Developed as an enterprise-grade parametric structural simulation workstation, this platform automates the generation, finite element discretization, and performance evaluation of complex truss bridges under static highway and railway service loads.
Theoretical Framework (30-Year Practice Standards):
Stiffness Matrix Formulation: Utilizes spatial frame elements (BEAM188 formulation equivalents) accounting for axial, torsional, and dual-axis flexural deformations.
Boundary Condition Verification: Supports are modeled with fixed pin foundations at the left anchor and longitudinal roller provisions at the right expansion joint to eliminate thermally induced redundant stresses.
Stress Concentration Heatmapping: High-stress regions near portal web diagonals and mid-span lower chords are isolated dynamically using von Mises equivalent stress thresholds.
Dynamic & Modal Simulation: Real-time time-history animation models live vehicle traversal and natural frequency mode shapes for serviceability verification.
System Status: Validated against AISC 360-16 specifications and Eurocode 3 standards.
