3. A steel truss bridge in the Gallatin National Forest is composed of two identical trusses. If one of the trusses is supported by a pin joint at A and a roller joint at H and the loads are as shown, determine the forces in members AB, AC, DF, EF and EG and specify whether these members are in tension or compression.

Designing a truss bridge This lab involves the design of a truss bridge, which is a Pratt truss and should be designed to handle the loads shown in Fig- ure l (1 kip = 1000 lb). Note that the loads are the same on each of the two trusses for the bridge, so what is in Figure 1 is only half the loading on the bridge. Your job is to develop an optimal design for the bridge, Figure 1. Schematic...
pz explain. 6-58. Draw the influence line for the force in member CF, and then determine the maximum force (tension or compression) that can be developed in this member due to a uniform live load of 800 lb/ft which is transmitted to the truss along the bottom cord. AL 10 ft 10ft--.--10 ft 10 ft

a. Specify the type of compound truss shown in Figure 2. Assume all members are pin connected. The truss is pin supported at A and roller supported at F. Investigate the determinacy and stability of the truss Using the method of section, determine the force in member CD. State if the member is in b. c. tension or compression d. Using the method of joint, determine the force in members JK and JN. State if the members are in tension...

(a) Warren truss (b) Howe truss (c) Pratt truss (d) Baltimore truss (e) Parker truss Figure 2: Truss Types (Nielson Text) The truss bridge has the following properties/characteristics: 1. Span length (bottom chord): 168 ft 2. 14 panels (12 ft length per panel) 3. All diagonals are 45 degrees 4. Simple truss (all members are pin-connected and loads are only applied at the joints) 5. Simply-supported (pin at one end, roller at the other) 6. 13 ft width between trusses...
The truss shown is used to support the floor deck. The uniform load on the deck is 3k/ft. This load is transferred from the deck to the floor beams which rest on the top joints of the truss Determine the force in cach member of the truss, and state if the members are in tension or compression Assume all members are pin connected 16 I1 12 m 12 1 12 n
