Mechanical properties of full-grouted sleeves with grouting defects

Prefabricated concrete structure is an important aspect of the building development in China, while grouted sleeve connection represents a key tool for on prefabricated parts. Various grouting defects may arise during prefabrication and actual construction processes, thereby causing unsafe among components. Here, we report determination mechanical properties full-grouted with defects，using defect position (end defect, middle uniform unilateral horizontal defect) length as test variables. We generated total 11 groups specimens, one group standard specimen. All specimens were subjected to unidirectional tensile test, failure mode, ultimate bearing capacity, load-slip curve, load-displacement curve well load-stress obtained. Meanwhile, ANSYS software was used numerical simulation. Notably, our results corroborated experimental findings. The detailed profiles defects, described this paper, are expected serve both baseline reference further investigations.
