AN EXPERIMENTAL STUDY ON THE LOAD CARRYING CAPACITY OF STEEL PIPE BEAM SUPPORTED BY COVERED PIPES

Abstract

This paper presents an experimental approach on the load carrying capacity of steel pipe beams supported by covered pipes which are adopted in the newly developed plane grid type check dam. The merits of a covered pipe are rapid construction, easy maintenance and increase of structural safety. However, the load carrying capacity of steel pipe beam supported by covered beams is not known yet so far. Therefore, the static loading test is first conducted to investigate the relationship between load and deformation of a steel pipe beam supported by covered pipes. Second, the test results on the load carrying capacity are compared with the ones by the current design formula for a steel fixed pipe beam.
