摘要：
Seismic performance evaluation of non-seismically detailed reinforced concrete (RC) buildings requires proper analytical modeling approaches for beam-column joints which are most vulnerable parts. This study investigates the influence of beam column joint modeling assumptions on performance evaluation of non-ductile RC buildings. Numerical simulation model includes truss-based elements for beam-column connections and fiber-based elements for beams and columns. Two-dimensional four- and six- story reinforced concrete frames of an existing RC building are designed and analyzed by conducting incremental dynamic analyses. Column chord rotations and corresponding strains are compared with code provisions for performance assessment of non-ductile RC frames.
