Explanation:
The limit state method of design is a method of designing reinforced concrete structures that considers the different limit states that a structure can experience during its design life. These limit states include the ultimate limit state (ULS) and the serviceability limit state (SLS).
In the ULS, the structure is designed to resist failure due to excessive stress or strain. In the case of reinforced concrete beams and columns, the failure criterion is based on the maximum principal strain theory. This theory states that failure occurs when the maximum principal tensile strain in the concrete reaches a certain limit.
The maximum principal strain theory is based on the assumption that the concrete behaves in a linear elastic manner up to the point of failure. This means that the stress-strain relationship of the concrete is assumed to be linear up to the point of failure. The maximum principal strain theory is also based on the assumption that the concrete is isotropic, which means that it has the same properties in all directions.
The maximum principal strain theory is used to design reinforced concrete beams and columns by calculating the maximum principal tensile strain in the concrete and comparing it to the allowable limit. If the maximum principal tensile strain exceeds the allowable limit, then the section is considered to have failed.
In summary, the failure criterion for reinforced concrete beams and columns in the limit state method of design is based on the maximum principal strain theory. This theory is used to calculate the maximum principal tensile strain in the concrete and compare it to the allowable limit to determine if the section has failed.
