When the characteristic stength for concrete is based on the cube strength it is necessry that it is multiplied by 2/3 because the stength in bending is always significantly less than that resulting from the cube strength”. “The ultimate load theory analysis is based on the assumptions that plane surfaces remain plane during bending and there is no contribution to the bending strength of the beam from concrete in tension. The strain therefore varies uniformly down the beam section. The stress diagram however is not linear but has a rectangular parabolic shape as shown below.

” “Briefly illustrate with the aid of annotated plans and elevation sketches, examples showing the differences between functions of braced and unbraced (perimeter and internal) columns required to support loads in a typical four-storey rectangular reinforced concrete structure.
