砌体结构裂隙的成因分析与控制----外文翻译.docVIP

Body of structural cracks in the cause of analysis and control Summary: Control structure of rifts is a relatively simple and common problems, but it is a door and the mechanics and regong, waiting for material to the professional knowledge is very close relations of comprehensive and complex subject and are building in order to ensure the quality of the important link to be neglected. In the field and at present the domestic is no uniform criteria and indicators to follow. the general theory and practice from years of experience, which causes structural cracks in the analysis, the fissures and control measures to strengthen methods. Keywords: Ago gapped, A mechanism, Control measures 1. Survey In multi-storey buildings in the structure of rifts have much extra thickening, and cracks in the time depending on the building, some in the morning, some in the night, but often happened in the new house in 1 to 3 year, Stitching width, wide three, Two or more,Formed in severe cases Through Structural cracks in the body has a universal problem, and it only the building, reduce the architectural features and use year control, and is also of great disservice to the vibration, especially in commercial today, this problem has become a universal concern of the developers and the residents, therefore, how to control the physical structure of the cracking problem is the extra thickening in the engineering personnel of a new subject. 2. Break causes and type Produce crevice of the causes are maniffold, together with the two sides of the load ： a （ include static load ） changes, the fissures and the deformation of the fracture （ the uneven temperature changes, expansion and sank down, or shape of a stress fracture ）. in the structure of the civil construction of a fracture in the most is the deformation, the temperature change is the main factor causing cracking ago，The bricks to build the expansion of the line of reinforced concrete, and the expansion is therefore when the tempe
