We are building new, and the carpenter says that this joint should hold for the load on the upper floor. The underside of the beams has no tensile strength, and all joints have been added to the same side. I sent the pictures to the engineer who designed the floor structure, and he approves the joint as follows, and the construction supervisor says that the responsibility lies with the engineer and he can't do more. Does this method really hold??
"Hello Hassan! The joints on the beams are included in the dimensioning of the floor joists and are approved, so it looks good. Best regards"
