Introduction to Structural Engineering
Structural engineering is both exciting and challenging as it involves a thorough understanding of physics, mathematics, and materials science. As a structural engineer, you must use complex mathematical equations and sophisticated software programs to design and evaluate structures. In addition to technical expertise, practical communication skills are also essential since you will collaborate with various professionals such as architects, contractors, and other project stakeholders on projects.
Now, you might still be studying engineering, a new structural engineer graduate,, or maybe in other related professions such as an architect, professional engineer or project manager. Some of this blog post might be obvious, and maybe some of it might not be what you expected. Let’s also try and dispel the publically accepted opinion that architects should get all the credit for structures too 🙂
Structural Engineering Fundamentals
To excel as a structural engineer, it is essential to have a solid understanding of various topics such as structural Analysis, mechanics of materials, earthquake engineering, and structural dynamics of water systems. Additionally, it is essential to be knowledgeable about common structural materials like steel, timber, and concrete and understand their behavior and properties under different environmental conditions and loads.
Critical Concepts of Structural Engineering
There are key structural design concepts that you need to understand before you move to the more advanced stuff deeply. Trust me, if you don’t learn these, you WILL struggle later on – I did for quite a few years early on in my career as I got high grades at university but lacked a mentor early on in my career, so I had to do a lot of self-study. In my experience, the following concepts are crucial to understanding in detail:
Stress & Strain and how these different materials react (yes, that’s that good old stress-strain curve you saw a thousand times at university).
Drawing accurate free-body diagrams
Load paths: The load path refers to the way a load takes through a structure. Understanding load paths is critical for designing safe and efficient systems.
Deflection and deformation
How this all ties together to determine the following:
Beam bending
Column loading
Frame action
NOTE:
If you want to learn about structural elements and design, then make sure to learn from my mistakes; check out my other blog posts for more in-depth info on structural elements:
Stress & Strain: the most fundamental of concepts you can ever escape from 🙂
Stress and Strain are essential for people who want to be structural engineers. Focus is like a push on something, measured by how much force per area. Strain is when the material changes shape because of the pressure.
Some materials are more accessible to break than others. Structural engineers use this information when using building materials for things like buildings and bridges. They ensure the structure can handle all the force it will experience while building materials are being used. They also pick out materials that can take lots of stress and Strain.
Drawing accurate free-body diagrams
As a marine structural engineer, I think it is essential for engineers to know how to draw free-body diagrams. These diagrams show us which forces are acting on a structure and what the inside of that structure looks like. By removing these diagrams, we can see if our system will be strong enough to withstand all forces. In addition, free body diagrams help us predict how a system will behave under different conditions and where it might need extra support.
I have used free-body diagrams to design various structures. No matter how complex they are,, they can ALWAYS be simplified down to a free body chart that is a statically determinate structure. As engineers, we will always simplify something if we can. Without the ability to draw accurate free-body diagrams, designing safe and reliable structures for the marine environment would be challenging.
Free body diagrams are essential for structural engineers. They help us understand the forces that act on building a structure, design the system to not break under those forces, and predict how the system will work if something changes. Therefore, all engineers should learn how to make free-body diagrams accurately.
Being able to quickly identify the correct load path of a structure into its foundations
Structural engineers must be good at figuring out how forces move through a structure. It is like playing Jenga, but you don’t take pieces away. This helps us make sure the system is safe and stable. It is like solving a puzzle, but if we get it wrong, it can be more severe than losing a puzzle piece.
To determine how the load is moved through a structure, for example, we have to think about different things, like how much load there is and what parts new structures are used. So it’s like being a detective, but instead of solving crimes, we’re trying to decipher how forces move around.
A structural engineer’s job needs to know how to figure out the load paths. It is like having an extraordinary power that helps us make sure the buildings we design are safe and secure. So let’s use our brains and get started! We don’t need any Jenga pieces or detective hats.
Deformation & Deflection: You have to bend it to take any load!
Hey engineer friend! Let’s talk about deformation and deflection. They are essential for engineers to know. Deformation is when a material changes shape because of force, like bending a spoon. Deflection is how much a structure moves when it has pressure on it.
Structural engineers need to know how to figure out deformation and deflection. Deformation and deflection can affect how safe a building or bridge is. To design a structure, engineers do calculations and use computers to check if it will be strong enough. They look at things like the material used, where the weight is placed, and what type of support it has to ensure it won’t break down.
It is essential to ensure bridges and other structures can handle the weight of people and cars. As structural engineers, it is our job to design safe things. We must not make mistakes when we do the calculations, or else bad things could happen. That’s why deformation and deflection are not something civil engineers get to joke about.
That’s great, Adam, but how does it all go together?
As a structural engineer, it is essential to know critical structural engineering concepts. These concepts help you design structures and look at simple structures like beams, frames, and columns. I will explain these concepts and how they are used to design structures.
Equilibrium is an essential idea in structural engineering. This means that all the forces on a structure must be balanced. Engineers use this to determine which forces are acting on a system and ensure they are even. This is especially important for beams and columns because it could break or fall down if the point isn’t balanced.
Structural engineers in construction must understand stress and Strain. Stress is the force inside a material, and Strain is what happens when stress is added. By understanding stress and Strain, engineers can predict how materials will act with different weights on them. They use this to make sure that beams do not break by making sure the materials don’t go over their limits.
Deformation and deflection are important for engineers. Deformation is when a structure changes shape or size because of something on it. Deflection is when the structure moves away from its original place because of the same thing. Engineers need to know how much deformation and deflection will happen to make sure the structure is strong enough to hold what it needs to have. This is especially true for frames, where they must be solid.
Structural engineers need to understand load paths. Load paths are how the weight from a building passes through it to get to the ground. Engineers use load paths to make sure facilities are strong enough and safe for people. This is especially important when making columns, which need special attention to hold up all the weight on them.
Structural engineering is essential for making and studying structures like beams, frames, and columns. Equilibrium, stress and Strain, deformation and deflection, and load paths are all fundamental ideas civil engineers have to consider when designing these structures. If engineers understand these concepts well, the designs will be safe and robust enough for their purpose.
That’s great – now, how the heck do I learn this?
I am a structural engineer. To learn how to do this job, find someone who knows how and ask them many questions. When I started, I wasn’t lucky to have a mentor who answered my questions and taught me what to do. I had to do a lot of self-study, so it is not impossible to do it this way, but if you combine self-study with a mentor, your progress will be exponential. Even if the questions seem easy, don’t be scared to ask them. Everyone had to start somewhere!
If you want to learn the structural engineering basics as a beginner, you may consider enrolling in an online course. There are various options available that can teach you the structural engineering basics from your home. However, it is essential to conduct thorough research and select a trustworthy course that covers the topics of your interest. Most importantly, it, allows you to get a firm grasp of the fundamentals before they move onto more advanced subjects like virtual work, moment redistribution,, or indeterminate structures.
A course can give you knowledge, but it is not the same as real-world experience. So find someone to teach you, a mentor. Ask them lots of questions. Maybe one day you can be a mentor for someone else! If you have more questions, I am here to help.
