Calculated load is different from standard load?

In the construction industry, how is calculated load different from standard load?

Answer you:

Calculated load is different from standard load in that: calculated load = standard load x overload coefficient n.

This overload coefficient is always greater than 1. Therefore, the calculated load is always greater than the standard load. Standard load values and overload coefficients can be referred to in TCXD 2737-1995 (Loads and impacts - Design standards)

The reason for this is because the standard load for each type of construction and each type of structural component is actually only taken from experimental methods (and then statistics) and from experience, so no one dares to guarantee that This value is exactly 100%.

And no one can guarantee that the actual load in future use will never exceed that number. Not to mention, there is also the reduction in load-bearing capacity of the structure during use (fire, corrosion...) or during construction (reduced/poor quality materials, improper construction techniques). , trim material...). Therefore, to ensure safety, the load included in the design must always have an accompanying overload coefficient.
