How to Select UHPC Strengthening Components for Old Building Renovation? Qinglong UHPC Strengthening Technical Guide

In the renovation of old buildings, the selection of UHPC strengthening components must be determined according to the structure type, degree of damage, and strengthening objectives. Commonly used strengthening components include: slab strengthening layers (30-50mm thick), beam strengthening jackets (40-60mm thick), and column strengthening jackets (50-80mm thick). Structural calculations are required when selecting components to ensure safety and reliability.

Regarding selection principles, consider: first, assess the condition of the original structure, including concrete strength, reinforcement configuration, and crack conditions; second, determine the strengthening objective, whether to increase load-bearing capacity, improve stiffness, or enhance durability; then choose the strengthening method, with slabs commonly strengthened using UHPC layers and beams and columns using UHPC jackets; finally, carry out detailing design, including connection construction and workmanship. This systematic selection ensures the strengthening effect.

Selection of Strengthening Component Types

Slabs are strengthened with UHPC layers, 30-50mm thick; beams are strengthened with UHPC jackets, 40-60mm thick; these choices are highly targeted.

Key Points of Structural Calculation

Verify the increase in load-bearing capacity; control the stiffness of the strengthened structure; these calculations ensure safety.

Detailing Design Priorities

Reliable connection construction; convenient workmanship; these designs guarantee effectiveness.

Construction Technique Requirements

Clean interface treatment; dense casting; sufficient curing; these requirements ensure quality.

Strengthening component selection requires professional assessment. Qinglong UHPC has extensive experience, with remarkable strengthening results.
