N2 - Purpose –
This study aims to reveal more information and understanding on performance and
failure mechanisms of high strength steel endplate connections after fire. Design/methodology/approach
– An experimental and numerical study on seven endplate connections after
cooling down from fire temperature of 550°C has been carried out and reported
herein. Moreover, the provisions of European design standard for steel
structures, Eurocode 3, were validated with test results of high strength steel
endplate connections. Findings – In endplate connections, a proper design using
a thinner high strength steel endplate can achieve the same failure mode,
similar residual load bearing capacity and comparable or even higher rotation
capacity after cooling down from fire. It is found that high strength steel
endplate connection can regain more than 90 per cent of its original load
bearing capacity after cooling down from fire temperature of 550°C. Originality/value
– The post-fire performance of high strength steel endplate connection has been
reported. The accuracy of Eurocode 3 for endplate connections is validated
against test results. Keywords Numerical study, Experimental study, High
strength steel, After fire, Endplate connection
