[Retracted] Test of Ultimate Bearing Capacity of Building Concrete Structures in Earthquake Area Based on Virtual Reality

Table 2

Concrete structure parameters.

Concrete structural system	Spatial scale variability	Space expansion flexibility	Facade retrofit flexibility
Framework	Good variability of bay; and depth	Removal of interior walls or partial columns	Flexible
Shear wall structure	Poor bay and depth variability	Difficult to carry out space expansion renovation	Facade windows are restricted
Frame shear structure	Good variability of bay; and depth	Removal of nonload bearing walls or columns	Flexible
