Abstract
This paper studies the ultimate carrying capacity and structural behavior of precast lightweight foamed concrete sandwich panel (PLFP) with double shear truss connectors under axial and eccentric loading. Eight small scale PLFPs with various slenderness ratio were casted and tested. Ultimate load carrying capacity, load deflection profile, surface strains and crack pattern were recorded and analysed to compare the PLFP structural behaviour under two different loading conditions. Results obtained showed that PLFP was able to sustain higher axial loading compared to eccentric loading. PLFP with lower slenderness ratio achieved higher ultimate load carrying capacity compared to higher slenderness ratio. Comparison of deflection profiles also proved that PLFPs under axial loading achieved higher ultimate carrying capacity and compositeness reaction compare to PLFP under eccentric loading.
