Cracking in non-load-bearing internal partition walls is a serious problem that frequently occurs in new buildings within the short term after putting them into service or even before completion of construction. Sometimes, it is so considerable that it cannot be accepted by the occupiers. The article presents tests of cracking in ceramic walls with a door opening connected in a rigid and flexible way along vertical edges. The first analyzes were conducted using the finite element method (FEM), and afterward, the measurements of deformations and stresses in walls on deflecting floors were performed on a full scale in the actual building structure. The measurements enabled to determine floor deformations leading to cracking of walls and to establish a dependency between the values of tensile stresses within the area of the door opening corners and their location along the length of walls and type of vertical connection with the structure.
非承重内隔墙开裂是一个严重问题，在新建筑投入使用后的短期内甚至在施工完成前就经常出现。有时，裂缝非常严重，以至于居住者无法接受。本文介绍了对带有门洞的陶瓷墙沿垂直边缘进行刚性和柔性连接时的开裂测试。首先使用有限元方法（FEM）进行分析，然后在实际建筑结构中对挠曲楼层上的墙体变形和应力进行了全尺寸测量。这些测量能够确定导致墙体开裂的楼层变形，并确定门洞角部区域内拉应力值与它们沿墙体长度的位置以及与结构的垂直连接类型之间的关系。
