Using Virtual Joist Girders in RISAFloor

Modern building design is increasingly defined by hybrid systems. Engineers are combining multiple building materials within a single structure to meet demands for efficiency, constructability, and performance. This approach allows each material to be used where it performs best, but it also introduces a level of complexity. Coordinating different material behaviors within one structural system and load path is no longer a niche challenge. It is becoming standard practice. What is Multi-Material Structural Design Multi-material structural design is the practice of using different building materials in one coordinated structural system so that load paths, stiffness, and movement are all working together. In real projects, this shows up as: Mass timber framing on top of a concrete podium Steel transfer beams carrying concrete slabs above Masonry cores tied into wood gravity framing These systems are now common in commercial and residential projects, especially as teams look for more sustainable and efficient buildings. Why Multi-Material Design Matters Using multiple materials allows engineers to fine-tune structural systems and capitalize on the best attributes of each material. Multi-material structural systems help you: Provide stiffness where you need it, such as at a concrete core Allow for long spans and complex geometries by utilizing steel…
