Problem 1. A W30 x 116 beam has the top flange restrained against lateral displacement and rotation and has an unstiffened web. A point load is applied to the top flange at 2m. From the left support. The beam spans 12 m. Use A36 steel with yield strength of Fy = 248 Mpa. a. Compute the maximum value of point load that may be applied without web yielding occurring. b. Compute the maximum value of point load that may be applied without web crippling occurring. Properties of W30 x 116 d = 762 mm K = 41.28 mm bf = 266.7 mm tf = 21.59 mm tw = 14.33 mm

Question

Problem 1. A W30 x 116 beam has
the top flange restrained against
lateral displacement and rotation
and has an unstiffened web. A point
load is applied to the top flange at
2m. From the left support. The beam
spans 12 m. Use A36 steel with yield
strength of Fy = 248 Mpa.

a. Compute the maximum value of point load
that may be applied without web yielding
occurring.


b. Compute the maximum value of point load
that may be applied without web crippling
occurring.


Properties of W30 x 116
d = 762 mm
K = 41.28 mm
bf = 266.7 mm
tf = 21.59 mm
tw = 14.33 mm
