Untersuchungen über das Tragverhalten von Übergreifungsstößen geschweißter Betonstahlmatten aus Betonrippenstahl unter Schwellast

Abstract

This article describes the results of tests for investigation of the behaviour of overlapped splices of welded reinforcing steel mats from ribbed reinforcing bars. The tests were intended for a verification of the specification laid down in DIN 1045. After a description of the test specimens of the materials used and of the test procedure, the results are explained. The area of the lapped splices and the areas outside the overlapped splices are dealt with separately. From the test results is derived a proposal for dimensioning of overlapped splices.
