Combination modes of optimal coefficients.

Mode	α	β	γ	Objective of optimization
1	1	0	0	Considering storey-drift angle only, namely, security
2	0.7	0.1	0.2	Taking storey-drift angle as the main factor, acceleration, and storey displacement as additive factors.
3	0.5	0.3	0.2	Considering the weight of storey-drift angle as half of the importance
4	0.1	0.7	0.2	Considering acceleration as the main factor
5	0	1	0	Considering acceleration only, namely, amenity
6	0.5	0.5	0	Considering only storey drift to reflect deformation of the structure
