Corner padstone

[Josha456]

Hi

I have a beam landing on the corner of a continuous masonry wall, if a corner padstone is used is it reasonable to design the bearing pressure under the padstone as if it was a straight padstone centrally loaded?
the design codes do not consider this case and i am wondering about accounting for the eccentricity?

thanks

I don't think compressive stress can be expected to fan out as it would when situated in a continuous wall. Eccentricity would tend to increase bearing pressure at the corner.

Unless I'm misunderstanding you, for running bond, I've always treated it that way, except if there is a 'joint'.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

The following is excerpt from BS 5628 ..

If the beam is supported on both walls with square bearing area , you may design as if it was a straight padstone centrally loaded and the load would be shared equal by both walls ..

However, ( in most cases , ) the lintel beam extends towards one of the walls. It is assumed that the load is distributed with 45 degr. starting from the both sides of the beam . It will be reasonable to distribute th load acc. to bearing length vs width .
