Fap-3V4

FAP-3 V4 by Kozo System (構造システム) is a professional structural analysis application for three-dimensional framed structures. It helps engineers model buildings and other space-frame systems, define loads and combinations, and run reliable analyses to assess stiffness, stability, and overall structural behavior. The software offers an intuitive modeling environment, efficient solvers for common analysis tasks, and clear visualizations of deformations, member forces, and reactions. It supports streamlined reporting and interoperates with other Kozo System tools to improve workflow continuity from analysis through design documentation.

Key capabilities:

• 3D frame modeling for beams, columns, braces, rigid links, supports, and springs
• Flexible load definition, combinations, and basic staging workflows
• Analysis options for linear static problems and modal evaluation of dynamic characteristics
• Result visualization with diagrams, contour views, envelopes, and tabular summaries
• Quality checks and model diagnostics to help detect input issues
• Reporting and data export to support technical submittals and collaboration

Typical uses include building frames, industrial structures, towers, and other space-frame applications where dependable analysis and clear deliverables are essential.
