Seismic Vulnerability Evaluation of Historical Buildings by Performance Curves, Case Study for Ramsar Museum
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 6, Issue 6
Abstract
The purpose of this paper is to produce a systematic way for structural analysis of unreinforced masonry buildings. Because in analysis of historical masonry we face to lots of problems, such as: the geometry is usually missing, the constitution of the inner core of the structural elements is unknown, a complete mechanical characterization of the materials utilized is hardly possible, the sequence of construction is not documented and the building processes vary substantially from one period to another as well as from one site to another , finite element discretization, knowing mechanical properties of materials and simplification of finite element models. One of the questions researchers face in seismic analysis of historical building is that, how much of demand- capacity ratio can acceptable to assessment level of damage on the basis of linear- elastic analysis? By introducing such a limitation, useful simplification has been done which leads to save expense, time and easy interpretation of results. In this paper, by case study of a historical building of Ramsar museum, first site's seismic demand has been estimated for different hazard levels then the structure has been analyzed finally it has been controlled by suggestive criteria in research. At last it's cleared that limit criteria and introduced performance curves are practical and could be used as a suitable tool to develop planning purposes of researchers who work on analysis of historical buildings.
