多功能混凝土空心砌块砌体受剪性能研究

Study on the behaviour of multifunction concrete hollow brick masonry under the shearing force

通过试验研究了多功能混凝土空心砌块砌体的抗剪强度。试验结果表明:多功能砌块采用了双排交错盲孔的孔型设计,提高了砌块和砂浆的有效粘结面积,大大增加了砌体剪切面积;砂浆的销栓作用有效的提高了砌体的抗剪强度;多功能砌块砌体的抗剪强度大大高于混凝土空心砌块砌体的抗剪强度。提出了多功能混凝土空心砌块砌体的抗剪强度计算公式。

Through experiments, the behaviour of multifunction concrete hollow brick masonry under the shearing force has been researched. The results show that multifunction concrete hollow brick with doublebank interleave blind holes causes to enhance the area of cohesion between brick and mortar and enlarge the shear area. Masonry shear strength will be raised effectively under the dowel action of mortar. And the masonry shear strength of multifunction concrete hollow brick is higher than that of concrete hollow block. Furthermore, the shear strength formula of multifunction multifunction concrete hollow brick masonry is proposed.
