Gaoyou hospital retrofitting, steel rebar planting
The qualification standard for pullout test is: when pull-out test results conform to the following conditions, it is qualified; the drawing force has reached the design requirement (or has reached the yield value of steel bars), and the reinforcement has not been pulled out. The reinforcement is pulled out, but the form of the damage is that the concrete is destroyed and not the structural adhesive is destroyed.

What is the principle of CFRP composite strengthening?
the use of the carbon fiber adhesive, can work well, greatly improving the tensile strength of carbon fiber, the carbon fiber reinforcement must first make carbon fiber work together, so the adhesive on CFRP plays a key role, it is necessary to ensure the carbon filaments work together and work together to ensure that the carbon fiber cloth and structure, so as to achieve the objective of strengthening.

Which buildings need seismic strengthening?
In order to protect the life and property, the building have to do seismic strengthening. However, some buildings have not been aseismatic in the design and construction, which requires the seismic identification and reinforcemen . In particular, the old buildings, such as the general hotel, need to be identified as a whole in the new era and to be reinforced in accordance with the design.
