concrete beam - g-section example

A single G-section beam will be analyzed with RCsolver. The following data is available:

a) Section properties: B_eff = 0.78 m, h = 0.75 m, Bw = 0.25 m, tf = 0.16 m, c = 50 mm, concrete: C25/30, Reinforcement steel: B500C, proposed tensile reinforcement: Ø18, proposed shear reinforcement: Ø10, number of stirrup legs: 2.

b) Beam properties and loading: L = 3 m, Mleft = -150 KNm, Mcenter = 85 KNm, Mright  = -180 KNm, Vleft = 120 KN, Vright = -140 KN.

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