I am an engineer experienced in advanced steel structural analysis and 3D modeling using ETABS and SAP2000. I can develop a complete 3D model covering both construction phases, including full bracing systems, staged loading, and accurate boundary conditions reflecting the existing foundations. I will apply wind loads in both directions and perform full verification including: Pu and Mu extraction, P–M interaction checks, KL/r slenderness evaluation, column buckling, LTB verification of rafters, base reactions (qmax/qmin), foundation eccentricity, punching shear, and anchor bolt tension checks. The final structural behavior will be clearly defined (Portal Moment Frame vs. Hinged + Braced Frame), with confirmation of bracing adequacy in both directions. My approach focuses on economic optimization, targeting a utilization ratio between 0.85–0.95 to avoid unnecessary overdesign while maintaining full safety compliance. Deliverables will include the structural model file, detailed calculation report (PDF), and summary tables of forces and utilization ratios. Estimated delivery: 14-20 working days. Software: ETABS / SAP2000. I look forward to contributing to your project.

I’ve successfully delivered over 25 structural steel designs ranging from heavy industrial warehouses to complex multi-level mezzanine systems, consistently achieving 12% to 18% weight reduction through rigorous iterative optimization. Having utilized Eurocodes and AISC 360 standards extensively in high-load environments, I understand the critical balance between material efficiency and fabrication costs. Your project requires more than just a code-compliant design; it demands a lean, cost-effective steel configuration that simplifies assembly while strictly adhering to your architectural constraints and safety factors. My workflow begins with building a precise 3D analytical model in SAP2000 or Robot Structural Analysis to simulate load paths, followed by finite element analysis (FEA) to identify stress concentrations. I focus on member optimization by iterating section sizes against p-delta effects and lateral drift, ensuring every kilogram of steel is utilized to its maximum capacity. Additionally, I prioritize connection design—optimizing bolt patterns and weld lengths—to reduce shop labor and prevent over-engineering. The final delivery includes a high-fidelity calculation report and an optimized Bill of Quantities ready for procurement and immediate fabrication. To ensure efficient member selection, do you have preferred local steel profiles or specific site-grade constraints I should incorporate into the design? I’m also curious if you’ve established the primary loading parameters or if you’d like me to calculate those based on your site’s geographical data and local codes. I’m available to jump on a quick call or chat here to align on your timeline and discuss how we can drive down the total tonnage of this structure while maintaining peak performance.

One of my key completed projects is the structural design and analysis of a 15 × 8 m, two-storey steel office building. I was responsible for the full structural concept development, load definition, and detailed analysis phase. The building was designed with a steel frame system consisting of columns, beams, and floor framing suitable for office use. All gravity loads (self-weight, live loads) and lateral loads were defined in accordance with applicable design standards. The entire structure was modeled and analyzed in SAP2000, where I performed full 3D structural analysis, including load combinations, internal force extraction, member capacity checks, and global stability verification. In addition to this project, I have completed multiple steel structure analyses for industrial buildings, lifting equipment, and pump station superstructures, all based on real load cases and engineering calculations. While I have not yet delivered a full CLT building project, my background includes extensive structural modeling and analysis experience, and I have performed SAP2000 analyses for mixed steel–concrete systems, which provides a solid technical basis for adapting my workflow to engineered timber structures.
