Seismic Performance Assessment of a Multistorey Building Designed with an Alternative Capacity Design Approach

Table 4

Evaluation of the influence of the soil class on the seismic performance of the building. Comparison between the two design approaches (single-q and variable-q) for the different soil classes considered.

Performance measure	Design approach	B soil class	C soil class	D soil class
Number of fatalities	Single-q	0.17	0.251	1.41
	Variable-q	0.099	0.144	0.848
	Relative difference	+41.76%	+42.63%	+39.86%
Number of injured people	Single-q	0.44	0.63	3.41
	Variable-q	0.30	0.35	2.43
	Relative difference	+31.82%	+44.20%	+28.74%
Total repair cost ($)	Single-q	44 755	74 632	397 712
	Variable-q	36 816	62 973	342 561
	Relative difference	+17.74%	+15.62%	+13.87%
Total repair time (days)	Single-q	3.39	5.48	29.68
	Variable-q	2.83	4.59	25.84
	Relative difference	+16.52%	+16.24%	+12.94%
