There are several ways to define the structural mass in SeismoStruct.
You can use the elements' self mass by specifying the materials specific weight, you can transform gravity loads to masses and/or you can use specific mass elements. Refer to the Gravity and Mass page of the Program Settings and the corresponding page of the program's help.
