Background technique

The trusses connected by resistance spot welding with steel bars as the upper chord, lower chord and web are called steel trusses. The combined load-bearing slab that the steel truss and the bottom slab are connected as a whole by resistance spot welding is called the steel truss floor slab. Reinforced truss floor deck has the characteristics of high cost performance, short construction period, convenient transportation and installation, reasonable force distribution, high construction quality, and good crack resistance. It is a commonly used building material in the current construction industry.
