The structure shown in Figure 1 is a combination of three frames ABC, CDEFG, and NOPQR, as wellas a simple truss GHIJKLMN. The truss is connected to the two frames with hinges at G and N. Thesupport at A is a fixed support, the support at E is a roller, and that at Q is a pin support. The structureis subjected to: a) a uniformly distributed horizontal load acting over ABCD with intensity 20kN/m(kN/horizontal meter); b) a parabolic distributed load with the maximum intensity of 60 kN/m actingon the member PQ; c) two horizontal concentrated loads 30KN acting at E and L; d) verticalconcentrated loads of 20kN, 40kN, 15kN and 5kN, acting at I, K, O, and R, respectively; and finallye) a counter clockwise couple of 50kN.m acting at B.
