Arches in Architecture

An arch is a curved structure that is used to support the weight of a building or other structure. Arches have been used in architecture for thousands of years and are known for their strength and stability.

Types of Arches

There are several different types of arches, including:

• Round arch: This is the most common type of arch, with a semicircular shape.
• Pointed arch: Also known as a Gothic arch, this type has a pointed top.
• Flat arch: This type has a slight curve and is often used in bridges.
• Parabolic arch: This type has a very pronounced curve and is often used in modern architecture.

Forces at Work

Arches work by distributing the weight of the structure above them outward and downward, into the supporting columns or walls. This means that the outward thrust of the arch must be counteracted by the strength of the surrounding structure.
