Q. The thickness of the flange of a Tee beam of a ribbed slab is assumed as

View solution

Q. In a singly reinforced beam, if the permissible stress in concrete reaches earlier than that in steel, the beam section is called

View solution

Q. The length of the lap in a compression member is kept greater than bar diameter x (Permissible stress in bar / Five times the bond stress) or

View solution

Q. In testing a pile by load test, pile platform is loaded with one and half times the design load and a maximum settlement is noted. The load is gradually removed and the consequent rebound is measured. For a safe pile, the net settlement (i.e. total settlement minus rebound) per tonne of test load should not exceed
