Girders TRIZ Cases
- Unitary Steel Joist Fire Resistance and Cost
Composite steel and wood materials resolve the trade-off between high installation costs and poor fire resistance in residential construction.
- Triangular Prism Core Beam with Triaxial Fabric Cover
A lightweight beam structure uses a triangular prism core wrapped in triaxial fabric cover to enhance structural rigidity.
- Escalator Truss Joint Assembly Oil Leakage Prevention
Bent barrier plates overlap to cover gaps between truss bottom plates, forming a mechanical seal for lubricating oil.
- Open Lattice Composite Truss via Maypole Braiding
Maypole braiding large prepreg yarns produces open lattice trusses that eliminate bolted joint stress concentrations while achieving significant weight savings.
- Universal Structural Member Anti-Rotation Design
A universal structural member uses an L-shaped configuration to prevent rotation on horizontal bars.
- Self-Confining Ceramic Articles with Fabric Mesh Reinforcement
Continuous fabric mesh reinforcement confines ceramic matrix articles, preventing catastrophic collapse from steel corrosion.
- Bi-Metallic Connector for Mass Timber Shear Walls
A bi-metallic connector transitions from high to low stiffness under seismic loads, enabling mass timber shear wall panels to dissipate energy through plastic deformation.
- Reusable Concrete Support Beam for Adaptable Building Frames
A reusable concrete support beam with detachable steel connections enables adaptable building frame designs.
- Hybrid Composite Bridge Girder Weight Reduction
A hybrid composite girder with a modified V-shaped cross section reduces structural weight using fiber-reinforced polymer materials.
- Glass Beam Connection via Welded Reinforcement and Adhesive Bonding
Welded reinforcement sections join glass beam elements through adhesive bonding, maintaining transparency while preventing stress concentration from drilling.
