engineering recuitment GATE CE 2023-24 Test Series Reinforced Concrete Structures Limit State Method
A rectangular beam of effective size (300 × 400) mm, reinforced with 4 – 16 ϕ bar is to be designed by two Structural Engineer A and B. Engineer A abides by IS 456:2000 provisions for the stress strain curve (parabolic) of the concrete, however engineer B assumes straight line stress-strain curve of concrete instead of parabola. The difference between the positions of NA (in mm, up to two decimal places without sign) calculated by Engineer A and B w.r.t extreme compression fiber is ____
(Consider construction material as M 20 and Fe 415 and maximum compressive strain is considered as 0.0035 in both cases)Enter numerical value using the virtual keypad. Round off where necessary.
