For many years, fibre cemboard has been widely used in the construction industry. This material advantages, including a long-life span, ease of installation and low maintenance, which can reduce cost maintenance. However, due to its limitation being unable support heavy loads, it is only suitable for lightweight floor system. Therefore, panel introduced. Basically, consists several layers that ...

Due to the extensive use of composites in various industries and the fact that defects reduce ultimate strength and efficiency during operation, detection of failures in composite parts is very important. The aim of this paper is to use Acoustic Emission (AE) non-destructive method in four-point bending test of carbon/epoxy composite to analyze and examine the failure mechanisms. This method is...

Due to permanent ground deformation (PGD) such as earthquakes and liquefaction, water supply pipes connected joints may experience rotation deflection through losing its function complex contamination. Since the specifications of are different in each country, evaluating difficult manage functional maintenance network system. In this study, two metallic three non-metallic pipe were selected com...
