Model null for wind tunnel test of diagonal built bridge aerial

摘要

PURPOSE: To provide a wind-tunnel testing model in the bridged state of a cable stayed bridge, which can simulate the vibrating characteristic and the shape characteristic of a bridging diagonal bent model as those of a real structure and therefore has the high model testing accuracy for wind resisting stability. ;CONSTITUTION: A bridge-model type rigid rod 1 has the rigidity similar to a bridge. The external-shape material of a bridge model covers the bridge-model type rigid rod l and has the shape similar to a bridge. The rigidity of the external-shape material is almost negligible. A diagonal bent model rigid rod 2 has the rigidity similar to the diagonal bent part of the bridge and can be attached to the bridge-model type rigid rod 1. The external-shape material of a diagonal bent model covers the diagonal bent model rigid rod 2 and has the shape similar to the diagonal bent part. The rigidity of the external-shape material is almost negligible.;COPYRIGHT: (C)1993,JPO&Japio
