POSSIBLE SOLUTIONS BEFORE AND IMMEDIATELY AFTER<br />
EARTHQUAKE<br />
PROF. CLAUDIO MODENA<br />
Structural modelling: Limit analysis<br />
The <strong>possible</strong> failures implemented were selected on the basis of the damage pattern, of the typical<br />
seismic vulnerabilities, of the historical analysis <strong>and</strong> of the comparative evaluation of the numerical<br />
simulation results.<br />
Several failure scenarios were evaluated, <strong>and</strong> corresponding safety factors (α 0 = c) <strong>and</strong> capacity curves<br />
were defined. The different α 0 values of the considered mechanisms give then an indication about the<br />
range of horizontal acceleration values that possibly will bring the onset of the envisaged failure<br />
scenarios.<br />
