Stress field analysis of hollow brick anchored by new expansion bolt
The heat transfer performance of hollow bricks with two kinds of thickness under the condition of vertical aperture was studied by steady comparison method.
Through experiments, the shear strength of concrete hollow brick masonry has been researched in this paper.
