Study of Trapezoidal Shaped Retaining Wall with Varying Geometric Parameters
Abstract: AbstractRetaining walls play a critical role in the protection of structures from damage related to soil collapse, but many property holders are unconscious of just how integral these walls are to the overall health of their property. Properly constructed and well maintained retaining walls not only mitigate soil erosion and wash-out after excavation, but also keep soil from collapsing. Soil collapse can put your structure at risk for damage and …

REVIEW ON BIODEGRADABLE CONCRETE
Abstract: Concrete is one of the strongest construction materials used all over the world and usually considered as indestructible because of their longer service life as compared with the most constructional products. However, they can get destroyed for a variety of reasons including the material limitations, poor quality design and construction practices, as well as the hard exposure conditions. Degradation mechanisms of concrete often depend on the way potentially aggressive substances …

Performance of Offshore Steel Jacket Platforms under Near-source Ground Motion Type Pulses
Abstract: Behaviour of jacket type offshore structures under ordinary ground excitations has already been addressed by a number of researchers. However, their performance under near-source ground excitations has not been particularly addressed in the literature. Records from recent earthquakes, such as the Kobe Japan (1995) and Chi-Chi Taiwan (1999), have revealed that the dynamic excitations in near-source are dominated by a large, narrow band and long period pulse caused by rupture …
