摘要:

进行了6根3D打印结构柱和3根普通钢筋混凝土柱的偏压试验，分析了3D打印结构柱在不同偏心荷载作用下的破坏特征、挠度与承载力，并与普通钢筋混凝土柱进行对比.试验表明：3D打印结构柱与普通钢筋混凝土柱的破坏模式类似，但承载力降低10%~20%；跨中最大挠度随着偏心距的增大其增幅略微增大.所得试验结果可为3D打印结构柱的实际应用提供依据.

Abstract:

Six 3D printing structural columns and three common reinforced concrete columns were tested under eccentric loading. The failure characteristics, deflection, and bearing capacity of 3D printing structural columns and common reinforced concrete columns were compared and analyzed. Experimental results indicate that failure mode of 3D printing structural column is similar to common reinforced concrete column, the bearing capacity of 3D printing structural column decreases by 10%20%, and with the increase of eccentricity, the growth of maximum deflection is also increased.
