When the assembled steel structure building is subjected to lateral force, the lateral displacement of the steel frame supporting structure 1 and the lateral displacement of the steel bar truss floor supporting plate 2 are large. Because the steel frame supporting structure 1 is connected with the wall body, the steel bar truss floor supporting plate 2 is also connected with the wall body, and the rigidity of the ALC plate 3 in the wall body is high, the wall body and the steel frame supporting structure 1 and the wall body and the steel bar truss floor supporting plate 2 can be coordinated and deformed in order to prevent the wall body from being damaged when being subjected to lateral force, and the steel frame supporting structure 1 and the steel bar truss floor supporting plate 2 can not be extruded to damage the wall body in the lateral displacement process.
Further, in order to make the wall body and the steel frame support structure 1 and the wall body and the steel bar truss floor support plate 2 capable of being deformed in a coordinated manner, the connection mode between the rest part of the ALC plate 3 except the bottom part in the wall body and the steel frame support structure 1 can be flexible connection, and the connection mode between the ALC plate 3 in the wall body and the steel bar truss floor support plate 2 positioned on the steel frame support structure 1 can be flexible connection.
