Abstract: The design on the
performance-based concept is commonly reposed upon the criterion of storey or
interstorey drift in evaluating the structural performance under seismic
excitation. Nonetheless, there are a few parameters affecting the structural
performance besides drift, such as plastic deformation, dissipation energy,
cyclic fatigue, and natural period of structure. In this paper, evaluation on
the structural performance based on energy concept is interpreted in the value
of Park and Ang damage index. The value of DI equaling to zero indicates no
damage, DI ≥ 1 signifies the total collapse, and 0 ≤ DI ≤ 1 showing the degree
of damage. The analytical method is done on 3 moment-resisting frame concrete
structures under non-linier time history of
Imperial Valley ground acceleration. The objective of this project is to
investigate the degree of structural damage based on the criterion of damage
index so that the structure can be repaired or demolished. The results of
evaluation on damage index of three structures are model-1 structure with DI
0.443, model-2 structure with DI 0.878, model-3 structure with DI 0.325. This
means that model-2 structure with irregular mass system giving the bad
performance.
