STRUCTURES

STRUCTURES

1. TYPES OF STRUCTURES

   • mass,frame,truss,suspended
   • EXAMPLES:
     • walls,dams,caluums...

2. elements that increase rigidity

   • trussing
   • brance
     • stay cables
       • sections
         • closed section: square section , triangular section ,circular section
         • open section: shaped,

3. CONDITIONS FOR STRONG STRUCTURES

   • MATERIAL:
     • rigid,elastic and plastic
   • behaviour when force is applied:
     • does not form
       • deforms but then retumsto its original shape
         • deforms and stays deformed

4. TYPES OF STRESS

   • bending
   • torsion
   • shear
   • comprenssion
   • tension
