Abstract
ABSTRACT
Architectural needs may require changing column orientation from floor to floor, in such a
case, the design of this connection needs extensive care. In this paper, the structural
performance of reinforced concrete column connections based on their positional categories,
such as interior, exterior, and corner, under the effect of varying dimensions and loading
stages was analytically investigated. Using finite element analysis, the study employs
advanced modeling techniques, including 8-node elements for concrete and truss elements
for steel reinforcement. Twelve reinforced concrete columns were simulated by the aid of
ANSYS program to examine the intersection positions (interior, exterior, and corner) and
assess the column dimensions and their effect on capacity. The analysis examined the crack
patterns, failure modes, and load-deflection behaviors for interior, exterior, and corner RC
columns with different dimensions. The finite element modeling study revealed that the
interior columns exhibit higher load capacities than the exterior and corner columns. Crack
patterns evolve progressively with load increments, with interior columns showing better
resistance due to enhanced confinement. Also, the load-deflection relationships indicate
significant differences based on column position and dimensions, with stress distributions
highlighting critical failure regions. Finally, a proposed method to predict column
connection capacity was introduced.
