7 Common Types of Structural Systems in Architecture

Table of Contents


In the field of architecture, structural systems play a vital role in ensuring the stability, strength, and functionality of buildings. From ancient civilizations to modern-day structures, architects have employed various types of structural systems to support and distribute loads. In this blog post, we will explore seven common types of structural systems used in architecture, shedding light on their characteristics, applications, and benefits. Whether you’re an architecture enthusiast or a professional in the field, this comprehensive guide will deepen your understanding of these essential building components.

1. Load-Bearing Wall System

The load-bearing wall system is one of the oldest and most straightforward structural systems. It relies on walls to support vertical loads and transfer them to the foundation. We will delve into the design principles, materials used, and examples of buildings that employ this system.

2. Frame System

The frame system, also known as the skeleton or skeletal frame system, involves the use of vertical columns and horizontal beams to create a rigid framework that supports the structure. We will explore different types of frame systems, such as steel frames and reinforced concrete frames, and discuss their advantages and applications.

3. Shell System

The shell system refers to structures where the exterior walls and roof act as load-bearing elements, providing both support and enclosure. This system is commonly used in domes, vaults, and thin-shell concrete structures. We will examine the principles behind shell structures and highlight iconic examples from around the world.

4. Truss System

 Trusses are rigid frameworks made up of interconnected members designed to carry loads over a span. This system is prevalent in bridge construction and large-scale roof structures. We will explore the various types of trusses, including Pratt trusses, Howe trusses, and Warren trusses, and discuss their applications.

5. Cable and Tension System

Cable and tension systems rely on tensioned cables or rods to support loads and create lightweight, visually striking structures. This system is often used in suspension bridges, cable-supported roofs, and other architectural marvels. We will delve into the design principles and engineering considerations behind cable and tension systems.

6. Arch System

Arch systems utilize curved elements to distribute loads in compression, providing stability and strength. From ancient Roman arches to modern arch bridges, this system has stood the test of time. We will explore different types of arches, their construction techniques, and notable architectural examples.

7. Grid System

The grid system, also known as the modular or prefabricated system, involves the use of repetitive modules or units to create a flexible and efficient structural layout. This system offers versatility and ease of construction. We will discuss its applications in both residential and commercial architecture and highlight notable grid-based buildings.


Understanding the various types of structural systems is essential for architects, engineers, and anyone interested in the built environment. Each system has its unique characteristics and applications, allowing architects to design structures that are not only visually appealing but also safe and functional. By exploring the seven common types of structural systems discussed in this blog post, we hope to inspire and expand your knowledge of the fascinating world of architecture.
