Key Features:

​

Member Bending Moment: Calculates internal bending moments in each structural member. Useful for evaluating flexural performance under applied loads.

​

Member Shear Force: Determines shear force distribution along members. Helps in checking shear capacity and designing shear reinforcement.

​

Member Normal Force: Computes axial (normal) forces in structural elements. Essential for tension/compression checks and stability analysis.

​

Nodal Reactions (Fx, Fy, My): Evaluates support reactions in horizontal, vertical directions, and moment. Ensures equilibrium and correct support behavior.

​

Nodal Displacement and Rotations: Calculates translations and rotational displacements at nodes. Helps in assessing deformation and serviceability criteria.

​

First and Second Order Analysis: All results can be obtained using both linear (1st order) and geometrically nonlinear (2nd order) analysis. Captures both basic and advanced structural behaviors.

​

Critical Buckling Eigenvalue: Determines the load factor at which buckling is expected to occur. Crucial for stability and safety checks.

 

Critical Buckling Eigenmode: Provides the buckling mode shape associated with critical eigenvalue. Useful for visualizing potential failure patterns.

 

Frequency Eigenvalue: Calculates natural frequencies of the structure. Supports dynamic analysis and helps avoid resonance.

 

Frequency Eigenmode: Determines corresponding mode shapes for each natural frequency. Aids in understanding dynamic behavior of structures.

 

Node Sensitivity: Analyzes the sensitivity of response at each node with respect to design changes. Useful in optimization and design refinement.

​

Axial Stiffness Sensitivity: Evaluates how changes in axial stiffness affect overall response. Assists in stiffness tuning and material efficiency.

 

Bending Sensitivity: Assesses sensitivity of structure to variations in bending stiffness. Helps in improving structural resilience and performance.
