| 摘 要： | 在实腹式钢骨混凝土异形柱和桁架式钢骨混凝土异形柱的基础上,提出了一种新型的异形柱——蜂窝状钢骨混凝土异形柱.利用ANSYS软件,分析了钢骨腹板开洞率、配钢率、加载角、偏心距等因素对该新型异形柱力学性能的影响.分析结果表明:钢骨含钢量越大,加载角越大及偏心距越小,柱子的承载力也越大,而钢骨腹板开洞率对柱子的承载力影响是有限的.本文的研究成果,为该新型钢骨异形柱在工程中的应用提供了理论依据.

| Abstract: | Based on the full web SRC special-shaped columns and the truss type SRC special-shaped columns,honeycomb SRC special-shaped column is conducted.The software ANSYS is used for the analysis of the influential factors such as the web hole ratio,the steel ratio,the loading angle,the eccentricity to the mechanical properties of the new type column.The results indicate that increases in steel ratio and the loading angle and decreases in eccentricity are advantageous to the ultimate load-bearing capacity of the me... |
