玻璃结构设计通常由拉应力控制。 For the tension stress components, σx, σy, σ1, and σ2, the design ratio is determined with regard to the limit stress. If the limit stress is not exceeded, the ratio is less than or equal to 1, and the stress analysis is satisfied.
The ratio is calculated only for positive (tension) stress values, σx, σy, σ1, and σ2, because the tension stiffness σlimit,d is governing for glass. The table in Figure 01 describes the calculation of the ratios.
For unique or special glass design projects (i.e. glass beams, glass stairs, etc.), additional stresses other than tension may be important for design consideration.
