envelope and concomitant forces

[borja1980]

hi. i am working with sap2000, and i am teiying to develop and application for the automatic calculation of the reinforcements requiremnst of a concrete structure. i already know how to obtain the envelope of different load cases, but i need to be able to obtain the concomitant forces in a given point. i mean, when i calculate the envelope of the bending moment, i know the max and min value of the bending momennt in every pointin the structure, but i need also to obtain the axial force associated in that particular point, with the given bendin moment. i would like to know if somebody knows how to do it.
thanks

I don't think it is possible but you might be missing something. Sometimes the maximum and corresponding values might not be of such importance: imagine a case in which you have a maximum value for one of the force/moment but the corresponding value of the other is small. There might be a case in which you might not have maximum values but the combination of both may give the biggest reinforcement area required. I advice you to get all these case results listed in MS Excel (for example) and use some formulas to calculate the required reinforcement in every case and then consider the biggest reinforcement required.

Hi,

You can get the concomitant forces in version 17, display tables>options
