Tensile stresses
It has been possible to introduce tensile stresses of upto 850 N/mm2 in tendons with the use of this method. But the method is not suited in situations where a high degree of prestress is desired to be induced. Structural elements suited for chemical prestressing are thin walls, shells, slabs, composite columns, folded plates and pipes.
Define Advantages of Shock Transmission Unit? (a) STU is simple to install with minimal traffic disruption. (b) STU can be used for strengthening of existing bridges also. T
Q. Reasons for blockage in pumping concrete ? Concrete pumping is normally adopted in highly elevated locations for which access for concrete trucks is difficult. Construction
Permissible Stresses in Steel As per the Indian code, the permissible stresses in the tendons at the time of initial prestressing should not exceed 80% of the characteristic t
