Description
Many old buildings have sound walls but rotten timber floors. Ahmed Shamel Fahmy and co-authors test a replacement floor built from cold-formed steel, thin steel shaped without heat. Their design is a box section: a concrete slab poured on trapezoidal steel decking, two sigma-shaped steel members, a steel plate, and stiffening angles, all joined with self-drilling screws. It is meant to install quickly and cheaply in restoration work.
The team loaded four full specimens to failure and recorded how they bent and strained. The floors proved stiff and strong, reaching full capacity without the thin steel buckling locally. Failure came instead from distortion at the end supports. Hand calculations matched the test results well, and a computer model of the system reproduced its behavior, supporting the design for reuse in old buildings.
