Column B support moments

Analysis moment = 198 kNm in both directions

Column strip /WSdcs = 0.75 x 198 = 149 kNm BS 8110

= 2255 mm2

Use 13T16 (2613 mm2) top in column strip. Provide 9T16 @ 150 mm crs. in central 1.3 m and 2T16 @ 300 mm crs. on either side

Check whether minimum moment required for punching shear has been met. With = -0.125

This is to be carried over a width of 0.3/. Since V^ includes for a loaded width of 5.2 m, it is assumed that the larger panel width may be used.

By inspection reinforcement (9T16 in central 1.3 m) is sufficient OK

Middle strip (using average panel width)
