Effect of Strong Column Weak Beam Concept on Seismic Capacity of Buildings of Varying Heights: A Review

Abstract

The strong-column-weak-beam (SCWB) layout philosophy in which plastic deformation is authorized to arise most effective with inside the beams whilst the columns continue to be basically elastic is broadly followed in seismic layout codes for metallic second frames. Under this yield mechanism, the seismic strength is dissipated ordinarily with the aid of using the plastic hinges with inside the beams and on the column bases. The relative plastic flexural capacities of the beams and column bases can drastically have an impact at the response of a SCWB frame. During beyond earthquakes column plastic hinges are extra crucial than beam hinges which offers upward push to worldwide structural harm and excessive existence threatening risk. All the structural components transfers their forces through column and then column shares it with foundation to soil, so u can imagine if column fails whole structure can collapse this is strong beam weak column concept.
