The objective is to identify the appropriate EPH capable of maintaining bridge surface temperatures above freezing under various climatic conditions. The study uses "Mean Minimum Temperature" data from the U.S. Climate Normals dataset (1991-2020) to ensure simulations are applicable across diverse regions. By systematically varying the power of the embedded heat source, the research identifies the minimum required EPH input to maintain the bridge deck surface at 3°C, preventing ice formation. Key findings indicate that the developed 3D FEA model effectively avoid ice formation on bridge surfaces by using an external electrical energy source connected to transverse steel rebars. Parameters such as outside temperature, wind speed, and EPH location significantly influence the performance of the heating system. A stress analysis confirms the feasibility of this method, providing guidelines for designers. The study concludes that maintaining a spacing of 12 inches (0.3048 meters) is optimal for the EPH placement and for ensuring structural integrity the EPH heat flow should not exceed 1.22kW.application/pdfEnglishEngineering, MechanicalEngineering, CivilMaster's Thesis2024-08-27
