HiTAB Girder Overview

Overview

Introduction

  • Steel composite long-span bridge that has applied the steel box structure to the positive bending moment section and the truss structure to the negative bending moment section.
  • Improved structure, constructability, and economy through the combination of two verified structure systems.
  • Enhanced stability against wind and an advanced aesthetic value by applying the truss structure at the mid support.
