Task No. 2: Load bearing system

Objectives:

• 2 variants of structural system (scale 1:100)

• description of systems, materials and technology

• advantages and disadvantages of particular variants

Task No. 2: Load bearing system

LBS is composed of vertical and horizontal structures:

• vertical structures: bearing walls, bearing columns

• horiznotnal structures: floors, roofs

Vertical structures and typical dimensions(for the first sketches when thinking about future building)

External bearing walls – thermal protection needed

• masonry structure

• brick blocks like Porotherm 44 P+D etc. ~ 440 mm

• YTONG Lambda 375 mm

• thinner masonry structures (250 – 300 mm) + external

thermal insulation (80 – 150 mm)

• reinforced concrete walls (150 – 200 mm) + external thermal

insulation (80-150 mm)

• prefab panels including in-built thermal insulation – wooden,

prefab reinforced concrete etc... 250 – 400 mm

Vertical structures and typical dimensions(for the first sketches when thinking about future building)

Internal bearing walls

• masonry structure

• brick blocks like Porotherm 30 P+D etc. ~ 300 mm, 24 P+D

240 mm

• YTONG about 300 mm

• reinforced concrete walls 150 – 200 mm

• prefab panels – wooden, prefab reinforced concrete etc...150 –

250 mm

Vertical structures and typical dimensions(for the first sketches whne thinking about future building)

Bearing columns

• reinforced concrete (precasted, built in-situ) 300x300 mm

• steel 300x300 mm

• timber – used in smaller buildings up to 4 storey builidngs

• masonry – not so often
