SIMPLIFIED PERFORMANCE-BASED SEISMIC EVALUATION OF BUILDINGS
Simplified, performance-based seismic evaluation of one-story and multistory irregular existing buildings with rigid diaphragms, parallel framing systems, firm and regular foundations is introduced considering impulse responses in addition to damage concentration responses using shear and torsion strength capacity ratios to the corresponding linear shear forces and torsion moments in the x- and y-directions, respectively, in high seismic urban areas. Maximum nonlinear story drift response of each story of buildings can be obtained based on the shear and torsion strength capacity ratio, energy constant and return period concepts considering not only positive slopes but also negative slopes of the skeleton curves in the yielding frames of structures. Allowable or working stress design is not necessary in this method. However, effects of aftershocks are still uncertain. The paper: RECOMMENDATIONS FOR SIMPLIFIED, PERFORMANCE-BASED SEISMIC DESIGN OF BUILDINGS WITH IRREGULARITIES AND DESIGN EXAMPLES presented to 11th US-JAPAN workshop at KOBE, Oct. 17-19, 2006 is much improved in this paper.
