Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

This chapter explores an improved method for detecting multiple damages in I-section steel beams using mode shape curvature changes. The study employs finite element modeling to simulate beam structures and analyzes the impact of damage on the beam's vibration characteristics. The method focuses on using mode shape data to identify damage locations, with a proposed damage threshold to determine the extent of damage. The study introduces three damage detection indices to assess the accuracy of the method. The results demonstrate high reliability in identifying both single and multiple damage zones. The chapter also discusses the importance of selecting the appropriate number of vibration modes for accurate damage detection. The study concludes that the improved mode shape curvature change-based method is effective in identifying the presence and location of damages in steel beams. The chapter provides valuable insights into the practical application of this non-destructive damage detection technique, making it a crucial resource for professionals in structural health monitoring and civil engineering.
