3) A W12x96 section (A992) is used for a 12 ft long beam-column in a braced frame. The member must support unfactored compression loads PD = 85 k and PL = 125 k and unfactored moments Mpx = 70 ft-k, MLx= 120 ft-k, Mpy= 20 ft-k and Mly = 35 ft-k. The moments are applied at both ends of the column so as to put it in single curvature about both axis.

Question: Determine O.P. for a 24 ft. axially loaded W12x96 column that has bracing and end support conditions as shown in the figure below. Use LRFD Specifications and assume the yield strength of the material, Fy, is 50 ksi. (Answer: 1023.3 k) 10 ft 24 ft 14 ft X-X axis y-y axis

Question: A W12x96 shape is used as a column member in a steel frame structure. The criticallength for strong axis bending is Lcx=50ft while the critical length for weak axis bending isLcy=30ft.Compute the "squashing" load for the column.Compute the slenderness ratio, Lcxrx, for strong axis buckling.Compute the Euler buckling load, Pe, for strong axis

Question: 1.) A W12x96 Fy =50ksi12ft long column in a braced frame is subject to factored loads of Pu =600k, Mux =80k∗f, and Muy - 0k∗f. Assume that the column is bent in single curvature and that the end moments are equal in magnitude at both ends. Using LRFD, determine if this column has adequate strength to support these factored loads.2.)

A W12x96 column is 15 ft long and braced at mid height in the weak axis (make sure to watch the videos in this module to learn how to deal with bracing of one axis). The column carries a service dead load of 140 kip and a service live load of 190 kip.

2. Determine the maximum factored load P, permitted for the beam shown below. The beam is of W12x96 section and ASTM A992 steel. (Hint: The beam is fixed at one end and roller at the other. Use the right case in Table 3-23 for the maximum moment.) P Lateral bracing at …

A 4.5 m, W12x96, 345 MPa steel is being used as a beam-column in a braced frame. It is bent in a single curvature with equal and opposite end moments and is not subjected with intermediate lateral loads. Determine if the section is adequate for the given first-order analysis results PDL = 1335 KN, PLL = 780 KN, and MDL = MLL = 80 KN -m.

Question: calculate the design compressive strength of a W12x96 column that is 12 ft long and braced at the mid height in the weak axis, but not in the strong axis. Use K=1. Fy=36ksi. E=29,000 ksiexpress in kip.FOR ASD
