The user specifies the splice levels (See Section 2.12.2). For purposes of design the program assumes that the splice occurs at the floor level (for purposes of construction the splices may actually occur some height above the floor level). The program then assigns the same column size to all levels between splices based on the worst design condition between splices. The only thing the splice data is used for is to determine where column sizes can change. It is not used in calculating design moments.
