STRUCTURE MEMBER CONTROL AND DIAGNOSTICS METHOD

摘要

FIELD: building, particularly to control building structure member deformation. ^ SUBSTANCE: method involves embedding optical light guides in structure members; connecting light guide ends with each other to form at least one serpentine arrangement; linking light source and light receiver correspondingly to the first and the second ends of the serpentine arrangement; measuring optical power of serpentine arrangement and determining the first reference value from above measurement; measuring optical power of each light guide and determining the second reference value from above measurements; performing the third optical power measurement and comparing thereof with the first reference value; periodically performing the third measurement to find out structure member destruction. If the first reference value exceeds value determined during the third measurement one can judge that the structure member destruction has occurred. Then the forth optical power measurement of each light guide is executed and destructive light guides are discovered in light guide cross points. ^ EFFECT: increased accuracy, reliability and longevity of structure member destruction measurements. ^ 2 cl, 5 dwg
