Roberto Scotta is Assistant Professor of Structural Design at the Department of Civil, Environmental and Architectural Engineering (DICEA) of the University of Padova (Italy) since 2006. He was teacher of the courses “Precast Structures”, “Structural Design 2”, “Structural Construction 1”, and currently “Structural Construction 2” and “Timber Structures”. The topics covered in his research activity range from the non-linear behaviour of structures, durability of reinforced concrete, design and seismic verification of concrete, masonry and timber buildings, optimization of steel-concrete structures, development and optimization of new construction technologies.

Predavanje: "Concrete buildings cast into woodchip - cement formworks"

ABSTRACT

Analisys of  the load-bearing concrete walls – with or without reinforcement – cast into woodchip-cement formworks. This type of wall differs from those traditionally used in Italy, whereas it is more common in northern European countries, such as Austria and Germany, where it was originally developed to meet the increasing demand for insulation performance of the buildings. To comply with the latest regulations in terms of energy consumption in buildings and acoustic requirements, the construction industry continues to show a growing interest in the constructive material analysed in this presentation. From a structural point of view, since the contribution of the formwork to the global strength and stiffness of the system is negligible, the concrete wall can be schematized as a grid composed of vertical columns and horizontal ribs, with  possible addition of steel reinforcement. The high strength and dissipative capacity that this system can assure – especially with the use of reinforced concrete (RC) – are a result of the high internal redundancy. However, it cannot be considered as a RC structure, since the requirements for confinement of concrete, guaranteed in the traditional RC structures by the stirrups, cannot be fulfilled, nor can it be considered in the category of ordinary masonry, formed by artificial elements with interposed mortar. The design and verification of the wall panels in question require therefore a specific analysis. In some respects, their behaviour can be assimilated to that of reinforced masonry, from which it is possible to borrow some executive and design criteria.
