• Fifteen composite PVC encased concrete wall specimens were tested at UTS Tech Lab. For flexural testing, three-point bending test on a three-metre span was chosen. Using BarChip 48 leads to 43.5% strength improvement and 25% stiffness enhancement. walls exhibit 2.4 % more capacity than conventional reinforced walls. without rebars are suitable for sway-prevented structures. Composite provide ...

In this study, optimization is carried out to find the optimized design of a foam-filled column for the best Specific Energy Absorption (SEA) and Crush Force Efficiency (CFE). In order to maximize SEA, the optimization gives the value of 2.3 for column thickness and 151.7 for foam length. On the other hand to maximize CFE, the optimization gives the value of 1.1 for column thickness and 200 for...

Liquefaction is a disaster that can damage building infrastructure. This all too common in granular sandy soils. due to the subsidence and instability of soil when subjected shocks such as earthquakes. For this reason, mitigation efforts are needed reduce risk liquefaction. study will compare effectiveness influence micro-pile, stone column, densification methods on soils at Central Java PLTU s...
