The　research　focused　on　the　design　of　a　curved　shell-supported　footbridge　using　a　form-finding　algorithm　and　genetic　optimization.　The　bridge　was　shaped　through　a　parametric　design　code,　which　also　allows　optimization　based　on　finite　element　structural　analysis.　The　constrained　optimization　involved　a　mono-objective　approach　aided　by　penalty　functions　to　control　the　maximum　tension　utilization　of　the　concrete　material.　The　objective　was　to　find　the　optimal　bridge　shape　in　terms　of　minimizing　displacement　under　vertical　and　horizontal　loads,　with　both　the　topological　optimization　of　the　positions　of　the　bridge　supports　and　the　optimization　of　the　control　points　of　the　Bezier　curve　describing　the　form　of　the　curved　deck　as　key　parameters.　The　results　provide　insights　into　effective　techniques　for　optimizing　the　design　of　curved　shell-supported　footbridges　subjected　to　earthquake　loads.　©　2024,　The　Author(s),　under　exclusive　license　to　Springer　Nature　Switzerland　AG.
