structures

structures

1. mass structure

   • these are solid, heavy and very study

2. fame structure

   • these structures are formed by columns and beams

3. truss structure

   • these structures are composed of bars that form triangles

4. suspended structures

   • these are held in place by cables

5. esncial characteristics

   • rigidity
     • it does not change shape when force is applied to it
   • equilibrium
     • when its strucrure remains stationary
   • stability
     • equilibrium if it does not move when a force is applied to it

6. elements that increase th stability

   • stability
   • centre of gravity
     • is the point where the weight of an object is consireded to be concentrated

7. to make structures more rigid , we can add strengthening elements

   • trussing
     • is a metod to do structures more rigid. It eorks because the triangle is the only figure that cannot be theformed
   • brace
     • is a part that positioned diagonaly between two bars to connect them by forming a right angle
   • stay cables
     • are used to helps support the tensile stresses in other component of a structure by distributing the weight to the suports or the terrain where thew are anchored
   • sections
     • the oter strengthening elements that we have already seen are beams and columns
