Material Testing and Evaluation of Steel Mechanical Properties for Classification of Steel Grade of Existing Civil Engineering Structure

Material Testing and Evaluation of Steel Mechanical Properties for Classification of Steel Grade of Existing Civil Engineering Structure

Peer-reviewed article not indexed in WoS or Scopus

The paper is generally focused on the determination and evaluation of yield and ultimate strengths of structural steels, not only current materials but also materials of existing steel structures when the properties are unknown and no material certificates exist. The attention is paid i.a. to the testing and evaluation of steel strengths, especially from the viewpoint of the statistical elaboration of material test results aimed to obtain strength values leading to the reliable structural design [3], in the meaning of general rules according to the European Standards for structural design of civil engineering constructions. The paper deals with actual yield and ultimate strengths obtained using material tests and with characteristic and design strengths based on the test results evaluation versus nominal and design strengths given by European Standards which are used for the structural design in the usual cases when steel grade is known. But in the case of existing structures, very often no information about the material exist that actual values of steel properties shall be determined using material tests and their statistical elaboration to obtain such values of steel properties which lead to the reliable structural design
