Question 41
Open questionCENAT2 marksNeeds review
An RCC beam of rectangular cross section has factored shear of 200 kN at its critical section. Its width b is 250 mm and effective depth d is 350 mm. Assume design shear strength
of concrete as 0.62 N/mm² and maximum allowable shear stress
in concrete as 2.8 N/mm². If two legged 10 mm diameter vertical stirrups of Fe50 grade steel are used, then the required spacing (in cm, up to one decimal place) as per limit state method will be _____Log in to check the answer

A cable PQ of length 25 m is supported at two ends at the same level as shown in the figure. The horizontal distance between the supports is 20 m. A point load of 150 kN is applied at point R which divides it into equal parts.
Neglecting the self-weight of the cable, the tension (in kN, in integer value) in the cable due to the applied load will be ______

Open questionCENAT2 marksNeeds review
The total horizontal and vertical stresses at a point X in a saturated sandy medium are 170 kPa and 300 kPa, respectively. The static pore-water pressure is 30 kPa. At failure, the excess pore-water pressure is measured to be 94.50 kPa, and the shear stresses on the vertical and horizontal planes passing through the point X are zero. Effective cohesion is 0 kPa and effective angle of internal friction is 36°. The shear strength (in kPa, up to two decimal places) at point X is ______

A conventional drained triaxial compression test was conducted on a normally consolidated clay sample under an effective confining pressure of 200 kPa. The deviator stress at failure was found to be 400 kPa. An identical specimen of the same clay sample is isotropically consolidated to a confining pressure of 200 kPa and subjected to standard undrained triaxial compression test. If the deviator stress at failure is 150 kPa, the pore pressure developed (in kPa, up to one decimal place) is _____
