Shear Performance of Horizontal Joints in Short Precast Concrete Columns with Sleeve Grouted Connections under Cyclic Loading
In this study, two short precast concrete columns and two cast-in-situ concrete columns were tested under cyclic loads. It was shown that the sleeve grouted connection was equivalent to the cast-in-situ connections for short columns when the axial compression ratio was 0.6. In order to determine the influence of the axial compression ratio and the shear-span ratio on the shear capacity of the h...
متن کاملExperimental study of grouted sleeve lapping connector under tensile load
The performance of the grouted sleeve lapping connector that is used to connect reinforcement bars in a precast concrete structure is studied. A total of 63 specimens, varying in bar diameter and lap length, were tested under tensile load. The failure modes, ultimate tensile strength values and load-displacement curves of the specimens are discussed in the study. Two equations are proposed for ...
متن کاملEffect of sleeve length on deformation properties of grouted splices
Tests on 12 grouted splices were performed to investigate their deformation properties under tensile loading. Test variables included diameter and type of spliced bars and the size of splicing sleeves. Finite element method based models of the splices were built, verified and used to investigate the effect of sleeve length on the deformation properties of the grouted splices. The sleeve length ...
متن کاملComputational and Experimental Mechanical Modelling of a Composite Grouted Splice Sleeve Connector System
Owing to its controllable tolerance, simple operation and no need for welding at construction site, the composite system involving grouted cement material, steel material and ductile iron material is widely used as grouted splice sleeve (GSS) connector for connecting precast concrete structures. However, the current design recommendations for such a composite connection system do not accurately...
متن کاملStudy on Bearing Capacity of Prestressed Pipe Pile Foundation Under Horizontal Load
Received: June 12, 2017 Revised: October 24, 2017 Accepted: November 03, 2017 Abstract: Background and Objective: Prestressed high strength concrete pipe pile (PHC) shows brittle fracture when subjected to more than its own bearing capacity. Therefore, the non-prestressed steel bar is added to the PHC pipe pile, that is, the mixed reinforced pipe pile (PRC). The mechanical behavior of PRC group...
