👉For Building Structural Engineers (RCC, Formwork & Reinforcement) job entrance exam👷♂️
🏷1. What are the key checks before fixing formwork for beams and slabs?
⏺Line, level, dimensions, rigidity, alignment, tightness of joints, and proper supports/props.
🏷2. How do you determine the spacing of props and supports for slab formwork?
⏺Based on slab thickness, formwork material, load calculations, and manufacturer’s recommendations.
🏷3. What is camber in beams and slabs and why is it provided?
⏺A slight upward curvature provided to compensate for deflection after removal of formwork.
🏷4. What are the common causes of formwork failure?
⏺Inadequate bracing, overloading, poor workmanship, weak supports, and premature removal.
🏷5. What is the difference between lap length and development length?
⏺Lap length joins two bars; development length ensures full stress transfer between steel and concrete.
🏷6. How do you check lap length on site?
⏺Measure against drawings and codes (e.g., 40–50 times bar diameter depending on conditions).
🏷7. What is anchorage length?
⏺The length of reinforcement embedded into concrete to develop required bond strength.
🏷8. What checks are done for reinforcement in beams?
⏺Bar size, spacing, cover, stirrup spacing, hooks, laps, and alignment.
🏷9. Why are stirrups provided in beams?
⏺To resist shear forces and hold longitudinal bars in position.
🏷10. What is the purpose of column ties?
⏺To prevent buckling of longitudinal bars and confine concrete.
