PROJECT: STRUCTURAL REINFORCEMENT WITH EXTERNAL PRESTRESSED CABLES AND CFRP.
INVESTOR: PHU TAI JOINT STOCK COMPANY
EXECUTING UNIT: BKG JOINT STOCK COMPANY
Structural reinforcement by external prestressed cables technology combined with CFRP composite material is effective in lifting the floor load from 250 Kg/m2 up to 600 Kg/m2. During the tensioning process, the structural monitoring system is used to monitor the construction process to achieve the highest safety and efficiency.
