Material parameters.

Material	Gravity γ (kN·m^−3)	Elastic modulus E (MPa)	Thickness (m)	Poisson’s ratio v
Columns	27	3.15 × 10^4	/	0.15
Baseplate	25	3.15 × 10^4	1.2	0.15
Middle and upper plate	25	3.00 × 10^4	1.0	0.15
Beam	25	3.15 × 10^4	/	0.15

Note: The constitutive model of the material shown in Table 3 is elastic, and the cross-sectional area of the beam material is 1.0 m², with a moment of inertia of 0.0833 m⁴.
