Hurricane proof buildings – An innovative solution using prefabricated modular wood-concrete-composite elements

摘要

Recent work at the University of Applied Sciences in Wiesbaden / Germany has indicated that wood-concrete-composite systems develop a strong position against contemporary designs like reinforced concrete and steel-concrete composite systems. In order to improve the range of applications this research was conducted to analyze the response of continuous wood-concretecomposite systems under hurricane loading conditions with wind speeds up to 250 mph (400 km/h). The wood-concrete-composite building (wcc-building) system is based on individual module components. These prefabricated rib-shaped elements consist of wooden beams inner connected with a concrete slab. Both cross sections are connected through a single row of HBV-shear connectors. The wcc-building system allows for a cost efficient hurricane-proof design. It furthermore provides enormous advantages over contemporary American and European building systems under seismic loads. The study shows structural details of prefabricated wcc-elements as well as a design proposal.
