- A bolted connection of the general form shown inFigure 11.6 is to be used to transmit a tension force of 75 kips dead load and100 kips live load by using 7∕8-in. A325 bolts and plates of A992 steel withFy = 50 ksi and Fu = 58 ksi. The outer plates are to be 8 in. wide and thecenter plate is to be 12 in. wide. Find the required thicknesses of the platesand the number of bolts needed if the bolts are placed in two rows. Sketchthe final layout of the connection.Calculate the maximum tensile load, Ta or Tu of the connection shown in Figure 7. Theconnection consists of two 3/8" plates fastened to each side of one 13/16" plate.Assume 7/8" diameter bolts and standard punched holes. Use A36 steel. The plate is 13” wide. Note: Be sure to check all failure modes; bolt failure modes, and member failure modes(including block shear)Hhello, Thanks a lot for your help, please I have the following points: 1-Is it allowed to use Fult=65 ksi? 2-Why we consider Wt section? this procedure as I understand is applied when the connection is to flange. 3-The net area estimated is only for one bolt, i believe An=11.80-(4*7/8*0.305)=10.733 inch^2. 4-x bar which I consider is from case 2 only since case 7 will not work, x bar is only Tw/2 value?. U value=1-(0.1525/6.50)=0.977. Could you please advise? Thanks.
- Two steel plate tension members have been connected using 0.72 inch diameter bolts arranged in an equally-spaced 9 by 3 rectangular formation. Both plates have a thickness equal to 1/3 in. Take shear fracture stress as 51.2 ksi, clear distance for each edge bolt as 0.12 in, and the clear distance for the other bolts as 1.072 in. a)Sketch the connection showing all the details and measurements with units. b)Find the maximum allowable service dead load and live load assuming live load is half as much as dead load. Consider ASD.Answer asap for an upvote. Thank you. in the connection shown in the figure,the bolts are 3/4 inch in diameter and A50 steel is used for all components. compute for the nominal block shear strength (kips) of front plateThe truss member shown in the accompanying illustration consists of two C12 x 25s(A36 steel) connected to a 25 mm gusset plate. How many 22 mm A325 bolts (threads excludedfrom shear plane) are required to develop the full design tensile capacity of the member if it isused as a bearing-type connection? Assume U = 0.85. Use ASD method.
- Design a weld connection for an UNP 280×80×9 of S 355 (fy= 355 MPa and fu= 470MPa) steel connected to a 10 mm gusset plate. The guesst plate is S275. Please draw all calculated values on a sketch with full dimensions. D= 335 KNL= 670 KNA C15x40 channel section is bolted to a gusset plate is used to resist a tensile loadPu =313 k. The bolts are 3/4 inch diameter bolts A325 N (Group A, N Type) used insingle shear to resist this load. The bolts are to be symmetric and arranged in 3 rows.1) Determine the number of bolts needed for this connection. Draw a detailshowing how the bolts are arranged and showing spacing and edge distances onthis connection. Assume edge distance Le = 1.75db , use Le to nearest 1/4 in.2) If the connection is to be replaced by a fillet welded connection with transversewelds only along the channel web, determine the required fillet size to thenearest 16th of an inch.Compute the capacity of the connection considering all possible modes of failure. Assume that the determination @ bolt is a design consideration, A490 bolt are used with threads included from shear planes.
- Plz, solve this problem as detail as you can? Steel Structure Design a concentrically loaded bolted connection with the following given information. Also verify your design and draw s sketch showing final layout of the connection. Size and type of bolts: 3/4-in A325 (Group A) bolts in standard-size holes with threads excluded from the shear plane in a bearing-type connection shown in figure 1. Use Fu= 58 ksi and assume edge distances to be 2 in and the distance center-to-center of holes to be 3 in, Assume that deformation at bolt holes is a design consideration. Pu = 345 k using LRFDThe bracket connection shown in Figure must support an eccentric load consisting of 9 kips of dead load and 27 kips of live load. The connection was designed to have two vertical rows of four bolts, but one bolt was inadvertently omitted. If 7⁄8inchdiameter Group A bearingtype bolts are used, is the connection adequate? Assume that the bolt threads are in the plane of shear. Use A36 steel for the bracket, A992 steel for the W6 x 25, and perform the following analyses: (a) elastic analysis, (b) ultimate strength analysis.Design for a tension member based on the followingconditions below: • Tension member: single unequal leg angle bar with a grade of A36 and a length of 6.08m • Service tension load: with a dead-to live load ratio of 878 2:3• 5 bolts per line with 75 mm spacing on center.• Connected to a 10-mm-thick A36 gusset plate A complete sketch showing all necessary information for the said connection is needed.Design this one using ASD method.
