Hi there,

Can you not use an 'agss' section with zero bottom/top flange eccentricities, as noted in the Help System?

it is possible to define 'agss' element only for single section such as 1UNP80,but it can`t be defined as double section such as 2UNP80

[seismosoft]

If you are using 2UNPs, then we suggest you use either a 'rhs' section or two coincident nodes elements with 'agss' sections.

thanks for helping me,but I suggest you that consider UNP section and double section in the next version of this software
thanks

Sure, we will certainly consider your suggestion, which may facilitate user input.

Note, however, that from a results point of view, nothing will change, since the program (which currently does not model section warping or local buckling) will not really distinguish between the explicit modelling of a double-UNP section and the equivalent procedure described in our previous response.

But, we repeat, it may certainly assist users in defining their models more quickly, hence something worth considering indeed.
