concrete column - Rectangular section example

A single rectangular section column will be analyzed with RCsolver. The following data is available:

a) Section properties: b = 0.5 m, d = 0.6 m, c = 50 mm, concrete: C25/30, Reinforcement steel: B500C, proposed tensile reinforcement: Ø16, proposed shear reinforcement: Ø10, number of stirrup legs: 4.

b) Column properties and loading: h = 3 m, Mtop,y = 90 KNm, Mtop,z = 100 KNm, Mbot,y = -110 KNm, Mbot,z = -120 KNm,  Vy = 90 KN, Vz = 50 KN, Ntop = 400 KN (compression), Nbot = 480 KN (compression).

Objective: Design the concrete column and calculate the required tensile and shear reinforcement.
