A cable is used to support a large poster (sign), 40ftx110 ft, that will be hanging from the wall of a high rise building. The weight of the poster is about 500 lbs.
If cable is supported at its two ends, how is the tension calculated as a function of mid-span deflection?
Thanks for the help.
We have HSS columns in a freezing area -4F,(-20C). The floor is an 8 in reinforced concrete on top 2 layers of rigid insulation on top 6 in heated slab. The temperature below the heated slab is 40F,(+4C). Constant condensation is expected in the columns. How to get rid of the condensation water...
Sorry, I just posted this on the wrong forum.
When I worked for an oil company, I saw big water tanks that accompany rigs put right on the grade. Now when designing a slab on grade for a warehouse, My boss asks for 8 inches thickness and two layers of reinforcement.

we are assessing the condition of a 11-story building. The assessment should include its resistance to lateral loads. The building is more than 60 years old and is steel framed.
We modeled the building using RAMAdvanse. The base shear we are getting is different from the base shear using static...
I need to know about Autodesk Revit. If you use it, Please tell me how different it is from AutoCAD in terms of applications, time, and efficiency.
Thanks

I wonder if rotating the new angle 180 degree about their X axis so that the legs touch the original ones would solve the problem. One more thing, what is the nature of the inadequacy of the top chord?
According to the Brick Industry Association's Technical Notes 3A "The elastic modulus of grout is computed as 500 times the compressive strength of the grout in accordance with the MSJC Code. In general, the elastic modulus of grout and the elastic moduli of brick or structural clay tile and...
I think the difference between a cable and any other section is the flexural stiffness (EI), in the case of a cable, it is very small. if you know the flexural stiffness, then you can model the cable using any software such as SAP2000 and assign the appropriate stiffness and analyse it.
Please...

I wonder if it is necessary to consider a horizontal point load of certain magnitude to account for the possibility of impact due to a car crash into a column in a parking garage?
I'd like to know the code has considered this point.
Thanks
In addition to what SlideRuleEra suggested, I'd request to use concrete with higher strength about 5" bellow and above the joint. Does this make any sense?
Thanks
