A W14X120 is used as a tension member in atruss. The flanges of the member are connected to a gusset plate by 3/4 inch boltas shown below. Use A36 steel with Fy-36 ksi and Fu=58 ksi Determine the Yielding Capacity of the section based on LRFD (kips) Determine the Tensile Rupture capacity of the section based on LRFD Determine the Demand to Governing Capacity Ratio (based on yielding and rupture only) if the Demand load carried by the section are DL=200 kips LL=400 kips use LRFD Properties and Dimension Ag=35.30 in^2 x = 6.24 in ry= 3.74 in d=14.5 in tf=0.94 in bf=14.7 in tw=0.59 in k=1.54 d=14.5 Y k1=1.5 bf=14.7 tf-0.94 X -tw=0.59 H

The welded frame beam connection consists of the framing angle 100 x 75 x12.5mm and the column W12 x 72. The welds are 9mm fillet welds made with E70 electrodes. All members are A36 steel. 12.5 mm a.) Determine Pu base on the capacity of the welds. Use LRFD design Factors. W 12x72 Angular Section 75 m 18.75 18.75 Angular section Angular section 800

Determine the maximum service load P (ASD) that the connection can resist. Use 27 mm Ø A490-N bolts, and 10 mm A-36 plate and a load P with a slope 1H: 2V. Assume that edge distance and bolt spacing are not critical. ***Note: Lod P is acting at a slope of 1H: 2V

130% v - + 7 Annotate T| Edit Trial expired Unlock Full Version ENGR 263 A A A EXERCISES Eleven sets of illustrations and the corresponding free-body diagrams of building-related beams were provided in Chapter 4 as Exercises 4. I through 4.11. These free-body diagrams constitute exercises that will be used here and again in Chapter 12. Follow these instructions carefully to save time later: (a) On each sheet of engineering paper reserved for analysis, calculate the vertical shear specific to that member at appropriate intervals across the length of the free-body diagram. Be sure to solve for locations where shear passes through zero. (b) On cach sheet of engineering paper containing the tree-body diagram, neatly draw the related shear diagram directly below the associated free-body diagram. The shear diagram should be located in the middle one-third of the page. Reserve the bottom one-third of the sheet for the bending moment diagram introduced in Chap- ter 12. Be sure to show…

An A36 axially loaded 12mm thick tension member is connected to a gusset plate using 5pcs 20mm diameter rivets arranged as shown. Use Fy= 248MPa & Fu=400MPa for the steel plates. Given a=67mm, b=99mm, c=67mm, x=76mm, y=68mm and z=63mm. Considering the green shaded area to be in Block Shear Rupture (BSR), where its nominal block shear strength can be calculated using Rn=0.6FuAnv+UbsFuAnt . Calculate the net area along tension surfaces, Ant in mm2.
