Masonry Building - Influence of Change of Load on Its Defects

This paper deals with the investigation of defects of three-story masonry building due to improper design and infringement of the technological procedures during the construction of building. Various cracks in load-bearing masonry walls and also the cracks in masonry partition walls are significant defects. The main reason is usually improper design of load-bearing elements of the structure (dimensions of masonry walls and partition walls, reinforcement or thickness of RC ceilings, bracing of the whole structure, straining beams) and a non-uniform settlement of building. Therefore, a plate of typical floor and non-uniform settlement of selected building were assessed in this paper. Description of the structure, applied loads, considered soil-structure interaction in the computing model, and examples from the similar structures are mentioned. Obtained results are analyzed and recommendations in similar cases for planning engineers and site managers are mentioned.
