonries, starting from simple traditional to modern methods suitable for use in computer programs, is requested.
Main characteristics of historical masonry structures, as well as principal features of methods for their analysis, such as dynamic analytical methods, limit state methods, finite element methods, and discrete element methods, are favored. A review of the application of individual methods about the required level of accuracy, the quantity of input data, and calculation time, are also demanded.
Topics to be covered, but not limited to, are:
• Advanced numerical models
• Seismic assessment of historical constructions
• Repairing and retrofitting interventions
• New strategies for the preservation of heritage structures (SHM, damage detection, …)
• Nonlinear static and dynamic analysis
• Incremental Dynamic Analysis applied to historical structures
• Constitutive models for masonry materials
• Homogenization techniques
• Multi-scale analysis
