Structural engineering
Structural engineering is a specialized branch of civil engineering focused on designing and constructing buildings and structures that are safe, strong, and durable. Structural engineers apply principles from various disciplines, particularly physics and mathematics, to ensure that structures can withstand external forces such as weight, weather, and seismic activity. They collaborate closely with architects, general contractors, and other engineers throughout the planning and building processes, emphasizing the structural integrity of projects.
These engineers play distinct roles, with responsibilities ranging from overseeing the overall design to addressing specific elements like columns, walls, and frameworks. The role of a structural engineer differs from that of an architect, who primarily focuses on aesthetics and usability. Structural engineers must also be well-versed in local and national building codes to ensure compliance and safety.
In addition to designing new structures, structural engineers are involved in renovations and repairs, assessing the safety of buildings after incidents like fires or earthquakes. Their expertise is vital in creating a built environment that is not only functional but also enduring and resilient to various challenges.

Structural engineering
Structural engineering is a science in which people help create buildings and structures that are strong, sturdy, safe, and long-lasting. Structural engineers have to use knowledge from several different disciplines, such as physics and math, to do their job. To plan and build, structural engineers work with other engineers, architects, surveyors, and general contractors. They help design and build homes, office buildings, bridges, automobiles, and airplanes; however, engineers are often specialized to help ensure that they have the required knowledge for their projects. Because of this, structural engineers play a unique role in designing and building, and their job differs from that of an architect.
Background
Structural engineering is a branch of civil engineering. Civil engineering deals with the built environment, or anything that people build or use as structures. Civil engineering is the oldest engineering discipline, as it encompasses any building that humans have done to create structures of their own. Although modern civil engineers use detailed mathematics and science, humans have been using their understanding of the world and its forces to build structures for countless years. Civil engineering has numerous disciplines. Transportation engineering is a branch of civil engineering that is responsible for designing safe and effective transportation systems. Water system engineering is a branch that deals with developing water systems that bring clean water to residents and dispose of wastewater. Material engineering focuses on developing the best possible materials to create the built environment. For example, material engineers could help develop the best possible concrete mixture for a particular structure. Earthquake engineering focuses on developing buildings and structures that stand up best to seismic activity. Structural engineering deals with creating structures that will stand up to outside forces and remain safe. The different branches of civil engineering overlap, and engineers from different disciplines work together to create a built environment that is safe and effective for humans.
Overview
Structural engineering is concerned with many of the same aspects as civil engineering but focuses mainly on creating structures that will withstand outside forces and function properly and safely. Structural engineering is a field that relies on the knowledge of many other fields. Civil engineering, in general, relies heavily on physics. Engineers must understand the laws of physics to be able to design structures that will remain safe and useful over time. They also have to use other types of mathematics, such as geometry, when designing structures. Structural engineers have to complete many equations while creating designs to ensure that structures will stay in place. Structural engineers also have to memorize and understand local and national building codes, which the engineers have to incorporate into their designs. Structural engineers should also have good communication skills. These engineers have to work with large teams and must fully understand what a client expects and wants from a building. Having good communication skills helps structural engineers meet expectations and complete the best possible products.
A structural engineer who is working on a project is just one member of a larger team. Modern building projects often include multiple structural engineers along with architects and general contractors. Structural engineers have different roles to play in the development, planning, and building of a structure. Often, structural engineers have specific titles reflecting the role they play. For example, a structural engineer of record oversees and manages the design of a structure to ensure that it will meet the requirements for the load-carrying structural system. This means that the engineer makes sure that the structure’s overall design will be strong enough to withstand forces such as the structure’s own weight, the weight of occupants or materials inside the structure, and forces from weather or seismic activity. Structural engineers have to determine the types of forces that are most likely to affect a building and make decisions about its design to help it remain as strong as possible in the conditions it will most likely face. For example, those designing bridges in California must take into account the strong seismic activity that bridges in that area could face. Structural engineers in New York may be able to focus less on seismic activity but must consider how the freezing and thawing of ice and water will affect bridges in that area.
Although structural engineers and architects both help plan structures, they have different jobs. The architect is often the main designer of a structure. He or she is concerned with the many elements of the structure such as ensuring that it is aesthetically pleasing and easy to use. The structural engineer does not think about the final appearance of the building as much as the way it will react to outside forces and continued use. Both the architect and the structural engineer want to create a well-liked, useful, safe structure, but the structural engineer has a narrower focus on the bones of the structure.
On larger construction projects, the structural engineer of record is the head structural engineer on the design team. This engineer may oversee a team of other structural engineers. A large project may have numerous structural engineers who develop plans, each one focusing on a specific part of the design. Each engineer will complete the calculations required to determine the best possible design for the various elements of the structure. The structural engineer of record reviews these designs and ensures that all the various elements work together to create a cohesive, sound structure.
The engineers working with the structural engineer of record are often called specialty structural engineers and each may work with a team to design specific elements of a structure such as the windows, columns, or roof. Specialty structural engineers might also collaborate with the construction teams that are working on the project. Specialty structural engineers have specific training in certain areas or specialties regarding a structure or its parts. This specialization helps these engineers create safer, well-designed structures. The specialty engineers often have to communicate with the structural engineers of record to ensure that all the pieces are working together and the overall design of the structure is sound. In the end, the structural engineer of record generally has the final say about a structure’s design.
Structural engineers help plan all the different elements of structures. They are involved from the beginning of a project and help decide the type of construction that will take place. Structural engineers must fully understand the building code for a specific area and the International Building Code (IBC) to ensure that the structure meets all legal requirements and is structurally sound. When choosing the type of construction, the engineer will have to decide the size, scale, and design of a building. He or she will also have to either help choose a location for a building or create plans that work with a predetermined location. Structural engineers also help design specific elements of structures. For example, a structural engineer working on a building will decide where the columns, which hold up the building, should be placed and how large they should be. The engineer would also help decide the location of the walls. The forces on a building have to be distributed in a specific way to ensure that the building remains strong. A structural engineer also helps determine the distance between the floor and ceiling, the location of windows and doors, the framing for stairs and elevators, and other elements.
Structural engineers play an important role in the design and construction of a building but also work on renovating and repairing buildings. They may help design building renovations, such as constructing additional floors on an office building. Structural engineers also play an important role when a structure or building is damaged by a fire, flood, earthquake, or corrosion. They may inspect the structure and determine whether it is sound and safe. If the structure is unsafe, a structural engineer may suggest demolishing it or developing a plan to repair it.
