Hollo-Bolt

Design guide

1. Define Hollo-bolts in IDEA Statica

• Copy material 8.8 and rename it to Hollo-bolt

• Copy bolt (ex. M16) --> Edit A and As  (Area values from table below)

• Shear plane in tread --> Unchecked

2. Check design resistance values (Lindapter vs IDEA Statica)

3. Manually check the bolt distances 

4. Run 

A an As (Gross cross-section area & Tensile stress area)

Design resistance values (Lindapter vs IDEA Statica)

Shear plane in tread --> Unchecked

Bolt distances for Hollo-bolts

Hollo-Bolt  Resistances

Design resistance = Characteristic resistance / 1.25  (γM3)

Example: M16 (tension design resistance) = 67.4 kN    -->  84.3 / 1.25
