• Civil / Structural Engineer Freelancer · Freelance Jan 2026 – Feb 2026 1 mos United States This project involved the comprehensive 3D structural analysis, design, and optimization of a G+6 Story Residential RCC Frame Structure. The primary objective was to translate complex architectural blueprints into a structurally sound, code-compliant, and cost-effective reality. By employing advanced Finite Element Analysis (FEA), the design was fully optimized to withstand gravitational, wind, and seismic forces while avoiding expensive over-engineering.
  
  Scope of Work & Engineering Workflows
  Geometric Modeling:
  Established highly precise grid systems, story heights, and material properties.
  Load Calculations & Combinations: Calculated and assigned Dead Loads (DL), Live Loads (LL), and Superimposed Dead Loads (SDL). Applied dynamic lateral forces—including Wind Load (WL) and Seismic Load (EQ)—using response spectrum analysis tailored to regional seismic zones and wind speed parameters.
  Code-Compliant Analysis: Executed full Finite Element Analysis (FEA) conforming to BNBC (Bangladesh National Building Code), ACI 318 (for concrete design), and ASCE 7 (for load combinations).
  Stability & Safety Verifications:
  Performed and passed critical design checks, including: Story Drift & Displacement limits to control lateral sway.P-Delta effect checks to account for secondary displacements.Base Shear and Overturning Moment ratios to ensure overall structural equilibrium.
  Project Outcomes & Deliverables Material-Optimized Design:
  Refined structural member sizes (beams, columns, and slabs) to maintain code compliance while saving approximately 10% to 15% in concrete and rebar volumes compared to baseline layouts.Seismic/Ductile Detailing: Drafted precise detailing for beam-column joints and critical confinement zones, ensuring high energy dissipation capacity during potential seismic events.Permit-Ready Structural Drawing Package: Generated a comprehensive, layered AutoCAD drawing set containing column layouts, foundation layouts, beam-column reinforcement schedules, and slab reinforcement details.Project Status: Successfully Completed & Approved. The final structural analysis report and design drawings successfully passed local municipal permit reviews, and the project is fully cleared for on-site execution.
