What Is Prestressed Steel Structure

Prestressed steel structure (prestressed steel structure) means that the steel structure or components are pre-stressed by a specific method before the load is applied to the structure. The sign of the stress is opposite to the sign of the stress caused by the load; when the load is applied, to ensure Safe and normal use of the structure. The structure or component first offsets the initial stress, and the role of prestress should also be considered, and then the steel structure that works according to the general stress condition is called prestressed steel structure.
