Hello
I am trying to assess the stresses in a pier supporting a beam and attached is a pier.jpg showing the arrangement. The applied loads may be considerable so I need to get the stresses right.
I have a beam that is sitting on a padstone by 215mm with a triangular stress-block applied to the padstone. The action passes through the cg of the stress block. The moment applied to the padstone causes a further stress block in the masonry with the maximum pressure applied to the edge-bricks.
Or. If the beam is sufficiently rigid so as not to curve at the bearing, could I assume a rectangular stress-block and have the load distributed across the padstone which I have shown as a blue line in the stresses.jpg. This then would give a rectangular stress-block in the masonry.
Also, when considering the stresses at mid-height and bottom of the pier, would the eccentricity of the bearing have any effect on the pier.
Regards
