Thermal force calculation with bearing pad for multi-column interior bent with varying column heights

Please check the calculation for fixed bearing and for elastomeric bearing pads , the calculation is similar.

Very detailed theory related to thermal force calculation is shown in the RCpier Tutorial Manual.

Vinay,

That's not the answer im looking for. I'd like to know how the program calculates the out-of-plane stiffness when more than one column is modeled with varying heights and different column and drilled shaft diameters with elastomeric bearing pads. Can you please explain. The screenshot provided is not explaining that.

Thanks,

I'm looking into this issue and will get back to you at the earliest.

Hi Danny ,

Did Danny's questions get resolved? I too wondered how RCpier handles varying heights.

I created the Service Request: 7001531346 and emailed you the answer.

No. It was never answered

This was response provided to Benji Michael:

This is the response from the Software Development manager .

 “I made a quick model to test the out of plane (OOP) loading and the effect due to that. Following are some snapshots of the model. I have attached the file also in here. In the engine source code it clearly shows the element stiffness matrix considers the moment of inertia about the minor direction that is aligned to the OOP direction. Both along transverse and about OOP moment DOFs are considered in the stiffness formulation. Stiffness terms are exactly the way Timoshenko has provided.

Please let me know if this is the information you are looking for.

Please let me know if you need any additional information.

Thanks & Regards,
