Consider a member with a rectangular cross section subjected to
a compressive load P which is delivered through a rigid block on
the upper end of the member as illustrated below. The upper end of
the member is free to rotate about both axis directions, but is
constrained from lateral deflection in one of the directions by the
rigid guide plates illustrated. The lower end is hinged and this
allows rotations about one axis direction only. Assume the member
is...
A horizontal beam AB is pin-supported at the end A and carries a uniformly distributed load with intensity 20 kN/m and a concentrated load F as shown in the figure. The beam is also supported at C by a pinned-end column: the column is restrained laterally at mid-height in the plane of the figure but it is free to deflect perpendicular to the plane of the figure. Assume the column may buckle in any direction. The column is a solid...

4. Steel members AB and AC have Cross-section with the dimensions shown the rectangular 29.0 X 103 ksi; ơys 50 ksi. a) Determine which member (AC or AB) is a candidate 1.5 in. С 1.5 in. for buckling: and then determine the maximum load P th e frame can support such that buckling does not 2.5 in occur with respect to the y-axis, nor with respect to the z-axis. Treat the end conditions as pinned at both ends for...
A steel I-section beam, simply supported at its two ends, is
subjected to a uniformly distributed load q (vertically downward)
over its central segment having a length of 2 m as shown in the
figure. It also shows the type of restraints (F/P/L) against
lateral torsional buckling of the beam at its four sections. The
section at the left end of the beam has only the lateral rotational
restraint. The load is causing bending of the beam about x-x (major...
A crane which has a 30m long jib inclined at 70degree to the
horizontal is used to lift a load W at the free end as shown in
Fig.1. The job is secured at the top end by a cable and pinned at
the bottom end to the base such that only in-plane displacement is
allowed (i.e consider I about axis zz). It has a hollow rectangular
cross-section with a depth of 500mm, a width of 250mm and a wall...
A 9 m tall atrium is to be constructed in a commercial development. You are required to check the ability of a Grade 300 310UC96.8 to be used as one of the corner columns. The factored ultimate axial load, N* , is 1100 kN. This load includes the factored self-weight of the member. The column is pinned at both ends about the major and minor axes such that the buckling length is 9,000 mm (9 m). The column is also...
Question 1 The stepped flat bar has a constant thickness of 8.0 mm. It carries three concentrated loads as shown. Let P 200 N, L 180 mm, L, = 80 mm, and Ls 40 mm. Compute the maximum stress due to bending and state where it occurs.
