Where:

Parameter	Description
j#	the joint number
n#	the node number
K%, X%, and Y%	The fractional contributions of K-type, X type and Y-type, respectively. Initially the joints will be classed as Y (i.e., K=0, X=0 and Y=1).
C#	the member numbers of the CHORD
CLEN	the length of chord member
D, T	Diameter and thickness of CHORD
B#	the member number of the brace
BLEN	the length of chord member
d, t	Diameter and thickness of BRACE
gap	Distance required to calculate gap factor for K bracing. Initially, the value of GAP is assumed as 0.

Note: All distances are provided in units of inches.
