Abstract
In focus are special cases of distortion of buildings when heavy structural deformations were visually observed though instrumental monitoring showed low strain values. The experimental laser scanning of such deformations exhibited complex deformation patterns in horizontal planes of buildings. Aimed at defining the causes of the nonlinear deformation of buildings and structures and preventing relevant accidents, the integrated monitoring technology is offered based on taking account of stress-strain state and block structure of the building-underlying rock mass.
