JNTU B.Tech III ADVANCED STRUCTURAL ANALYSIS Previous Question Paper (May - 2019 - R16)

Determine the horizontal thrust at the support of a parabolic two-hinged arch with the area of the cross section of the crown is 4.5×10^-2 and moment of inertia is 3.375 × 10^-4. The rise of the arch is 14.875 m and its span is 85 m. Find out the maximum moment at the crown, if the arch carries UDL of 15 kN/m.

Determine the vertical displacement of joint B, as shown in figure 1. The area of cross-section of member is 550 mm² and E = 200 kN/mm².

Using the slope-deflection method, find out the moments in the frame ash shown in figure 2.

Analyse the bend shown in figure 3 by moment distribution method.

Let us consider the continuous beam as discussed in example. The beam is shown in figure 4. in this beam the support B sinks by 15 mm; E = 200 kN/mm²; and I = 150 × 10⁶ mm⁴. Using the Kani’s method, determine the end moments.

Analyse the rigid frame shown in figure 5 using the kani’s method.

Analyse the continuous beam shown in figure 6 by flexibility method.

Analyse the frame shown figure 7 by stiffness method.

In a multistoreyed building, the frame shown in figure 8. are spaced at 4 m intervals. Dead load from the slab is 3 kN/m² and the live load is 5 kN/m². Analyse the beam BC for midspan positive bending moment. Self weight of the beams may be ignored. Use two-cycle moment distribution method.

Construct the influence line for shear using Muuler-Breslau’s principle at section X of member BC of a continuous beam as shown in figure 9. Determine the maximum shear at X when the beam carries a UDL of 25 kN/m which can occupy a single span fully or a portion of a span. EI of the ebam is constant throughout.
