Abstract
AIM: This study aimed to develop a method of selecting 3D configurations for composite reinforcement cage of bridge structure supports.
METHODS: The proposed method is based on key design parameters, including structural specifications of supports, mechanical properties of composite materials, operating conditions, and economic factors. The method includes an analysis of available 3D reinforcement configurations, assessment of the effect of various factors on the selection of the best cage configuration, mathematical modeling of strength characteristics, and multi-criteria improvement of the options. In addition, we use a taxonomic approach, allowing the configurations to be ranked by a complex indicator of their proximity to the model solution.
RESULTS: The study allowed to develop a consistent approach to the selection of a 3D reinforcement configurations based on specific properties of composite materials. We have developed calculation algorithms and illustrative applications to demonstrate an increase in the load-bearing capacity, durability, and economic efficiency of structures. Tables of comparative characteristics of different types of composite reinforcements are provided along with examples of calculating the reinforcement area for eccentrically compressed elements.
CONCLUSION: The proposed method increases the reliability, durability, and economic feasibility of composite reinforcement cages for bridge structure supports. The study is focused on the adaptation of conventional reinforcement configurations to the anisotropy and Hookean behavior of composite materials before failure. Experimental data and practical examples confirm the effectiveness of the proposed approach, which is recommended for designers of bridge structures.
