Classification and seismic fragility assessment of confined masonry school buildings

Abstract School buildings being a critical social infrastructure, assessment of their seismic behaviour is utmost importance in ensuring safe schooling facilities locations high seismicity. This study presents two important aspects analysing any existing building stock for behaviour: the development an appropriate taxonomy system and analytical method to conduct fragility assessment. A detailed desk schools’ databases tailored field investigation Guwahati, Assam, situated India’s highest zone, reveal that majority school can be categorised within confined masonry (CM) typology. discusses first, addition World Bank promoted Global Library Infrastructure specific category relating CM as include under study, which are non-engineered with flexible roofs. Identifying density confinement quality connections parameters response these buildings, varying design levels defined relation indicators. Secondly, paper approach carrying out nonlinear static pushover analysis diaphragms elaborates on criteria adopted determining performance drift limits design. Numerical capacity selected index carried using commercial software enables extreme loading analysis. Different failure mechanisms function level identified range three damage states obtained by N2 method. The shows influence both choices indicators intensity measure resulting functions. Given consistency educational results used investment retrofit decision making at regional level.
