【 摘 要 】

The present paper presents the results of testing of steel-tube confined-concrete structural elements with polymer composite casings under various loading patterns. The tests were carried out for structural elements of different static patterns under static and low-cycle loads. Test samples were produced during proving the technology of manufacturing of such casings, so they have a certain number of defects. According to the tests, the reliability and durability of steel-tube confined-concrete structural elements were evaluated. Test results of samples with different braiding angles were compared, and the selection of the braiding angle of the pre-form for the second batch of tests was substantiated. A conclusion was made on the possibility of using such structures in transport construction as main load-bearing elements of transport structures; in particular, in construction of small road bridges.
