| 中文摘要: |
| 采用不同原材料调整混凝土强度、表观密度及体积稳定性，配制普通自密实混凝土（PT）、添加膨胀剂自密实混凝土(EPT)、自密实轻集料混凝土(LC)、添加膨胀剂自密实轻集料混凝土(ELC)。通过试验研究和采用ANSYS有限元分析，建立方形钢管混凝土轴心荷载模型，研究薄壁方形钢管自密实混凝土与钢管复合叠加应力应变规律。 |
| 英文摘要: |
| By using different raw materials concrete strength, apparent density and volume shrinkage are adjusted to configure ordinary self-compacting concrete (PT), added expansive agent self-compacting concrete (EPT), self-compacting lightweight aggregate concrete (LC) and added expansive agent self-compacting 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 . |
