| தொகà¯à®ªà¯à®ªà¯: | Traditional cast in situ construction has been a common practice adopted by
building industry in this country. This process could not meet the huge demand on
affordable housing which is the major issue now because it requires large number of
workers, massive casting and erection work, and longer construction time. As a
solution to this, a precast system needs to be innovated as an alternative to this
traditional system. Current research has been focusing on precast panel system made
of conventional concrete. Therefore, this research investigated the structural
behaviour of single and two connected Sandwiched Precast Foamed Concrete Panel
(PLFP). Eight single PLFP and three sets of connected PLFP panels were cast using
foamed concrete as the wythe and polystyrene as the core layer. The panels were
strengthened with steel bar reinforcement embedded in both wythes which were
connected to each other by the steel shear truss connectors. Single PLFP panels were
tested under axial load while connected PLFP panels were tested under flexural load
test. The results were analyzed in term of the panel’s ultimate load, crack pattern
and mode of failure, load-deflection and load-strain profiles. It was found that the
ultimate load recorded in single PLFP panels from experiment showed good
agreement with the values from previous research. Connected PLFP panels were
able to sustain slightly lower ultimate load compared to single PLFP panel. The
percentage difference between these ultimate load values is about 14%. The value of
ultimate load recorded for single and connected PLFP panels were 171 kN and 147
kN, respectively. For both single and connected PLFP panels, it was observed that
ultimate load, crack pattern and failure mode, load-deflection and load-strain profiles
were significantly influenced by the panel’s slenderness ratio. Finite element
analysis using LUSAS software is also carried out to study the effect of slenderness
ratio on ultimate load. It was observed that the difference value between FEM and
Experimental for single and connected PLFP panels are in a good agreement which
recorded 4.5% and 5.8%, respectively. |
