I saw a house with horizontal cracks underneath the beam( at beam and wall joint). Since there are no diagonal cracks that could possibly be due to uneven settlement. I do not think these cracks are due to imposed load since it has occured in upper floor where there are no heavy structures...I am bit confused how did this happen. Plz help me to figure it out.

The horizontal cracks which you have seen beneath the beam are non structural cracks,which generally occur due to temperature differential and generally you can see such cracks in top floor.The width of crack will depend on Quality of materials and workmanship.

Normally this occurs when the thickness of filler material is more than what is required for eg; it must be below 10mm, but masons when they cannot close that small gap with nominal size of brick, they just fill it with mortar and hence due to shrinkage cracks developed.............hope my observation is true to the best of my knowledge Best regards
