An innovative concrete-steel structural system allowing for a fast and simple erection

Autor: Franck Palas, Piseth Heng, Pisey Keo, Clemence Lepourry, Hugues Somja

[EN] In usual concrete buildings, medium to long span slabs can only be achieved by using prestressed beams. However, these elements are heavy, making their handling expensive; the cladding of these beams to vertical elements creates several difficul
