Others 12 Marks
Q.1.Attempt any FIVE of the following.
(10 Marks)
a. List two types of steel sections used as a tension member and show it on the neat
sketches.
b. List two end conditions of column along with their equivalent length.
c. Write B. I. S. specifications for effective flange width of T and L beam.
d. State four categories of stairs from design point of view.
e. State effective span of stairs without stringer beams for two cases with neat sketch.
f. Draw the diagram showing distribution of loading on stairs with open walls, where
spans partly crossing at right angles.
g. List types of columns as per slenderness ratio.
Q.2 Attempt any Three of the following.
(12 Marks)
a) A tension member consists of 2 ISA 100 x100 x 10 mm connected back to back at
same face of gusset plate. Calculate its net area if 20 mm diameter bolts are used for
the connection.
b) A T beam has flange width of 1.5 m and an effective depth of 600 mm. The slab
thickness is 100 mm and the breadth of web is 300 mm. The beam is reinforced on
tension side only with total steel area 4500 mm 2 . Calculate the limiting moment of
resistance, if concrete grade M20 and steel grade Fe415 are used.
c) A circular column 500 mm in diameter is provided with six bars of 20 mm diameter.
Calculate the working load carrying capacity if Fe415 steel and M20 concrete are
used. Check the column for minimum eccentricity if effective length is 3 m.
d) A 4 m high column is effectively held in position at both ends and restrained against
rotation at one end. If the diameter of the column is restricted to 400 mm, calculate the
reinforcement to carry a factored axial load of 1900 kN. Use concrete grade M20 and
steel grade Fe415.
Q.3) Attempt any Two of the following.
(12 Marks)
a) A tension member consists of two angles 75 x 50 x 6 mm which are provided on either
sides of a 10 mm thick gusset plate. 20 mm diameter bolts of grade 4.6 are used in
one row for connecting the member to the gusset plate. Calculate the design tensile
strength of member and number of bolts required to carry design tensile strength.
b) Design a tension member to carry an axial service load of 210 kN. Double angle
section with gusset plate in between is to be used. Bolts of 16 mm diameter and 4.6
grade are to be used. Angle sections are available as per following table:
