Question

these are shot questions please answer the all questions it's important for me

1. A tension-controlled concrete member is one in which the tensile strain in the steel reaches at _just as the concrete reaches a compressive strain of least a value of 0.003. 2 The term balanced section refers to a beam section in which the concrete compression strain reaches 0.003 for the same load at which the tensile steel reaches stress. 3. The ACI requires a minimum percentage of reinforcing steel in concrete beams to prevent the condition where the ultimate moment of the section is less than the moment of the section. 4. The ultimate compressive stress in a concrete section is assumed to be a constant value of 0.85f . to approximate the actual --shaped compressive stress at ultimate. 5. If a steel section develops the full plastic moment strength M, then every point on the section has reached the stress of the material.
