选择 W 形杆件,自重为 30.000 牛/牛, Verify the member strength using both LRFD and ASD.
截面为 ASTM A992 W 18×50 的梁用于跨度和均布活荷载,如图 1 所示。 The member is limited to a maximum nominal depth of 18 inches. The live load deflection is limited to L/360. The beam is simply supported and continuously braced. Verify the available flexural strength of the selected beam, based on LRFD and ASD.
左端支承一个 I 形截面的悬臂梁,图中显示了扭矩荷载。 The aim of this example is to compare the fixed support with the fork support and to investigate the behavior of some representative quantities. Comparison is also made to the solution by means of plates. Small deformations are considered, and the self-weight is neglected. Determine the rotation in the midpoint of the cantilever, and in case of the member entity with warping, determine the values of the primary torsional moment, the secondary torsional moment, and the warping moment both on the left end (point A) and the right end (point B).
