Customers who are familiar with the reinforcement technology of the planting bar adhesive reinforcement must know that the reinforcement force needs to be calculated when the building is strengthened. However, many people do not know how to calculate the stress of the planting bar. It is recommended that you consult the professional organization. Here we first give you an introduction.

How to calculate the pull-out force of building reinforcement?
The calculation process of the pull-out force of epoxy resin is very simple. One formula plus two tables can be used to query the data of the descendants. For details, please refer to the specification and the test value of the load-carrying capacity. Next, we take a look at the specific calculation process:
The specimen drawing capacity test value table helps you quickly solve the problem of the pullout force of the planting bar.
The formula for calculating the planting bar in the Code for Concrete Structure Reinforcement Design GB50367-2013 is:
N=As×fy;
As: The area of the steel bar is obtained; fy: The design value of the tensile strength of the steel bar is obtained.
For example, if the pull force of the HRB335 steel bar of 14mm is calculated, the As is 153.9mm2 and the fy is 300N/mm2. Then N=As×fy=153.9×300=46170N=46.2kN
In particular, if you are going to perform non-destructive pull-out detection, you need to multiply by a factor of 0.9, ie: N'=46170*0.9=41553N=41.6KN
