SEISMIC RELIABILITY ANALYSIS FOR VULNERABILITY ASSESSMENT AND PERFORMANCE-BASED DESIGN OF IRREGULAR BUILDINGS

an overview is presented about the influence of different types of structural irregularities on the nonlinear dynamic response and on the reliability functions of multi-story buildings subjected to seismic excitations of different intensities . attention is focused on the following types or irregularities : a vertically irregular systems characterized by significant variations of the floor masses , the storystrength and stiffness properties and the safety factors with respect to story shear associated with linear seismic response , b)in-plan irregular systems characterized by sinificant eccentricities of the story shear-forces determined by linear dynamic response analysis with respect to the corresponding centres of lateral strength and stiffness.
