Study of Strong-Column Weak-Beam Concept on Seismic Capacity of Buildings of Varying Heights

Abstract

The design philosophy of the strong-column weak-beam (SCWB) in which plastic flexibility is allowed
to occur only in beams while the expanded columns are widely accepted in the independent
earthquake design codes of steel. Under this method of harvesting, earthquake power is dispersed
mainly by plastic hinges on beams and columns. The plastic strength of flexible beams and column
bases can greatly affect the response of the SCWB framework. During the lasting earthquake, the
plastic columns are more important than the beam gaps that cause damage to the global structure
and the high risk of life. All parts of the structure transfer their power through the column and the
column shares it with the base and soil, so you can imagine if the column fails to form, all of it could
fall into this fragile weak concept of the column.
