Paper Title:
Mechanics Characteristics and Failure Criteria of Concrete Confined by Lateral Stress after Suffering Cycles of Freezing and Thawing in Seawater
  Abstract

Biaxial compressive tests of plain concrete specimens suffering 0、25、50 and 75 cycles of freezing and thawing respectively in 3.5% sodium chloride solution imitated seawater were completed under four lateral constant stress rates. The tests were completed by using the large static-dynamic triaxial test system for concrete in the State Key Laboratory of Coastal and Offshore Engineering, Dalian University of Technology. The biaxial compressive strength and deformation characteristics of concrete confined by lateral stress after suffering corrosive cycles of freezing and thawing were studied in a systematic way. On the basis of the tests, the failure criterion of concrete subjected to constant lateral compressive stress after suffering corrosive cycles of freezing and thawing was established in the stress-strain system. The conclusions can provide the testing and theoretical basis for deeper study of the concrete construction subjected to biaxial compressive combined loads in northern cold region or influenced by corrosive cycles of freezing and thawing nearby the coastal and offshore area.
