Which outcome occurs when seismic loading exceeds rebar capacity?

💡 Explanation

Seismic loading exceeding rebar tensile strength initiates sectional yield, because of insufficient rebar. The mechanism of subsequent **compressive failure** causes concrete to spall and the structure to fully collapse; therefore buckling occurs, rather than elastic deformation.
