Building Structures 1

#5

Antonín Lupíšek

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

Dimensions - girders

Dimensions – one way slabs

Dimensions – two way slabs

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.
