Unlike many foreign authors who focus on ACI (American) codes, Rajagopalan’s work is meticulously aligned with the , specifically IS 1343 (Code of Practice for Prestressed Concrete).

Plain concrete is exceptionally strong in compression but very weak in tension. When subjected to bending loads, the bottom of a beam stretches (tension) and cracks easily. 2. The Prestressing Solution
