High-Rise Steel Structure
High-rise steel structure generally refers to a structural system with six or more layers (or more than 30m), which is mainly connected or welded by section steel and steel plate, and then connected and welded. Steel frame structure and steel frame-concrete core tube structure are commonly used in high-rise steel structure. The latter is widely used in modern high-rise and super high-rise steel structures. In fact, it is a steel-concrete hybrid structure.
As an important load-bearing structural system, steel frame structure is widely used in public buildings such as residences, offices, and entertainment.
