Abstract

Local compression is a normal case in civil engineering.In order to have a further research on the local compression behaviors of concrete-filled steel tubular members with square sections, 28 axially loaded members under local compression were studied.Local compression tests of plain concrete and bearing strength tests of CFST were done simultaneously as a comparison, push-out tests were also carried out for bond strength.Based on the test results, the main factors were studied, and a method for bearing strength calculation was initially proposed.
- concrete-filled steel tubes,
- local compression,
- local compression area ratio,
- steel ratio,
- size effect
