6.1.2　Framing

　

Table 4 - Allowable design stresses for framing

　

where

τ_u is the minimum ultimate shear strength　N/mm²

For the purpose of this standard the minimum ultimate shear strength for aluminium and steel is taken as

τ_u = 0,58 σ_y

　

6.1.3　Core

Core material, sandwich construction

Allowable design shear stress:

　

τ_a = 0,5・τ_u　N/mm²

　

where

τ_u is the minimum ultimate shear strength　N/mm²

　

6.2　Bending stiffness coefficient for FRP construction

The bending stiffness coefficient of individual structural members shall not be greater than (κ₁・span), where κ₁ is defined in Table 5.
