Padstone calculator

Structural calculations for padstones

Masonry Input

Beam End Reaction kN (factored) Characteristic strength of masonry N/mm2 Width of beam end bearing mm Length of beam end bearing mm
γm = 3.0
Bearing Factor = 1.25

Masonry Results

Maximum Bearing Stress: 1.08 N/mm2 Actual Bearing Stress: 1.96 N/mm2
 
Padstone Required

Padstone Input

Characteristic strength of Padstone N/mm2 Width of Padstone mm Length of Padstone mm

Padstone Results

Allowable padstone stress: 5.50 N/mm2 Stress under beam end bearing: 1.96 N/mm2 Allowable masonry stress: 1.08 N/mm2 Stress under padstone: 0.93 N/mm2
 
Therefore Masonry Stress OK
Therefore Padstone Stress OK
