(Assume concrete cover to be 40 mm)

Question 6

Shear key is provided when factor of safety in which of the condition is less than the permissible.

Question 7

What will be a Net upward pressure unreinforced concrete wall footing. If thickness and load carrying capacity of a wall is 72 cm and 600 kN per meter (SBC = 200 kN/m2) Assume weight of footing is 10% of load on the wall

Question 8

A concrete beam of 10 m effective span and 1m effective depth is supported on 500x500 mm2 columns. If the total uniformly distributed load on the beam is 10 MN/m, the design shear force as per working stress method is
