Reliability Analysis for Tension and Compression Designs of Steel Truss Elements Using Vietnamese Codes
https://orcid.org/http://orcid.org/0000-0002-8784-9458
This study performs a reliability analysis to assess the probabilistic safety of truss members designed with Vietnamese design codes. Based on the investigations, the suitability of the load and the resistance factors currently specified in the design codes are examined. For this purpose, two truss structures are first designed using the load and actions code (TCVN 2737-2020) and the current design code for steel structures (TCVN 5575-2012). Monte Carlo simulations are then carried out for the design solutions. The results disclose that the reliability indexes associated with strength limit states are relatively close to the target index of 3.8, recommended in Eurocode. Overdesigned compression designs are found when the resistance factor of 0.9, currently specified in the national design code, is utilized. Hence, the compression bars are redesigned with modified resistance factors of 0.95. The reliability analyses are again performed, and the results reveal that the resistance factor of 0.95 is more reasonably applied.
