Cracks in Concrete Beam 2

[NAFTALI-HAKOHEN]

Hi all

I happened upon a concrete beam, that connects between two large new residential buildings.

Each building around 6 stories.

The beam is only taking its self weight, and has visible cracks at the beam underside, at the connection point to the wall.

Was wondering why the cracks are on the underside (not top of beam at max moment of encastre beam), and is relative movement of the buildings causing the cracks?

Thanks

The crack implies relative settlement of the right side bldg.
It is not a good idea to connect rigidly two bldgs if they do not have common found. , piled founds.. What are the sizes of the bldgs and foundation systems ?



He is like a man building a house, who dug deep and laid the foundation on the rock. And when the flood arose, the stream beat vehemently against that house, and could not shake it, for it was founded on the rock..

That is a fundamentally unsound structural scheme. Connecting beams rigidly at both ends is a recipe for structural distress. What is the function of those beams? They don't seem to be an important part of the buildings. The buildings seem to be unfinished, so now is the time for reconsideration of the beam supports.
