A roof system consists of 300 mm x 300 mm columns at spacing of 5m and 4m in two mutually perpendicula directions, as shown in Figure below. B \300×300 mm Columns B2 More than 2@ |4 m Each 中十 More than 3 @ 5 m each Beams run in both directions over the columns having mor than two spans in each direction. Design and detail the 1s interior long beam (B2) if the total factored load is 40 kN/1 thickness of slab = 125 mm, C-20 concrete, Grade 420 stee and live load is less than three times of dead load. Select U customary bars. Note: design the beam as rectangular section no need to go fo T-beam check.

Transcribed Image Text:A roof system consists of 300 mm x 300 mm columns at a
spacing of 5m and 4m in two mutually perpendicular
directions, as shown in Figure below.
300x300 mm Columns
B2
More than 2 @
4 m Each
More than 3 @ 5 m each
Beams run in both directions over the columns having more
than two spans in each direction. Design and detail the 1st
interior long beam (B2) if the total factored load is 40 kN/m
thickness of slab = 125 mm, C-20 concrete, Grade 420 steel,
and live load is less than three times of dead load. Select US
customary bars.
Note: design the beam as rectangular section no need to go for
T-beam check.
