A simply supported W18 x 119 A992 steel beam with 8 meters in length was subjected to a service load of 990 kN/m, with a dead-to-live load ratio of 1:2, excluding the beam weight. Due to the excessive deflection, it is then decided that an additional W18 x 119 column with a length of 7.0 meters is to be placed at the midspan of the beam as additional support. The said action will be made to minimize the deflection to 3 mm. If the column being added is fixed at the bottom and pinned at the top, evaluate if W18 x 119 can withstand as support. Use a recommended value for K. Evaluate using LRFD and ASD.

Question
A simply supported W18 x 119 A992 steel beam with 8 meters in length was subjected to a service load of
990 kN/m, with a dead-to-live load ratio of 1:2, excluding the beam weight. Due to the excessive deflection, it
is then decided that an additional W18 x 119 column with a length of 7.0 meters is to be placed at the midspan
of the beam as additional support. The said action will be made to minimize the deflection to 3 mm. If the
column being added is fixed at the bottom and pinned at the top, evaluate if W18 x 119 can withstand as
support. Use a recommended value for K. Evaluate using LRFD and ASD.
