Question

beam openings for tower


This is for 35 story tower. The beams at level 3 and 4 are 1.2 meters deep and 6 meter long. two rectangular openings .7m x.7m (top and bottem of opening is .25meters each) were introduced in the middle and 1.5 meter from side of beam to cross the MEP ducting requirements. 2-25 dia additional bars were introduced on T/B and both sides and diognaly by the contractor.

Only 9 stories are built till now.

As a thumb rure can some body comment if theses are safe or some thing to be done at this stage.

Thanks an regards

You need a structural engineer. If questions like this are coming up on a 35 story building, you are in the wrong place. This is a DIY homeowner site................... and good luck with the remaining 26 stories.

sandeep,

When you finish that 35 story building could you do me a favor and post a sign on the door that says "Warning, This building was built using structural advice from unknown persons on the Internet."

I can't believe you're actually building without an Engineer. Call the Engineer that designed your project for his approval.

In one of your other posts you said you were a Structural Engineer. So are you or aren't you a structural engineer?

Sandeep, I think you are describing a scenario where a contractor cut some holes through the web (vertical portion) of some I-beams, and the contractor reinforced it with some additional material.

This is not the site to find information on evaluating whether the contractor's fix was appropriate.

A good place to start is AISC's web site. Read up on steel beam web penetrations and web reinforcement. There is a procedure for evaluating the strength of a reinforcement scheme, and for evaluating how large a hole can be made through the web.

And you MUST consult the building's structural engineer. Since his name is on the structure's design, he will have final say on what would be appropriate. He'd want to know about the change as well, since his insurance is covering the design.

As stated, this is not the site for questions of this sort. We are primarily a residential DIY site for DIYers and not a resource for contractors to use to get information on how to construct projects of a large commercial scope.

Engineering of this sort cannot be accurately obtained over the internet.
