Based on the influence of lateral constraints, there are two categories of constraint areas within a cross-shaped partially encased composite (CPEC) column: strong constraint areas (SCAs) and weak constraint areas (WCAs). Due to the diverse constraint effects of profile steel on concrete, dissimilar...
