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...

The truss is to be analyzed assuming the two loads shown are each 80 kips. By analyzed I mean that reactions at supports are to be determined and the forces (magnitude and sense) acting internally in each member are to be determined. Once forces are known, the members are to be "designed" -that is, the cross sectional area required determined-based on the following...

l Truss A truss is a structure that typically consists of 1. All straight members 2. connected together with pin joints 3. connected only at the ends of the members 4. and all external forces (loads&reactions) must be applied only at the joints. The weights of the members may be neglected. The basic building block of a truss is a triangle. Large...
