The Iron Skeleton
Discover how embedding steel turned brittle stone into a soaring modern titan.
- The Weakness
Brittle by Nature
Traditional concrete handles crushing weight well but snaps easily when pulled or bent. This lack of tensile strength limited it to arches and short spans.
- Material Hybrid
A Perfect Marriage
Steel reinforcement, or 'rebar,' provides the pull-strength concrete lacks. Together, they form a composite material stronger than the sum of its parts.
- Early Origin
The Gardener's Pot
