| 摘 要： | In order to know the behavior of local nonuniform compression of fired shale perforated brick masonry with rectangular holes,the experimental study of 18 specimens with and without restriction at the end of beam under local compression was carried out.The failure modes and bearing mechanisms of specimens were researched and analyzed,the integrity coefficient of local compression stress figure was deduced,at last,the theoretical and testing values of local compression bearing capacity were compared and analyzed.The results indicate that the bearing performance at the end of wall section under local compression behaves better than that on the fringe,the vertical cracks throughout the specimen on the fringe caused by local nonuniform pressure weaken the advantageous function of 'unloading by the interior arch',the effective supporting length calculated according to code for design masonry structure is partial to safety.These results and suggestions can be used in the design of bearing perforated brick masonry for reference.
