A PRECAST REINFORCED CONCRETE SYSTEM WITH CONTROLLED DYNAMIC PROPERTIES

JIŘÍ WITZANY, TOMÁŠ ČEJKA, RADEK ZIGLER


Abstract

The precast reinforced concrete system with controlled dynamic characteristics allows, together with demountability, an efficient optimization of a load-bearing system’s response to external dynamic and static loading effects and impacts. The essential elements of the system are the joints of load-bearing reinforced concrete precast units with high ductility allowing the absorption of dynamic energy and the optimization of the load-bearing system’s response to technical as well as natural seismicity. Another significant feature of such joints is their ability to eliminate outside noise (e.g., traffic, building activity, industrial activity) below the threshold of hearing; this improves the quality of the interior environment and allows land development in areas with increased noise levels, traffic, etc. The system may also be analogically applied in areas with poorer foundation conditions, in areas with underground traffic, in undermined areas, and in areas with high seismic risks.
