Capacity of Shear Joints in Applications of High Performance Concrete in Strengthening and Retrofitting of old Concrete Structures

摘要

Along with the introduction of new building materials like high performance concrete (HPC) there has been a regression in building new structures and the maintenance of older concrete structures became increasingly important in the recent decade. Either for strengthening structures or to preserve historical buildings ― later applied concrete usually forms the basis of strengthening or redesign. To use HPC and its advantages for strengthening, the crucial function of a shear joint between old and new concrete has to be observed.
