2D Frame Analysis Dynamic Edition is a specialized finite element method (FEM) software developed by Engissol Ltd. for civil and structural engineers. It focuses on the linear/non-linear static and dynamic engineering analysis of multi-span beams, trusses, and portal frames.
When combined with Real-Time Stress Testing, the platform processes time-dependent load data—such as seismic waves or blast forces—and immediately updates internal stresses, node deflections, and bending moments. Core Analytical Capabilities
Dynamic Time History: Computes the exact structural response step-by-step against time-varying loads.
Response Spectrum: Evaluates earthquake loading scenarios using standard design spectrum profiles.
Modal Analysis: Estimates natural frequencies, eigenvalues, and specific mode shapes for structures.
Non-Linear P-Delta: Account for secondary structural stresses caused by major displacements under heavy axial loads. Pre-Processing Features
Material Libraries: Built-in properties for concrete, timber, aluminum, and hot/cold-rolled steel.
Section Profiles: Global databases including AISC, European, British, Chinese, and Australian shapes.
Flexible Modeling: Custom cross-sections, spring supports, and end-length offset variables.
Interactive GUI: Modifies units on-the-fly and generates parametric structural templates. Core Output Metrics
The application handles the real-time solving of engineering problems using an optimized beam element core:
