［摘要］為了研究鋼骨混凝土異形柱的受力性能和影響因素，在試驗研究的基礎(chǔ)上編制了非線性分析程序。對非線性分析得到的承載力與試驗進行比較可知，二者誤差較小。分析了加載角、偏心距、含鋼率、混凝土強度等級以及肢長厚比對構(gòu)件承載力的影響。結(jié)果表明：含鋼率的變化對構(gòu)件的極限承載力影響明顯，且極限承載力隨著截面含鋼率的增大而增大。最后對十字形實腹式鋼骨混凝土異形柱實用設(shè)計方法進行了探討。

Abstract:The procedure of nonlinear analysis has been compiled based on experiment for studying the force performance and effect factors of steel reinforced concrete cross-shaped columns. A good agreement was shown between the bearing capacity of nonlinear analysis and experiment. Load angle, eccentric distance, steel ratio，concrete strength grade and length-thickness ratio had been analyzed. The results show that steel ratio affects the
