Which of the following statement is correct regarding assumption of 'limit state of collapse' in RCC design?

I. The tensile strength of the concrete is ignored

II. For design purposes the partial safety factor m, equal to 1.75 shall be applied 

Explanation:

Assumptions of Limit State Method
In the case of the limit state method of designing, There are some conditions regarding stress-strain relationships, material behaviours, etc. These conditions are known as the assumptions of the limit state method of design. 

Assumptions

• The plain section remains plane before and after bending; these assumptions ensure that the strain diagram is linear.
• At the time of flexural failure, the maximum strain in concrete at the topmost fibre will be 0.0035
• The maximum compressive strain in concrete in axial compression is taken as 0.002
• The stress-strain curve for the concrete is parabolic up to the strain of 0.002, and stress will be constant up to the strain of 0.0035
• The tensile strength of concrete below the neutral axis is ignored; it says that the tensile strength of concrete is ignored.
• Maximum strain in steel at the time of failure should be greater than fy/1.15Es + 0.002
• The safety factor for concrete is 1.5, and the partial safety factor for steel is considered 1.15 for designing concrete structures.
