What is the distance from top of footings to ground floor? Does the wall load extend over the square footings? Have you considered omitting the strip footing, increasing each square footing to, say 2.5m square and relying on the masonry wall to act as a beam, or adding a slim grade beam...

Cutting the slab and excavating for a footing gives you an opportunity to inspect the underlying soil. It is recommended.

If the trusses are made whole, it is more likely that the beam will be supported by the 10 or 11 bottom chords, because the trusses spanning 28' are stiffer than the beam spanning 21'. So the trusses will likely pick up the ceiling load via the beam which is a continuous member spanning only...

Looks good! Pretension through the beam each side of bottom chord is the best solution.

I agree that the existing trusses haves been seriously compromised by cutting the bottom chords to accommodate a 21' long beam. There may be ten or eleven trusses involved as truss spacing is 24 inches. Tension capacity in the bottom chords must be restored by providing tension straps at...

BA - I don't disagree, but who pays for the repair is going to be someone else's battle to sort out. No, it should be sorted out now. The cost of repair includes the cost of engineering which, at the moment, is in some doubt. Preventing morons from cutting structural members without asking...

Determine who was the idiot who cut the members and make them pay for the repair.

Anchor the pipe in the footing. The cost is minimal. Bond between smooth pipe and concrete is not reliable. Reinforcement is deformed, providing good bond with concrete.

Shear deformation is normally ignored. Take the normal cantilever deflection plus theta*Lc where theta is the backspan rotation due to the cantilever moment and Lc is the length of cantilever. Google "Beam Diagrams and Formulas" and you will find several load combinations. The sketch above...

The change to a circular load should require a separate thread. Tacking it onto this thread is confusing. The OP: I have another problem that I am going to tackle and would like your help again. This challenge is to develop beam deflection formulas for a semicircular load applied to a simply...

Of all the things to be concerned about, this must be near the bottom of the list.

Your approach to date has been disingenuous, to say the least.

Column rebars must be grouted twice, once in the beam and again in the upper column. Aligning columns would be difficult.

The concrete strength value will certainly be greater than 8MPa...that would be ridiculously low. I recommend 30MPa as a minimum.

You don't dimension the vertical column, which carries the greatest moment. And you don't show the thickness of the entire shape. But most of all, the building code does not permit plain concrete to be used in a structure such as this. I suggest you omit the jog (saves form work) and...

I believe the bent anchor has merit. It's true there is a lateral force at the bend point, but the lower end has much better tensile resistance than either a L or J anchor.

I can't read that file.

What attached sketch?

I don't want to participate in a discussion about religion; it's not an appropriate topic on an engineering forum. It has such a strong "hold" on some that they will take extreme measures against one another in the belief they are appeasing their god. That is why I don't like that part.
