ABSTRACT

This study aims to analyze the impact of the in-situ anchoring method on the stress performance of temperature-prestressed reinforced concrete beams. A numerical model of the prestressed beam opening structure was constructed using the Midas FEA simulation software, and the stress conditions of the beams under the in-situ anchoring method and conventional anchoring method were compared and analyzed by comparing the deflection data of surrounding points during the opening process. The results indicate that the stress performance of temperature-prestressed reinforced concrete beams under both anchoring methods during the opening process is essentially consistent, but the construction process of the in-situ anchoring method is simpler and more efficient. The comparison confirms the feasibility of the in-situ anchoring method and provides a new perspective for the development of opening technology for this type of beam.
