Transfer of reinforcement and Tendons from RAM Concept to ISM

Hi,

From reading elsewhere on the internet, I understand that reinforcement and tendons are currently not supported in the transfer from RAM Concept via an ISM repository. Is this correct and if so at what date will the ability be available?

Thanks,

Ben

 

 

 

  • Concrete is a wonderful material if you want to use it in compression. However, its tensile strength is only a fraction (say, one tenth) of its compressive strength. That means for elements which are subject to tensile stresses, such as beams, concrete on its own is not ideal.

    Steel, on the other hand, is very good in tension. That makes for a happy marriage. Concrete and steel. The concrete takes the compressive stresses in the tops of beams, and steel reinforcement bars take the tensile stresses in the bottoms of beams, for instance.

    Another way to use steel, however, is to use “tendons” made of several “strands” of very high tensile steel wires. Those tendons are stretched within (or without) the concrete, and act in a way like a huge rubber band around a series of children’s blocks. In the same was as the rubber band imposes a significant clamping force keeping the array of blocks in compression, the stressing tendons do likewise, though with hundreds or even thousands of tonnes equivalent of force (thousands or tens of thousands of kN for those with eyes to see). Hydraulic jacks are used to stretch those tendons. That process is referred to as pre-stressing, or post tensioning.

    So, back to the question. The major difference is that with prestressed (tendon) concrete, the system is usually designed to keep the concrete in a state of perpetual compression. A gift that conventional (bar) reinforcement does not possess. That allows for better crack control and also better control over the profile (eg “sag”) in beam elements, slab elements and bridge decks. Occasionally, columns are prestressed, and it is quite usual to prestress very tall electrical poles and communication towers. Stressing also allows for improved structural and monetary economy.

    The following sketches give further insight.

  • I have made a file in revit and then exported it to staad pro. After this I did analysis and design in staad and then exported this file in revit through ism. Problem is that I didn't get reinforcement details, it simply provided me the same model as i created in revit. So kindly tell me how i can obtain reinforcement detais in revit through staad pro.

  • You can get concrete reinforcing across from Ram Concept to ISM (and on to Revit), also from Ram Structural System or STAAD Foundation Advanced but not yet from STAAD.pro as far as I know.



  • Hello Sir, 

    is there any method of exporting Analysis and design data from STAADpro/STAADPro connect edition to IFC file.

    Till now i had used ISM respiratory but nothing is written in IFC only i get is modeling detail

  • After this, I did analysis and design in staad and then exported this file in Revit through ism. Problem is that I didn't get reinforcement details, it simply provided me the same model as I created in Revit usps hold mail
