choosed a section with much higer z and I since if lb exceed lr
again capacity reduces. so for a safer side i did so
A beam 3m long is simply supported at its ends. The beam is
loaded with a downward vertical load of 200N at a point 2m from the
left support.
USING AMM.
a.) The maximum deflection is located at what distance from the
left support? Answer: 1.63m
b.) Calculate the maximum deflection assuming E = 50 GPa and I =
1x10^6 mm4 Answer 2.9mm
A beam 3m long is simply supported at its ends. The beam is

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

(1) A simply supported steel beam is 30' long and subjected to a
uniform distributed 1.3 kips per foot. What is the minimum required
section modulus for this beam if we do not want its maximum stress
to exceed 50 ksi?
(2) What is the minimum inertia of the beam in the previous
question if we do not want it to deflect more than 1/2" ?
STEEL STRUCTURES
A 20ft long simply supported beam is made of W21X55 with
fy=50ksi. The service distributed loads on the beam are DL=2k/ft
(including self weight), LL=4 k/ft. Show if the beam is adequate
for shear.
This question is referring to a concrete beam with steel rebar
reinforcement,
For a simply supported beam with width 10 inches and depth 14
inches design the steel to resist a maximum moment of 50 kip feet.
span=15 feet. Concrete 4 ksi. steel is 60 ksi.
What are the problems arised in simply supported beam
bridge(any
component of the bridge or steel trusses type) and how to improve
the qualities or the problems arised?
A simply supported beam has a width of 200mm and depth of 400mm
is 4m long. It carries a uniformly distributed load of 20 kN/m over
the whole beam and a point load of 40 kN at the center of the beam.
Compute the maximum deflection if the maximum slope produced in the
beam is 2× ??-3 radian.
Determine the required shear reinforcing for a simply supported
concrete beam 7 meters long with a cross section of 500 millimeters
in depth and a width of 380 millimeters. Use fc = 35 MPa fy = 400
MPa. The longitudinal steel uses one row of 25M bars. The specific
live load is 29 kKn/m. The beam is not exposed.
Consider a W30x99 beam (Fy = 60 ksi) that is simply supported,
30 ft. long, and subjected to a point load
at the midspan. The point service load consists of 60% live load
and 40% dead load. Lateral supports exist
at the ends only. Design code to comply with: 2016 AISC LRFD.
