Abstract
The aim of this research was to comparatively evaluate the structural response of a 21 m centrifugally reinforced concrete (C.A.C.) pole subjected to wind loads, applying the methodologies of ASCE 74 and CFE J6100-54 standards. The pole was modeled in SAP2000 v22 using both static and time-history dynamic analyses, considering service, maintenance, failure, and extreme wind load scenarios. Wind data were generated using the NOWS simulator for velicities up to 27.78 m/s. Results show a maximum displacement of 0.28 m under CFE and 0.20 m under ASCE, while maximum bending moments reached 145.92 kN.m and 133.47 kN.m, respectively.
Statistical validation using ANOVA revealed non-significant differences (Fcalc=2.17 < Fcrit=4.26; p=0.144 > 0.05), confirming the technical equivalence between the standards. It is concluded that ASCE 74 provides higher accuracy by incorporating gust response factors (GRF) up to 1.08, enhancing the design against transient loads. This research establishes a robust methodological framework to improve structural resilience and the safety of urban electrical infrastructure.
