RELATION AMONG DIFFERENTIAL SETTLEMENT TROUBLES OF DETACHED HOUSES, INCLINATION ANGLE AND DISTORTION ANGLE

With regard to restoration of detached house foundation, the relation among inclination angle, distortion angle, and the degree of trouble was analyzed trough the actual condition survey and the settlement tests of full-size houses. Inclination angle related to difficulties on use and function, and distortion angle related to structural difficulties such as cracking need to be clearly distinguished. Though the recognition of inclination angle through the analysis results is just above approx. 4/1000, damages are caused even by a slight distortion angle and are gradually progressed. Each threshold angle (standard) is considered to be 6-8/1000 for inclination and 5/1000 for distortion.
