Hotel Building Renovation and Structural Reinforcement Case
--Project
This project involves the overall renovation and reinforcement of a hotel. Due to functional adjustments, increased loads, and structural aging, safety hazards exist, including insufficient load-bearing capacity of floor slabs and multiple cracks in beams, slabs, and columns. Systematic structural reinforcement is required to ensure building safety and normal operation.
--Main Defects
• Floor Slabs: Load-bearing capacity does not meet post-renovation requirements; stress cracks appear on the bottom and surface of the slabs.
• Beams: Insufficient bending and shear bearing capacity; cracks appear on the sides and bottom of beams.
• Columns: High axial compression ratio; localized concrete damage and cracking; insufficient vertical load-bearing capacity.
--Reinforcement Plan
• Floor Slab Reinforcement:
Double-sided bonding of 230g carbon fiber cloth (full application to the tension zone of the bottom slab, strip application to the support zone of the top slab) to improve load-bearing capacity and seal cracks;
• Beam Reinforcement
Steel plate bonding reinforcement, with steel plates bonded to the bottom of the beam to enhance bending resistance and steel hoops bonded to the sides of the beam to enhance shear resistance;
• Column Reinforcement
External steel jacketing reinforcement to comprehensively improve the vertical load-bearing capacity and overall integrity of the columns.
