Hollow PC Composite Column for SRC Structures and SRC Construction Method Using the Same

Hollow PC Composite Column for SRC Structures with Enhanced Sectional Performance via Steel Shapes and Hollow Sections

This technology is a hollow PC composite column that integrates structural steel and reinforced concrete. It consists of multiple vertically arranged steel shapes connected by tie plates, tie reinforcement wrapping around the steel shapes, and a precast concrete casing that forms a hollow section inside the steel shapes.

Conventional SRC columns often involve complex on-site construction processes, making it difficult to simultaneously improve sectional performance and simplify installation.

By utilizing precast components and incorporating a hollow section to maximize sectional performance, this technology simplifies on-site work while enhancing the structural efficiency of SRC buildings.

Key Features:

• Multiple steel shapes arranged vertically and spaced apart within the column cross-section
• Tie plates installed to connect the multiple steel shapes at their midsections
• Tie reinforcement wrapping around the exterior of the steel shapes to provide lateral confinement
• Precast concrete casing that covers the pre-assembled steel shapes, tie plates, and reinforcement to form an integrated hollow section
