Introduction ➢ In modern building constructions, the increasing demands of long span floors but with shallow floor depth have led to the development of various composite floor systems. ➢ In conventional composite floor systems, the depth of beam section normally increases with the length that the floor spans over and it results in the steel sections of the ordinary down stand composite beams being heavier and deeper than expected. ➢ The height of the floor is usually about 400mm and the composite beam is at least 600mm
> Composite slim floor systems were developed in the 1990s in the UK to provide floor systems with a minimum constructional depth.The feature is the steel beam contained within the slab depth,resulting in a flat appearance. >Several arrangements of beams and slabs can be used to obtain the structural floor system;however the beam always is contained within the slab depth They have several advantages ①shallow floor depth; ② inherent fire resistance; 3 benefits in terms of cost
➢ Composite slim floor systems were developed in the 1990s in the UK to provide floor systems with a minimum constructional depth. The feature is the steel beam contained within the slab depth, resulting in a flat appearance. ➢ Several arrangements of beams and slabs can be used to obtain the structural floor system; however the beam always is contained within the slab depth . They have several advantages : ① shallow floor depth; ② inherent fire resistance; ③ benefits in terms of cost
