Bridges presentation
Brenta in the Veneto region in northern Italy. Destroyed several times, it has been carefully rebuilt
faithfully following the original layout and exists today as the only example of one of Palladio's
bridges.
The truss form, derived from the Romans, represents one of the Renaissance's most significant
contributions to bridge building. Renaissance engineers also devised daring innovation in arch forms
- the segmental, elliptical, and multi-centred.
The Hungarian, Janos Veranscics, reviewed these and other achievements in the structural arts at the
end of the Renaissance in Machinae Novae, published in 1617. Several concepts that later became
standard bridge practice first were illustrated in this volume: the tied arch, the Pauli or lenticular
truss (in wood), the all-metal truss (in cast brass), a portable, metal chain-link suspension bridge, the
use of metal in reinforcing wooden bridges, and the eye-bar tension member (again in brass).
