TRAVELING FORMWORK WHEEL SUPPORT DESIGN

Hampton Roads Bridge-Tunnel Expansion (HRBT)

SUMMARY

For the design of connections, the commercial software ROBOT was used.

Well-known formulations and codes have been applied and engineering judgment is based on international experience.

The I-64 Roads Bridge-Tunnel in southeastern Virginia, between the cities of Hampton and Norfolk, has long been one of the most congested corridors of the region. The existing 3.5-mile facility consists of two, 2-lane immersed tube tunnels on artificial islands with trestle bridges to shore. These tunnels opened in 1957 (current westbound lanes) and 1976 (eastbound lanes) and are approximately 7,500 feet long.

The Hampton Roads Bridge-Tunnel (HRBT) Expansion Project will ease this congestion by widening the 4-lane segments of the I-64 corridor in the cities of Hampton and Norfolk.

As part of the Hampton Roads Bridge Tunnel Project, Hampton Roads Connector Partners have asked AZIERTA for a structural calculation of the design of the supports for the wheels of a traveling formwork machine. The base scope of the Project consists of the calculations of the longitudinal beams, W6 and W10 supports, and verification of the stability of the machine and all supports.
