• Layout optimization
• Trusses
• Close upper bounds

In a recent work, Sok and Rozvany have shown a family of benchmark solutions for the two load problem, probably the optimal one. Taking into account that the difference in cost from previously known solutions was small, we have looked for a simpler albeit sub-optimal family of solutions. As a result, we have obtained three sub-optimal families, including one with a simple circular arc. The three families are compared with the benchmarks, and we have found that all three are of practical interest, because they increase the cost only by a small amount in spite of their simplicity.
