Question

1) 2) 3) 4) 5) 6) 7) 8) Explain why capacity reduction factors for columns are smaller than ones of beams. Explain in detail for load combinations of strength design per ACI 318. Explain what benefits of using shear reinforcement are. Explain max spacing of shear stirrups per ACI 318. Explain 3 different types of compression members. Explain ACI code requirements for cast-in-place concrete columns. Explain how to find effective flange width of T-beam per ACI 318 (3 different cases). Explain strength design procedure for T-beam design.

Explanation / Answer

1) Because columns are subjected to compressive loads and concrete is good at compression. It can carry the maximum loads and less reduction factor for its strength is required. But beams are subjected to both tension and compression in most of the cases equal tension and equal compression hence more reduction factor is required in order to compensate the tensile forces.
