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

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

5) A 24 ft axially loaded W12x96 column that has the bracing and end support conditions shown in the figure. Determine pcPn using the AISC Specification and Fy=50 ksi. 10 ft 24 ft 14 ft -r axis-y axis

A W12x96 column bears on a 24-in x 24-in concrete pedestal. The minimum concrete compressive strength is fc' = 3 ksi, and the base plate yield stress is Fy = 36 ksi. Determine the base plate plan dimensions and thickness for given required strength (Pu = 683 kips).

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.

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: 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

1) A W12x96 section consisting of 50 ksi steel is used for a 14 ft. long beam-column in a braced frame. The member support service load PDL-80 k, PLL-120 k, MDX-60 ft-k, MLX-12-ft kips, MDY-20 ft-kips and MuY - 35 ft-k. These members are applied at both ends of the column so as to put it in single curvature about both axes.

6) A W12x96 Fy = 50 ksi 12 ft long column in a braced frame is subject to factored loads of Pu=600 k, Mux = 80 k*ft, and Muy=0k*ft. 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. (15 pts)
