Hello, I received Academic License Key for SeismoStruct 2016 from you. In reply I found a message that "We kindly remind you that the academic version of SeismoStruct 2016 supports code-based checks of up to twenty members." I can not understand the meaning of that message. Can I use this same Licence Code for upto 20 Users? or anything else. Please someone help me.

It mean that the program supports code-based checks of up to twenty structural members in the same project.You will need to use a commercial version for more members.
