Performance-Based Assessment of RC Building with Short Columns Due to the Different Design Principles

Many factors affect the earthquake vulnerability of reinforced concrete (RC) structures, constituting a large part existing building stock. Short column in RC structures is one reasons for damage. Significant damages may occur due to brittle fractures structural elements when shear resistances are exceeded under effect high stress short columns formed architectural and topographic reasons. This study created models three situations: hill slope effect, band-type window mezzanine floor, which cause formation. The analyses by SAP2000 were compared with reference model no columns. Structural performed separately according strength-based deformation-based design approaches updated Türkiye Building Earthquake Code (TBEC-2018). formation; effects on soft-storey irregularity, relative storey drifts, force, plastic rotation columns, roof displacement, base force damage levels investigated. As result analysis, it was determined that drifts from first floor decreased significantly caused second fall into status. In addition, short-column formation significant increase both demand
