Abstract

A novel active self-strengthening approach for structural steel members in fire is investigated experimentally. The proposed approach employs the shape memory effect phenomenon in NiTi shape memory alloys. By exposing the composite steel-NiTi member to high temperatures, large recovery stresses are generated from the shape memory alloy and counteract the actions produced from the applied loads. A series of high temperature tests for steel and steel-NiTi composite beams were conducted to demonstrate the validity of the approach proposed in this paper.
