Frame Analyzer — Ebora Online Tutorial Services

🏗️ Frame Analyzer

Build a 2D plane frame, apply loads, and solve it by the Direct Stiffness Method — reactions, joint displacements, member end forces, and per-member axial (N), shear (V), and moment (M) diagrams. Tap Analyze Frame, then download a full PDF report for your submission.

UDL-y / UDL-grav / Axial: uniform along [a, b]. w₂ unused.
TUDL-y / TUDL-grav: linearly varies from w at a to w₂ at b (set one to 0 for triangular).
Point-y: point load ⊥ to member at a. Point-x: axial point load at a. Moment: concentrated couple at a (CCW positive). For these three, w is the magnitude; b and w₂ are unused.
