This paper aims at the automatic design and cost minimization of reinforced concrete vaults used in road construction. This paper presents three heuristic optimization methods: the multi-start global best descent local search (MGB), the meta-simulated annealing (SA) and the meta-threshold acceptance (TA).

need for traditional formwork. The concrete can be poured directly onto a tile-vaulted formwork to form a composite structure. This paper presents a technique for the construction of single-curvature shells consisting of a composite structure combining tile vaulting and reinforced concrete. A method for the design of these composite vaults and

Manufacturing Plant. Oldcastle concrete electrical vaults, also referred to as splice boxes and switchgear vaults, are the industry's leading product choice to protect and provide access to electrical cables and transformers, and are a preferred alternative to running electrical power cables above the ground and across utility poles.

In addition, there is one modular concrete vault design in the United States: the Fort St. Vrain, Colorado, Independent Spent Fuel Storage Installation, which stores spent fuel from a high-temperature gas-cooled reactor. This reactor operated until 1989 and is now decommissioned. Because this is a one-of-a-kind facility, and the time available.

The design of reinforced concrete (RC) vaults is a key aspect of the construction of road, railway and hydraulic artificial tunnels. Vault tunnels are particularly appropriate when the tunnel length is more than several hundred meters and when the earth cover is more than several meters. This is so since the cost of the vault formwork equipment.
