The purpouse of an structure is to give shape , withstand forces , protect , raise , create and cross . We classify structures by their main structural element . These types are mass , trabeated , and vaulted , trussed , laminar . geodesic , cable - stayed or suspension , frame and inflatable . A force is an influence that can a body or change it's movement or produce motion in a body at rest . Stresses are the internal that a body is subjected to when different forces act on it . The basic types of stresses are compression , tension , bending , ans shear . An structure will behave appropriately if it does not ( strenght ) , it does not collapse ( stability ) and it does not deform ( rigidity ) . The of a structure depends on the position of its centre of gravity . Trussing is a method for making weak structures rigid .
