HandyBeam vs Structural Dynamics Visualizer

Whether you are a student looking for a convenient app that helps you solve statics problems pertaining to beams, or an engineer/architect who wants to make structural checks on-the-go: HandyBeam provides an intuitive, easy-to-use tool that allows you to do just that! INTERACTIVE DEFLECTION, SHEAR, AND MOMENT DIAGRAMS - Get instant feedback as you add and drag the different nodes along the beam with intuitive touch gestures. INSPECT CRITICAL VALUES RESPONSIVELY - Toggle the "max values" labels to monitor the maxima as you change your beam configuration. - You can even place an "inspection tool" at a fixed location and monitor the change in value in that location. TOOLS AVAILABLE - A wide range of load and support tools are available in the app, including: • Pinned support • Fixed support • Linear spring • Rotational spring • Plastic hinge • Point load • Concentrated moment • Distributed load • Inspection/station tool

Structural Dynamics Visualizer is an interactive educational tool for exploring the behavior of vibrating structural systems. Visualize free vibration, forced vibration, mode shapes, sinusoidal ground motion, and earthquake response using animated structural models and synchronized response plots. Explore single-degree-of-freedom and multi-degree-of-freedom systems, including carts, shear frames, cantilevers, and vertical spring-mass systems. Adjust model parameters such as mass, stiffness, damping, initial displacement, initial velocity, forcing amplitude, forcing period, and number of degrees of freedom, and immediately see how those changes affect structural response. Features include: • Free-vibration response and damping behavior • Forced vibration and resonance visualization • SDOF and MDOF structural models • Mode shapes and modal response • Shear-frame and cantilever systems • Sinusoidal base excitation • Earthquake response using recorded ground motion • Interactive parameter controls • Animated structural deformation • Response histories and natural-period visualization Structural Dynamics is designed as a teaching and learning aid for students studying structural engineering, earthquake engineering, vibrations, engineering mechanics, and related subjects.
