CREATING THE MODEL: PRIMARY STRUCTURES: -­‐ Horizontal: Beams, concrete slab, lintels -­‐ Ver5cal: exis5ng load bearing walls

SECONDARY STRUCTURES: -­‐ Horizontal: colorbond cladding, 5mber flooring, plasterboard ceiling lining, skylights -­‐ Ver5cal: external zinc wall cladding and colorbond, automa5c doors, windows, balusters along ramp

CREATING THE MODEL:

TIMBER WORKSHOP ACTIVITY: GROUP 1:

WEIGHT: 160KG DEFLECTION: 35MM

THE PRESSURE STARTED TO CREATE A TWIST

GROUP 2:

WEIGHT: 250KG DEFLECTION: 50MM

SIMILAR TO THE PREVIOUS GROUP

ONTO THE VERTICAL STRUCTURES,

THE VERTICAL STRUCTURES STARTED TO

THIS IS DUE TO THE COMPRESSION FORCES

CHANGE DUE TO PRESSURE OF THE COMPRESSION FORCES ON THE TOP OF THE STRUCTURE AND THE TENSILE FORCES ON THE BOTTOM END

ON THE TOP OF THE STRUCTURE AND THE TENSILE FORCES ON THE BOTTOM END

TIMBER WORKSHOP ACTIVITY: GROUP 3:

WEIGHT: 590KG DEFLECTION: 55MM

DUE TO THE WAY THE BEAMS WERE STACKED

GROUP 4 (MY GROUP):

WEIGHT: 300KG DEFLECTION: 95MM

WE CREATED AN I BEAM FOR OUR DESIGN. TO JOIN THE BEAMS TOGETHER WE ADDED SCREWS TO THE TOP END AND TO BOTTOM. THE SPACING BETWEEN EACH SCREW ON TOP WAS 20CM AND WE HAD 6 SCREWS. ON THE BOTTOM END WE

THIS DESIGN WITHSTOOD THE MOST WEIGHT

ONLY HAD 4 SCREWS. THIS WAS DONE TO

THE SIDE BOARDS ADDED SUPPORT

CREATE AN EFFICIENT STRUCTURE THAT RESPONDS TO BOTH TENSILE AND COMPRESSION

FORCES AND DOESN'T’T CAUSE CRACKS
