Abstract
This study examined the flexural response of thermal-meta precast concrete panels developed for high-insulation and nonflammable exterior building materials as an alternative of the conventional sandwich panels. The main parameters investigated were the connection type at the panel-to-base interface and span continuity. The conventional splice sleeve method and welding connection were considered at the panel-to-base interface for each one- and two-span panels. The panel section was composed of top and bottom concrete layers and inner thermal-meta layer using honeycomb paper, producing the overall depth of 350 mm. The top and bottom concrete layers were reinforced using deformed bars with a diameter of 10 mm. Test results showed that the investigated panel-to-base interface can be considered as fixed-end condition from the crack distribution and comparisons between experiments and predictions for the initial flexural crack strength and the ultimate flexural strength. The displacement ductility ratio of panel specimens satisfied the design requirements derived from seismic design provision of KBC 2016. Overall, the developed precast concrete thermal-meta panels exhibited a good flexural resistance and ductility, achieving the grade one for strength classification specified in KS F 4736.
