Question

Consider the singly reinforced beam shown in the figure below:


At cross-section XX, which of the following statements is TRUE at the limit state?

• A. The variation of stress in linear and that of strain is non-linear
• B. The variation of strain is liner and that of stress is non-linear
• C. The variation of both stress and strain is linear
• D. The variation of both stress and strain is non-linear

Answer 1

The correct option is B The variation of strain is liner and that of stress is non-linear

Under the assumption of LSM of RCC beam
The variation of strain at x-x


The variation of stress at x-x
