Özet:
Deformation capacity criteria of structures that are under earthquake effect could be obtained from various world-wide used seismic codes. Eurocode8 (2005), FEMA356 (20009 and Turkish seismic code (2007) are three of seismic code compared in this study. Eurocode8 (2005) which is the basic of this study, recommends calculating deformation capacity of beams, columns, and walls by empirical chord rotation expressions at Part 3 (Assessment and Retrofitting of buildings). Moreover Eurocode8 (2005) proposes that under restrictive conditions the cord rotation demands could be estimated from linear static or linear modal spectrum analysis if important-significant irregularities do not exist. In this study empirical plastic chord wanted to be validated by comparing them with other seismic codes limitations and tried to be observed for different parameters effect on chord rotation demands of simple, regular rectangular column sections.
