Prestressed hollow core slabs supported on beams. Finnish shear tests on floors in 1990-2006
The effect of flexible supports, i.e. reduction of the shear resistance of the hollow core slabs due to deflection of the supporting beams, has been experimentally studied since 1990. The results and analysis of ten tests carried out by VTT, Finland, have been published previously. Due to these tests and parallel tests performed elsewhere it has become clear that the reduction of the shear resistance has to be taken into account in design. In 2005, a research project dealing with the effects of flexible supports was started at RWTH, Aachen. New floor tests were performed, but the results of the former Finnish and German tests were also considered. As a part of the project, the test arrangements and results of twenty Finnish floor tests in 1990-2006 have been elaborated and published in this report. The aim has been to provide experimental data which can be referred to when writing scientific papers or when developing and standardizing European design rules. No analysis of the results is presented. The aim has also been to make the data so complete that there is no need to read the original test reports, five of which have been written in Finnish. Some tabulated characteristics of the tests are given on the first page. The rest of the report is divided in 20 Chapters, each including the results on one floor test and the related reference tests. The German test results are available at http://www.imb.rwth-aachen.de/Weitere-Informationen/ (Titel "Zum Tragverhalten von Spannbeton-Fertigdecken bei biegeweicher Lagerung").
