Description
A draped arch is a type of arch that has two inverted circles at the corners and a flat top. It is typically made of stone or brick, and it is often used as a decorative element in buildings. Draped arches can be found in a variety of architectural styles, including Romanesque, Gothic, and Renaissance.

Dimensions & Sizes
Draped Arches have typical spans between 4’-12’ (1.22-3.66 m) and arch rises of 16.1”-48” (41-122 cm). Arches are commonly paired with wall depths of 8”-16” (20.3-40.6 cm) and a course depth between of 4”-16” (10.2-40.6 cm).

What is the strongest shape for an arch?
The catenary arch is considered the strongest arch shape due to its ability to optimally distribute weight and withstand loads. Catenary arches mirror the natural curve created by a hanging chain or rope, resembling an inverted parabola. This unique shape ensures that only compressive forces are present, eliminating tension forces in the arch. Consequently, catenary arches efficiently support their own weight and external loads, making them ideal for applications requiring maximum strength and stability.
What are the forces on an arch?
Forces on an arch involve compression, tension, and lateral forces. Compression is the primary force acting on an arch, pushing the voussoirs together, while the keystone redistributes the weight to the abutments. Tension occurs when the arch tries to spread apart but is restrained by the abutments, which resist the horizontal thrust. Lateral forces can result from factors like wind or seismic events, pushing the arch sideways. The arch's curvature and abutments counteract these forces, maintaining stability and balance.
Why aren't arches more common in architecture?
While arches are strong and aesthetically pleasing, they aren't always the most practical choice in modern architecture. Advancements in materials, such as steel and reinforced concrete, allow for more flexible designs and larger spans without arches. Additionally, constructing arches requires skilled labor and precise calculations, making them more time-consuming and expensive than other options.

What is the most common column type used in construction today?
The most common column type today is the reinforced concrete column, widely used in modern construction. Its popularity is due to the excellent strength, durability, and versatility it offers. Reinforced concrete columns combine the compressive strength of concrete with the tensile strength of steel reinforcement bars (rebar), providing reliable support in various building types, from residential to commercial and industrial structures. Additionally, these columns can be easily molded into different shapes and sizes, allowing for greater design flexibility and cost-effectiveness.
What are the different tparts of a column?
A column typically consists of three main parts: the base, the shaft, and the capital. The base supports the column and distributes the load to the foundation, often featuring a decorative design. The shaft is the elongated vertical section, which can be fluted or smooth, and varies in thickness and tapering depending on the column style. The capital is the topmost part of the column, providing a transition to the supported structure, such as a beam or an architrave, and often features intricate detailing or ornamentation.
Why were columns ornately decorated in the past?
Columns were ornately decorated in the past as a reflection of cultural and artistic values. They conveyed a sense of grandeur, elegance, and sophistication, reflecting the social status and power of the building's owner. Ornamentation also showcased the craftsmanship and creativity of the artisans who crafted the columns, often depicting mythological or historical scenes or patterns. Columns played a significant role in defining the architectural style and conveying symbolic meaning through their decorative elements.

What are the tallest walls in the world?
As of September 2021, the Great Wall of China is often considered the longest, but not the tallest. The tallest walls are typically retaining structures, such as the Diga del Vajont in Italy, which stands at 262 meters (860 ft). For inhabited structures, the Ryugyong Hotel in North Korea stands as a wall-like skyscraper at 330 meters (1,080 ft). The Israeli West Bank barrier is one of the tallest security walls, reaching heights of 8 meters (26 ft) in places.
What are the different types of walls used today?
Walls are versatile structures that can be classified into various types based on their function and construction. Load-bearing walls are integral to a building's structure, supporting the weight above them, while partition walls are used to divide spaces without bearing any load. Shear walls are crucial in providing lateral support to buildings, particularly in earthquake-prone areas. Retaining walls are engineered to hold back earth and maintain different levels of soil. Boundary walls define property lines and offer security. Additionally, cavity walls consist of two parallel walls with an airspace in between for insulation, and veneer walls are non-structural, providing a decorative surface.
How will walls change in the future?
In the future, walls are likely to become more adaptive and multifunctional. Smart walls with integrated technology could regulate temperature, lighting, and even display information or images. Modular and movable walls may facilitate adaptable living spaces. The use of sustainable materials like rammed earth or recycled plastics could be prevalent. Transparent solar panels might be integrated into walls for energy generation. Additionally, advances in 3D printing technology could revolutionize how walls are constructed, making it faster and more cost-effective.
