Abstract

The invention relates to a sleeve joint tension capacity evaluation method taking grouting compactness into consideration. The sleeve joint tension capacity evaluation method taking the grouting compactness into consideration includes providing values of key parameters A and B according to a test, computing actual steel bar-grouting material bonding force according to a steel bar-grouting material bonding force slip model, computing tension capacity of jointed steel bars according to a jointed steel bar tension capacity computational formula, and providing sleeve joint tension capacity by comparing the steel bar-grouting material bonding force with the jointed steel bar tension capacity. The sleeve joint tension capacity evaluation method taking the grouting compactness into consideration is capable of evaluating the sleeve joint tension capacity through sleeve and steel bar design parameters.

Description

technical field [0001] The invention relates to the field of calculating the tensile bearing capacity of sleeve joints, in particular to a method for evaluating the tensile bearing capacity of sleeve joints considering the compactness of grouting. Background technique [0002] In recent years, with the development of structural industrialization, prefabricated buildings have become one of the main structural forms that are vigorously promoted and developed by current architectural industrialization. However, compared with cast-in-place buildings, the integrity and connection quality of prefabricated buildings are still hot issues of concern, and the wet connection in the existing connection methods mainly uses grouting sleeve joints. Grouted sleeve joints use non-shrink grout as the bonding material to connect the reinforcement to ensure continuity of load transfer. The sleeve is usually manufactured by casting process or machining process. The grouting material is cement a...
