**5.2 Comparison based on nonlinear static analysis in ETABS**


**Case 1:** IS-1893 V (kN): 7200 D (mm): 430

results of RCA and SEMAp are matching in terms of moments (**Table 3**; [5]). The results of ultimate strain limits for NC-PL of EC-8 and SEMAp are matching (**Table 3**; [9]). Similarity is there in ultimate rotation values of RCA and SEMAp (**Table 3**; [10]). The ultimate rotation values of columns designed using ACI-318 and EC-8 are found to be in similar range and are higher than rotation limit of IS designed building (**Table 3**; [10]). The variation in moments for all cases is shown
