Topology Optimisation of Warren Trusses

In this study we have considered 9 Warren truss each with a distinct span and height and each truss was subjected to 9 loading conditions and 81 cases were formulated. Each case was optimized to get a target stress of 100 MPa in each member and the steel Take Off was calculated. This steel take off was compared with other span and height combinations of the Warren truss for the same loading condition and the mass used of the steel was compared. In this way optimisation results in the efficient utilization of material and hence reducing the cost of the structure.
