It is a continuous corbel that supports hollow core slabs. Reinforcement is stretched as height is increased. Sketch is on above link.

Continuous RC nib 150mm wide is supporting hollow core slabs. The design is passing for nib height 200mm and given rebar and ultimate loads. In order to make work easier the contractor increased the nib height to 400mm, to make the bottom level of the nib equal to bottom level of the beam. Even...

As written above, that is for intersecting walls that depend on each other for lateral support.

You can solve it with RC beams along the perimeter (on top of the walls), so area 5 will be clear without tension ties.

In my area (one European country) I can get Grade 500 only. Grade 400 is not produced by steel factory. So that is also something to consider. But for pricing of building with all finishes, the cost difference you are asking will probably be negligible.

This detail is used often in the Middle East with sand soil. The beam is usually named tie beam, and block below it used to contain sand below slab on grade since there are differences between outside and inside levels (usually up to 350 mm). In that case, only 3 layers of 200mm solid concrete...

Dear all During Tender process Contractor provided discount on overall amount of works in BoQ. In BOq summary contingency is provided 9%. My question is: For new unit rates paid according to detailed breakdown submitted (market prices), should we apply discount given to overall sum in Contract...

There are no piles. These photos are showing only small pads as temporary support: http://www.universityclubtower.com/progress/photo_gallery/2005_1.cfm

btw this is mat foundation, not pile cap...

@ash60 "How would I do this for the sewer lines? They will be gravity fed. " For story below pipes, sump pit with pump can be used.

Thank u all for replies. In this case I am just checking the design of this bracket. If I did the design from the start I would put top & bottom flange or use a tube section. This design is made by our subcontractor for window cleaning system. The fact is that in their design documents they...

In attachment there is picture in jpeg. Main problem I have is section classification and determining ultimate resistance with respect to buckling. So in general, question is how to calculate ultimate moment resistance for plate with moment acting around major axis. If it is I or tube section...

I need some advice regarding design of bracket main plate. I need some guidance how to check this plate for moment resistance around major axis with respect to buckling (BS EC3 preferred). I was reading several sources but I am not sure in this. Example showing something similar will be helpful...

We have to follow the specs, and supplier is delivering ready mix below 90F. Even air temperature is above 100F.

Yes, as said above, check with ready mix suppliers, they already know how to deal with it. I am working in Middle East, temperatures are extreme, but adding ice to mixture solves the problem.

Hi... If we have 10 floor building with in-situ post-tension slabs with bonding tendons. I am wondering about typical schedule of construction for these floors. I am clear for steps in case of one slab, but I am not sure about passing to the next floor. Could we do concreting of the 2nd floor...

ETABS calculations are correct. But as engineer you have to understand the nature of problem. It persists in all programs. Read in the papers about using construction cases in ETABS.
