During this stage, a common approach is to crete beams results in a ductile response and allows evaluate the effect of broken layers in the glass section, for the design of structures that are more reliable and which may result in eccentric loading by the tendon efﬁcient. Therefore, this approach has been adapted and introduce additional bending about the minor axis. to structural glass producing reinforced and post- Thus, the novel structural design may cause an early tensioned glass beams.
