What is Structural Engineering & Structural Analysis & Why It Matters
Structural analysis is the systematic assessment of how structures behave under various forces and conditions. A key part of structural analysis is verifying how forces travel through the structure, ensuring a continuous and stable load path from the roof and floors down to the foundation. Structural analysis often involves calculating the resultant force from multiple loads acting on a structure to determine the total effect on structural elements. Proper analysis ensures:
- Safety and stability
- Compliance with building codes
- Optimized material use and project cost efficiency
- Prevention of long-term structural failures
Structural analysis is essential for achieving optimal performance and ensuring structures can withstand real world conditions.
Whether it’s a wood-frame home or a multi-story commercial building, structural analysis guarantees your project is safe, efficient, and durable.
Types of Structural Loads
In structural engineering, understanding the different types of structural loads is essential for ensuring the safety, stability, and longevity of any building or structure. Structural loads are the forces, pressures, or weights that act upon structural members and components, and they play a critical role in the design and analysis process. Structural engineers must carefully evaluate these loads to prevent structural failure and to comply with building codes such as National Building Code of Canada (NBC).
Dead loads are the constant, static forces resulting from the self weight of the structure itself and all permanent building materials and components. This includes the weight of walls, beams, columns, floors, roofs, and any permanently installed equipment. The unit weight of materials like steel, concrete, and masonry is a key factor in determining the dead load for each structural member.
Live loads refer to the variable or transient forces that a structure experiences during its use. These include the weight of occupants, furniture, movable equipment, vehicles, and other imposed loads that can change over time. For example, floor live loads in an office building will differ from those in a residential home, and structural engineers must account for these differences in their calculations.
Wind loads are the forces exerted by wind pressure on the exterior surfaces of buildings and other structures. Wind loads can be especially significant in open terrain, coastal regions, or areas with high wind speeds. The design process must consider factors such as building height, wind speed, external pressure, and the shape and orientation of the structure to ensure that all structural elements can safely resist wind-induced forces.
Snow loads are the result of accumulated snow on roofs and other horizontal surfaces. The magnitude of the snow load depends on the ground snow load for the region, the roof slope, and whether the roof is flat or sloped. In areas with heavy snowfall, snow loads can be a significant design consideration, particularly for flat roofs and large-span structures.
Earthquake loads (or seismic loads) are dynamic forces generated by ground motion during an earthquake. These loads can cause significant stress and movement within a structure, and the design must account for factors such as the seismic base shear, the importance factor (which reflects the potential risk to human life and critical facilities like police stations), and the overall structural system. Properly designed load combinations help ensure that structures can withstand earthquake loads without catastrophic failure.
Other loads include environmental loads such as rain loads and ice loads, which can add additional weight or pressure to roofs and other structural components. For example, rain loads are particularly important for flat roofs with limited drainage, while ice loads may be a concern in colder climates where ice accumulation is possible.
To ensure structural integrity, structural engineers use load combinations—the process of combining different types of loads (such as dead loads, live loads, wind loads, and snow loads) to determine the most critical loading scenarios. Load factors are applied to account for uncertainties in the magnitude and distribution of loads, providing a margin of safety in the structural design.
The National Building Code of Canada and other building codes provide detailed guidelines for determining specified loads, load combinations, and load factors. Structural engineers must also consider various factors such as the intended use of the building, the type and spacing of structural members, the connections between components, and the properties of building materials.
By thoroughly analyzing all relevant structural loads—including dead loads, live loads, wind loads, snow loads, earthquake loads, and other environmental loads—structural engineers can design buildings and structures that are safe, efficient, and compliant with all applicable codes and standards. This comprehensive approach helps prevent structural failure, protects human life, and ensures the long-term performance of the built environment.

Example: In one educational facility, we performed advanced load distribution analysis to optimize beam placement, accounting for the given load, distributed loads, and external forces, and reducing material use while ensuring safety through careful evaluation of material properties determined by analytical methods.
Finite Element Analysis (FEA) for Complex Projects
- Advanced simulations of structural response to applied force and stress
- Used for unique or unconventional designs, such as cantilevered structures, multi-story steel frameworks, or machinery support systems
- Predicts behavior under dynamic, seismic, or environmental loads
- Crucial for projects where standard calculations are insufficient or precision engineering is required
The finite element method (FEM) is a powerful numerical method that divides the whole domain of a physical system into finite elements—smaller elements or individual elements—creating a discrete system with a finite number of unknowns. This approach enables the analysis of complex geometries and physical phenomena that are difficult to solve analytically. FEA software utilizes advanced numerical techniques, such as mesh refinement and the use of basis functions and shape functions, to obtain approximate solutions to partial differential equations and differential equations that describe mathematical models of real-world systems. Modal analysis and static analysis are performed to assess vibrational and steady-state behaviors, respectively. The formulation and solution process relies on the weak form, appropriate boundary conditions, and principles like potential energy. FEA can simulate heat transfer, fluid flow, and pressure distribution, supporting practical applications such as virtual prototyping and complex simulations. Analytical solutions are used to validate FEA results, and mesh refinement with smaller elements improves the accuracy of the approximate solution. Strain energy and virtual work are fundamental concepts in structural analysis using FEA, ensuring reliable predictions for engineering design.
FEA allows us to visualize stress distribution and ensure maximum safety and material efficiency.
