Spannglass Beams - Glass Beams with Post-tensioned Reinforcement

Glass beams may be loaded to a higher degree by reinforcing them and applying the approach from reinforced concrete design. Thus, a post-tension may be added as well. Those Spannglass Beams are under investigation during a research project at the Institute of Building Construction. Four different reinforcement layouts using filigree cables from stainless steel were investigated in Spannglass Beams made from heath strengthened and fully tempered glass. The results from four-point-bending tests are analyzed in order to estimate the potential of those novel constructions.
