开洞口粉煤灰砖墙和粉煤灰砌块墙体的试验研究

Test research on the walls with openings made by fly ash bricks and fly ash blocks

通过两片带洞口约束梁柱蒸压粉煤灰实心砖墙和两片粉煤灰砌块墙的试验研究,对比分析了墙体的破坏特征、承载力、滞回特征、延性、耗能等方面的差异。试验结果表明:蒸压粉煤灰实心砖墙的强度、刚度、耗能能力都要优于粉煤灰砌块墙。

Two fly ash brick walls and two tly ash block walls with openings and RC beam-column along the wall perimeter were tested, and then the differences between two type of walls in the failure characteristics, bearing capacity, hysteresis curves, ductility and energy dissipation were analyzed. Finally the experimental conclusion was produced, that is：the strength, stiffness and the energy dissipation of fly ash brick walls is better than those of fly ash block walls.
