Unlike that of the fixed arch, the pinned base can rotate,[12] thus allowing the structure to move freely and compensate for the thermal expansion and contraction that changes in outdoor temperature cause. So, it looks unattractive. It may be either isosceles or equilateral. The center stone at the top of the arch is called the keystone, and it is the piece that locks the arch in its shape and forces the compression of stress.

The Curves surface creates 2 Center Points. This is called compressive stress, because the pressure of the weight is compressed by the shape of the arch. During this period new Roman buildings were designed and constructed such as the triumphal arches, aqueducts, and basilicas. The Rock brick arches are generally wedged in form. The Flat arch is normally utilized for the construction of light-load structures. [10], The most common kinds of true arch are the fixed arch, the two-hinged arch, and the three-hinged arch.

During construction of an arch, the voussoirs require support from below until the keystone has been set in place; this support usually takes the form of temporary wooden centring. The techniques included indesigningandconstructingarches have since been acquired into several otherstructural forms, containingvaults,arcades, andbridges.
