New seismic behavior model of not reinforced or stacked masonry buildings

Project Details

Description

The response of non-reinforced masonry walls to seismic excitations perpendicular to the plane, responsible for the majority of damages and collapses in this type of structures, is one of the most complex and poorly understood areas of seismic engineering. from the scenarios of earthquake damage in unconfined masonry structures not reinforced, it is observed how some constructions suffer severe pathologies and even collapse, while others do not present any damage. the above is clear evidence of the need to delve into the phenomenology of the problem with models that explain the observed resistance, in order to quantify the incidence of some variables, which previous studies have identified with marked influence on the seismic behavior of this type of buildings. -definition of design, construction and reconstruction requirements of unconfined non-reinforced masonry structures, located in areas of intermediate and high seismic threat. - presentation of an alternative structural system that is technically and economically viable in areas of seismic threat (unconfined mampostery not reinforced or stacked).

Objective

Propose a new analytical model, verified with experimental results, that allows estimating the incidence of configuration and load variables in the resistant acceleration of non-reinforced masonry structures not confined in order to propose new technologies for the analysis and construction of new structures , and the maintenance of the infrastructure built in unconfined non-reinforced masonry, so that the competitiveness and productivity of the companies belonging to the cluster of housing construction is increased, construction costs are reduced, the use of this system in areas with seismic threat, and a lower affectation of natural resources is guaranteed by promoting this type of structures without the need to propose its demolition as the only alternative

Expected results

Development of a methodology to determine the influence of the roof type on mncnr or stacked structures
