Thanks BulbTheBuilder EI for your advice. I will look into it.

BulbTheBuilder EI: I do not see your sketch. In fact I cannot see any Attachments from anybody. What am I doing wrong - or what am I supposed to do? Can someone give me directions? TIA

I do not know how to see your sketch/STAAD info. How do I do that?

Hi paddingtongreen, The pull angle will be 60 to 75 degree to the horizontal - the cables will actually be fastened to a Lifting Beam above this sort of a platform. I do not know the vertical distance from the platform to the lifting beam above and will be checking it with the customer. I am...

STABILITY BRACING I am designing a sort of Double Lifting Beam. Actually, they are a pair of Parallel Beams 4 ft apart. The beams are 60 ft long and W8x31. The beams are connected in the transverse direction by W8x31 beams as well. Flanges and Webs welded like a moment connection. (All beams...

If you do not provide reinforcement near the top of slab at the supports, slab has potential to crack due to negastive BM at the support. And those cracks can be ugly.

Hi msquared48 and concretemasonry, Thanks a lot for your taking time and answering. It means a lot to me because I do not any other resource with this type of background. This machinery was going to be located above a sandy soil with 65 - 85% moisture (quick sand condition), which was...

The machine (motor and generator 40,000 lb each) will sit on a concrete mat approximately 3 ft x 16 ft x 26 ft. The pad will be sitting and doweled to the rock. 600 RPM each. High rocking torque but not much vertical/horizontal unbalanced forces. Actually, I plan to excavate rock 6 - 12" so...

Per OSHA, the anchor point is to be designed to 5000# at failure. So, I calculate the ultimate capacity of the connection and compare that to 5000#. As far as members are concerned, OSHA does not say 5000#. So, I would design the members for the load recommended by the Lanyard Vendor - if I...

cd and gh will not act as shear walls because their lengths are too small compared to the total shear wall length of ab, and ef in the North-South direction. This is basic stiffness priniples. Diaphragm will span full width from ab to ef. If you prefer you can always design cd and gh as shear...

I am not giving any help to you, but, I have a question to supplement your question. I am analyzing an existing concrete moment frame with shear wall on one side and rigid (floor) and flexible (roof) diaphragms. I plan to use STAADPRO 2000 also. In modelling, should I just use the concrete...

I worked on a project involving second floor of a cafeteria structure. Baking and dispensing of food was done on first floor. Water operations occurred on second floor. The floor had extensive damage (including rebar corrosion, spalling, cracking, leaking of contaminated washwater, etc.)...
