Abstract

Torsional behaviors of col- formed steel beams are investigated for the webs which are filled by polypropylene. Four I and U profile beams filled with polypropylene were manufactured and tested. In the study, two specimens U100 and two specimens I100 profiles with 1.5 m length and 1.20 mm thickness and thin-walled cold-formed steel profiles were used. The aim of this study is to investigate the torsional behavior of the composite material formed by pouring the polymer material into the U and I profile molds after homogenous pulping. A total of two groups of samples will be obtained: empty cold-formed steel profiles and waste polymer. In this study, finely ground waste and/or raw PP (polypropylene) was used as filling material. The polypropylene is not only improved the torsional behavior strikingly; but also give a way on environmental profit for waste recycling.
