Structural Design detailing of a building with raft foundation by me. The draughting is actually awesome or what do you think about my draughting? #draughtman #civilengr #AutoCAD #StaadPRO #structuralengineer #Engineering

The Backbone of Modern Construction: Steel Detailing 🏗️ Did you know that accurate steel detailing is not just about drawings? It’s about ensuring safety, efficiency, and cost-effectiveness on every project. 📐 Why does steel detailing matter? Precision: A single error in detailing can lead to delays or cost overruns. Collaboration: Detailers are the bridge between engineers, architects, and fabricators. Sustainability: Efficient designs minimize material waste, promoting eco-friendly construction. 🌟 Fun Fact: A steel structure weighing 500 tons can take over 10,000 hours of detailing work to ensure flawless assembly on-site! 💡 Question for you: How do you see technology like Tekla and AutoCAD shaping the future of construction detailing? Let’s discuss! Share your thoughts, experiences, or questions in the comments. Let’s learn from each other and grow together. #PEB #SteelDetailing #ConstructionInnovation #EngineeringExcellence #Tekla #AutoCAD #StructuralEngineering #nisd #asic #BuildingTheFuture #BIM #SteelConstruction #SustainableConstruction #ConstructionTech #DetailingExcellence #Collaboration #AEC

🎓 Semester 1 Highlights at TAFE Queensland – Road Design and Structural CAD Work 🎓 In my first semester at TAFE Queensland, I jumped into CAD design for civil and structural engineering, getting hands-on experience in road layout and structural detailing. Here’s a quick snapshot of what I worked on: ▪ ROAD SETOUT PLAN DRAWING What I tackled: -Divided the road layout based on the plan, drawing cross-section control lines and adding kerbs and channels. -Learned how to draw the longitudinal section control line to make sure everything aligned with precision. How I approached it: Used Brisbane Standard Drawings (BSD - 2001) as my guide, overlaying survey data with the .dwg file to see how the new design interacted with the existing site. ▪FOOTING AND COLUMN DRAWING What I tackled: -Created detailed drafts for footing layouts, footing pads, columns, roof plans, portal frames, wall frames, and I-beam connections. -Developed clear sectional views of columns, complete with dimensions, column types, and other key details. ▪How I approached it: -Selected the right I-beam types and sizes for each section, adding bolts and stiffener plates for structural accuracy. -Marked session points to label column and I-beam details according to industry standards, keeping everything organized and easy to follow. It’s been a great experience so far, building a strong foundation in CAD and civil design. Excited to keep learning! #civilEngineering #CAD #AutoCAD #TAFEQueensland #RoadDesign #StructuralDetailing #Engineering #Civildrafter #drafter

After many years as a structural engineer, I realized that fundamental knowledge is essential to simplify complex calculations based on logical foundations. One must make assumptions within permissible limits (something true engineers "feel" in the data to provide reasonable boundary conditions for the problem at hand) and perform calculations using simple formulas. Naturally, the output must be "felt" once again. A basic example is as follows: for a bending section with (1) an economical design, never use double reinforcement to resist compression, (2) only use single reinforcement for tension, (3) concrete should resist compression within allowable limits, and finally, (4) the bending section remains flat after deformation. With these four assumptions, arguing that the calculated reinforcement for bending (As) comes from the critical moment of the section (Mu) divided by the effective height after placing the reinforcement (d) will yield an equal tension/compression couple. To calculate the tension reinforcement, divide the tensile force couple (Ftu) by the design strength of the reinforcement (fyk/1.15-gamma_s), converting units to get the result in cm² for the reinforcement area. Voila, it's quite simple, isn't it? Similarly, for shear force, assuming the inclination angle of the compression strut is 45 degrees, i.e., the cotangent of the angle is 1.0, the calculation formula for vertical shear reinforcement (Asw) parallel to the bending section at the location of maximum shear force per unit step (s) is simply the value of the critical shear force (Vu) divided by the effective height after placing the reinforcement (d), further divided by the design strength of the shear reinforcement (fywd). Cheers, the result is quite simple. I would like to share this with young engineers who see calculations as too complex to be done by hand, so they gradually become familiar with this result to control the output of reinforced concrete design models or software.

The aim of the document below is to provide the anticipated outcomes after completing a residential structural design.  I started the document with a quick overview of the most important values to choose and decisions to make while we are still in the design phase. In addition, I briefly detailed the design steps in the introduction. The next section is about the shapes of rebar needed in each element and the quantity of each shape. Following that, I presented the final BOQ results, the shop drawings, and the structural checks.  Please feel free to inform me in the comments if I missed any of the expected results. #Engineering #StructuralDesign #StructuralEngineering #CivilEngineering #AutoCAD #SAFE #ETABS

Did you know...Tekla Structural Designer can also be used with concrete and timber structures? While the design and analysis software may be most well-known amongst the construction industry for its steel capabilities, it is just as valuable for concrete design: ✅ Foundation Design ✅ Staged Construction Analysis ✅ Software integration ✅ Multi-material #engineering #software #concrete #TeklaStructuralDesigner
