By using different raw materials concrete strength ,apparent density and volume shrinkage are ad‐justed to configure ordinary self -compacting concrete (PT ) ,added expansive agent self -compacting con‐crete (EPT) ,self-compacting lightweight aggregate concrete (LC) and added expansive agent self -compac‐ting lightweight concrete (ELC) .Through experimental research and ANSYS finite element analysis ,the square steel concrete columns axial load model was built ,and the thin -walled square steel tube inner self compaction concrete with steel composite superimposed stress strain were also studied .
