Arches in Architecture

Arches are structures that are commonly used in architecture to provide support for buildings and other structures. They have been used for thousands of years and are known for their strength and ability to distribute weight effectively. There are several different types of arches, each with its own unique characteristics and applications.

Types of Arches

There are several different types of arches, including:

• Round arch: This is the most common type of arch, with a semi-circular shape. It is used in a wide variety of architectural styles.
• Pointed arch: Also known as a Gothic arch, this type of arch has a pointed top. It is often used in Gothic architecture and provides a more vertical profile than a round arch.
• Parabolic arch: This type of arch has a curved shape that is defined by a mathematical parabola. It is often used in bridges and other structures that require a long, unsupported span.
• Elliptical arch: This type of arch has an elliptical shape and is often used in Baroque and Neoclassical architecture.

Forces at Work

Arches are able to support heavy loads because of the way they distribute forces. When a load is placed on top of an arch, the weight is transferred outward along the curve of the arch, and then downward to the supports on either side. This effectively disperses the force of the load and prevents the arch from collapsing under the weight. This distribution of force is what gives arches their strength and stability.
