8. Seismic resistance
Seismic resistance is a key consideration in the design and construction of buildings in earthquake-prone areas. Coreslab structures are well-suited for seismic resistance due to the inherent properties of precast concrete panels.
Precast concrete panels are manufactured in a controlled environment, which ensures consistent quality and strength. The panels are also reinforced with steel rebar, which further enhances their strength and ductility. This combination of strength and ductility makes coreslab structures able to withstand the lateral forces generated by earthquakes.
In addition, the precast concrete panels are connected to each other using a variety of methods, including grouted connections and post-tensioning. These connections allow the panels to work together as a system to resist seismic forces. The connections also provide flexibility, which allows the structure to dissipate energy during an earthquake.
The seismic resistance of coreslab structures has been demonstrated in numerous real-world earthquakes. For example, coreslab structures performed well in the 1994 Northridge earthquake, the 1995 Kobe earthquake, and the 2011 Tohoku earthquake. In each of these earthquakes, coreslab structures were able to withstand the strong ground motions without collapsing or suffering major damage.
