What are the conditions for the structures?
Centre gravity, Rigidity and Resistance
Centre gravity, Stability and Resistance
Stability, Resistance and Rigidity
All are correct
What is stability?
The ability of a structure to bend
Ability of a structure to stand upright and not fall down.
Ability of a structure to sink
What is resistance?
The ability of a structure to withstand stresses without breaking.
Ability of a structure to expand its base
Ability of a structure to deform
What is rigidity?
The ability of a structure to bend without breaking.
The ability of a structure to bend and break.
When a structure cannot deform
To give stability to a structure we can:
Widen its base
Bury the lower part in the ground and use strong foundations
Centre the weight on the lower part
All are correct
Mark some of the most resistant materials:
steel, stone, coal, cement, wood, plastic, gypsum
steel, stone, cement, wood, plastic
coal, cement, wood, plastic, gypsum
For structures to be stiff and not to deform, three basic aspects must be taken into account:
shape, joints and weight
shape, joints and triangulation
weight, triangulation and materials
What is compression?
When we use thick, often hollow, elements to prevent buckling
When we make the section larger and stress the elements
When we make the width larger and use more material at the top
A structural condition assessment is the process of ----------------------- of observations and data and their systematic use to evaluate and assess the condition of an existing structure.
Stressing
Gathering
Rigidity
Evaluation
What factors does resilience depend on? Please tick the correct options:
Type of material, Amount of material, The time it is
The time it is, The number of workers, The day of the week
Type of material, Amount of material, The shape of the structure
For a structure to be preserved over time, it must be:
Beautiful, sturdy and large
Stable, strong and rigid
Sturdy, tall and with a wide base
To make rigid joints between the parts of a concrete structure, we use
Steel rebar frameworks
Iron bar
wooden bars
To prevent deforming, we can use:
corbelling
triangulares structures
steel rebar frameworks
