Large-Span Ceiling Bracing System Using In-Plane Stiffness Reinforcements

Seismic Ceiling Bracing System for Large-Span Spaces Using In-Plane Stiffness Reinforcements and Braces

This technology consists of a T-bar assembly arranged in a grid pattern beneath the building slab, T-bar brackets positioned at the intersections, in-plane stiffness reinforcements coupled between the brackets, and braces connected to the upper surface of the reinforcements via connection brackets and anchored to the slab in multiple directions.

Conventional large-span ceilings have struggled to maintain sufficient in-plane stiffness, making them vulnerable to lateral forces such as earthquakes.

By enhancing ceiling stiffness and energy dissipation through in-plane stiffness reinforcements and multi-directional bracing, this technology improves the seismic performance of ceilings in large-span structures.

Key Features:

• T-bar assembly arranged in a grid pattern beneath the building slab, with T-bar brackets positioned at regular intervals at the intersections.
• In-plane stiffness reinforcements coupled between T-bar brackets to form a continuous row.
• Connection brackets coupled to the upper surface of at least one in-plane stiffness reinforcement to connect the braces.
• Braces connected to the connection brackets in different directions and anchored to the slab to resist lateral forces.
