This paper explores some of the aspects of embedded retaining wall design, in particular the interrelationship between system uncertainty and the use of factors of safety in the various design procedures. System uncertainty reflects the mismatch between idealised retaining wall behaviour and what is observed in practice. This feature is modelled using the concept of fuzzy sets where the degree ...

The main objective of this study is to evaluate the workability of fresh portland cement concrete while it is still in the mixing truck by determining fundamental rheological parameters (plastic viscosity and yield stress). Nine concrete mixtures with different values of yield stress and plastic viscosity were tested in a concrete truck. The measurements made with the truck were based on the ty...

The columns of frame structures are the key load-bearing components and the exterior columns are susceptible to attack in terrorist blasts. When subjected to blast loads, the columns would suffer a loss of bearing capacity to a certain extent due to the damage imparted which may lead to their collapse and even cause the progressive collapse of the whole structure . The concrete-filled steel col...

Designing advanced methods of corrosion protection and increasing the bearing capacity pile foundations on saline clayey soils is a priority geotechnical task in Kazakhstan. The formation suffusion-resistant waterproof shell was achieved by silicatization borehole before concreting, installation mold into impregnation sodium silicate solution space between soil under pressure. After coagulation...

• 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 ...
