| Summary: | Rapid growth of population has led to increasing demands on fast, affordable
and quality housing. Nowadays, the construction industry in Malaysia has shifted
from conventional method system towards Industrialized Building System (IBS).
New technology investigation has been carried out to study the structural behavior of
Precast Lightweight Foamed Concrete Sandwich Panel or PLFP as a load bearing
wall system by previous researchers. In view of this, an experimental study is carried
out to investigate the behavior of vertical connection for Precast Lightweight Foamed
Concrete Sandwich Panel (PLFP). In this study, eight specimens comprised of plane
surface connections and one panel as control without connection is cast and test
under flexural loading until failure. The material used is foamed concrete with
density1700 – 1800 kg/m2 as the overall fill and mortal as the connection in-fill. The
objective of this study is to determine the load capacity and behavior of the
connected panel with different length over depth ratio (aspect ratio of 0.83, 1.25 and
2.5). The behavior of the connection is studied through their load-deflection
characteristic upon loading, load capacity, mode of failure and strain distribution.
The relationship between aspect ratio and behavior of the panel were also observed.
It was found that the higher aspect ratio, the more critical flexure failure at the
connection occurred. The load capacity of the panel reduces by 30 to 60 percent of
load with declination aspect ratio from 0.83 to 2.5. |
