摘　　要：为研究节能砌块内置钢筋混凝土墙板的破坏特征和受压性能,进行了4个1/2模型节能砌块内置钢筋混凝土墙板偏心受压试验,分析了各试件的破坏过程、破坏形态及承载力、协同工作性能。研究结果表明:节能砌块与内置钢筋混凝土之间协同工作性能良好;随着偏心距的增大,试件破坏由小偏心受压逐渐变为大偏心受压,破坏荷载逐渐降低,符合偏心受压构件的破坏规律;所有试件的破坏均属于材料破坏,没有发生平面外失稳破坏;按GB 50003—2011计算结果与试验结果吻合良好,能够满足工程实际要求。In order to research the failure characteristics and compression performance of energy-saving block with reinforeed concrete input walls,four pieces of 1/2 scale energy-saving block with reinforced concrete input walls are studied experimentally under eccentric compression. Failure processes,failure modes and bearing capability,cooperative working action of various specimen are aualyzed. The results showed that energy-saving block and reinforced concrete can work well together. With increasing of tire eccentricity, the failure modes change from small eccentric compression to large eccentric compression, and the failure load decreas- es,these phenomena coincide with the failure of structures eccentric compression. All the walls failure due to material damage,out- of-plane axial bending failure doesn＇t occur. According to the current specification calculation results are in good agreement with those obtained with the test results,and these results are good enough to meet the requirement in engineering praetice.
