2. Type a unique Name and (optional) Description for this load combination.
3. Select the Type of combination method to use.
• Linear – A pure algebraic load combination in which the results of all constituent cases will be algebraically added.

Ex.: $f1×L1+f2×L2+f3×L3$

• SRSS – The square root of the sum of the squares method of combination.

Ex. $f1×L1+fSRSS×f2L22+f3L32$

• ABS – Algebraic combination of absolute values.

Ex.: $f1×|L1|+f2×|L2|+f3×|L3|$
