［摘要］通過試驗研究了開槽蒸壓灰砂磚砌體的抗剪強度，試驗和研究分析表明：在磚的大表面開槽后，明顯地提高了蒸壓灰砂磚砌體的抗剪強度，其中開斜槽對蒸壓灰砂磚砌體抗剪強度值提高最大，并基于開槽方式變化的對比研究提出了更合理的開槽方式。試驗數據分析表明，開槽蒸壓灰砂磚砌體抗剪強度值可采用現行砌體規(guī)范的抗剪公式和規(guī)范規(guī)定的蒸壓灰砂磚或粘土磚砌體抗剪強度值。

Abstract:The shear strength of grooved autoclaved lime-sand brick masonries was studied through experiments. The experimental results illustrate that the shear strength of autoclaved lime-sand brick masonries increases rapidly with the grooving on surface of autoclaved lime-sand brick masonries. Furthermore, oblique grooves on bricks contribute most on improvement of shear strength of autoclaved lime-sand brick masonries. A more reasonable grooving method was proposed based on comparison and research on grooving method change. The experimental results indicate that the shear strength of grooved autoclaved lime-sand can refer to the formula of shear resistance of current code of masonry structures and the shear strength of autoclaved sand-lime brick and clay brick masonries ruled by the code.
Keywords:autoclaved sand-lime brick; grooving; masonry; shear strength
