Structural behaviour of precast lightweight foamed concrete sandwich panel (PLFP) with double shear truss connectors under eccentric load: preliminary result

摘要

Recent years in Malaysia, precast concrete sandwich panel gained its popularity inbuilding industries due to its economic advantages, superior thermal and structural efficiency. Thispaper studied the structural behaviour of precast lightweight foamed concrete sandwich panel(PLFP) with double shear truss connectors under eccentric load. Preliminary results were analysedand studied to obtain the ultimate load carrying capacity, load-deflection profiles and straindistribution across the panel thickness at mid depth. The achieved ultimate load carrying capacity ofPLFP due to eccentric load from the experimental work was compared with values calculated fromclassical formulas (if it is more than 1 comparison) developed by previous researchers. Preliminaryresults showed that, the use of double shear truss connectors in PLFP was able to improve itsultimate load carrying capacity to sustain eccentric load and achieve certain compositeness reactionin between the wythes.
