Select simply supported timber beams (S4S) for the following
uniformly distributed line loads and spans. deflection is not to
exceed span/240. douglas fir, 200 lb/ft., 24ft span.
Deflection tests were conducted on a steel joist and a
timber joist both simply supported over a span of 5 m and carrying
a point load of 45 kN at distance of ‘a’ from left support. Maximum
deflection was observed at a position 2.4 m from the left support
for steel joist and 1.85 m from the left support for steel joist.
Calculate and compare the results for maximum deflection, slope at
both ends and deflection under the load for...

A simply supported beam of 10m span carries a uniformly
distributed load of 50kN/m spread over 5m from the left support and
a 5kN concentrated load on its center . Its base is 250mm while
deep is 500mm. Calculate the maximum deflection in mm. E = 2.0x10^5
N/mm2. Use the area moment method
A simply supported reinforced concrete beam with uniformly
distributed load of 10 kN/m has a span of 6.0 metres. The beam
cross-section is 225 mm breadth by 300 mm depth. Sketch and design
the beam. Make necessary and realistic assumptions where
applicable
A simply supported beam spans 35ft and carries a simply
distrusted dead load of 0.2kip/ft including the beam self-weight
and live load of 0.8kip/ft. Determine the minimum required plastic
section modulus and select the lightest-weight W-shape to carry the
moment. Assume full lateral support and A992 steel. Design by (a)
LRFD and (b) ASD
Compare the bending moment diagrams of the indeterminate and
simply supported beams. What are the advantages of using
indeterminate beams? Why are thereactions different from those of
the simply suppored beam with similar loading
A 6-m span simply supported beam carries a uniformly distributed
ultimate load of 70 kN/m. The dimensions of the beam section are b
= 300 mm, d = 700 mm. The beam is reinforced with bars of 25-mm
diameter in one row. f’c = 25 MPa, and Fy = 420 MPa. Use
# 10 U-shaped stirrups. Neglect the column width. The stirrup

Use A992 and select a W shape for the following beam:
- Simply supported with a span length of 30 ft
- Braced at the ends of the beam only
- Uniform dead load of .75 kips
- A 34 kip point load at midspan
Use ASD
