Performance study of composite metal decks With openings under combined sustained loading and fire

Abstract

This paper examines the load-bearing behavior of metal deck composite decks with openings under sustained loads and fire. For concrete used to be poured over metal decks, metal decks are divided into 2 groups: concrete using general aggregate and concrete using aggregate from digested concrete. which has a
positive effect on the use of alternative materials Both in terms of strength properties of concrete mix from aggregate from concrete rubble depends on the strength of concrete crumbs. Payload sustained and fire by measuring between time and temperature and deflection with the load remaining. which
factors affect the fire resistance rate Consists of concrete properties including type and properties of steel floors, steel beams, anchoring and composite action. Each fire has a temperature of 600 °C - 1000°C. Indoor steel can be melted under high temperature. 1500°C
