Code No: C4CE02 05 IV B.T ech. (CCC) Regula r Exami nat ion s, Dec ember 2008 ADVANCED STRUCTURAL ENGINEERING (Civil Engineering) Time: 3 hours Max Marks: 100 Answer any FIVE Questions All Questions carry equal marks 1. Design an RC slab culvert for a national highway to suit the follwing data a two- lane carriage way (7.5 m wide) footpaths on either side (1 m wide) Clear span = 6m Wearing coat = 80mm Width of the bearing = 0.4m Materials : M 20 grade concrete Fe 415 grade HYSD bars. Loading : IRC class AA tracked vehicle Design the RC deck slab and sketch the details of reinforcements in the longitudinal and cross-sections of the slab. [20] 2. An RC T-beam Girder bridge is having the following data. Clear width of road way 7.5m Span (c/c of bearing ) 14.5m Live load IRC class AA tracked vehicle Average thickness of wearing coat 80mm. Materials M 20 and Fe 415 Using courbon’s method compute the design moment and shears, design the deck slab and main girder. Draw the details of reinforcement in the deck slab and main girder of T-beam girder bridge. [20] 3. A pratt truss girde r through bridge is prov ided for single broad gauge trac k. The effective span of bridge is 50 m the cross girders are spaced 5m a part.The stringers are spaced 2m between cente r line s. 0.7Kn/ m stock rails and 0.5 Kn/m chec k rails are pro vid ed. Sleepers are spaced at 0.5m from cen ter to ce nt re and are of size 2.8m X 250 mm X 250 mm. Weight of timber may be assume d 7.5Kn/m 3 the mai n girder s are provided at a spacin g of 7m betwee n the ir ce nt er lines. Des ign the central vertical and diagonal of central panel. The bridge is to carry standard main line loading. [20] 4. A deck type plate girder bridge is provided for a single broad gauge track and sta ndard mai n line loading. The total span of main girder from ce nt er to cent er of bearin g is 24m. The main girders are provided at a spa cing of 1.3m between thei r center lines 0.6 Kn/m stock rails and 0.4 Kn/m guard rails are pro vide d. The weight of fastenings may be taken as 0.2Kn/m the sleepers are spaced at 400 mm from centre to center and are of 2.0 m X 250 mm X 250 mm in size.
