Floor Structures
• monolithic reinforced concrete
• monolithic RC with „lost formwork“
• prefabricated reinforced concrete
• composite reinforced concrete
formwork drawing = homework #3
drawing of layout of precasted structure
= homework #4
Homework No. 3formwork drawing (scale 1:50)
• it is the view into finished formwork
before pouring concrete in it
• represents a real shape of a concrete
structure with basic dimensions

What can we find out from FD?
• location of bearing elements
• shapes and dimensions of future floor structures
• locations, dimensions and shapes of hatchways
• type of construction (element type ...)
• specification of used material (concerete type)
Line types
• visible lines and edges – thin full line
• invisible (hidden under formwork) – thin dashed line
• bearing structures (walls&columns) outlines – thick full
• hatchways or
Elements signs
Each element (wall, column, floor slab ...) has its own sign
made from big letter and number i.e. C1, W3 etc.
• vertical elements’ signs are in a square: C1 ... column no. 1
• horizontal elements’ signs are in a circle: S2 ... slab no. 2
• the area of slabs is signed with a diagonal crossing
• the element reinforcement orientation is symbolised by
arrows

Your homework
Choose one of your bearing system schemes
and for its part (about 12 x 10 m) make a
formwork drawing (scale 1:50), including
dimensions pre-design of floor girders and
slabs.
