POOR FLEXURAL REINFORCEMENT PLACEMENT FACTOR ON THE PERFORMANCE OF CONSTRUCTED DRAINAGE SYSTEM.
Journal Title: International Journal of Advanced Research (IJAR) - Year 2018, Vol 6, Issue 12
Abstract
Constructional implementation of good structural design that will translate to the require safety and design economy needs good workmanship. Previous structured studies showed that poor workmanship quality would significantly reduce the serviceability reliability and inadequate checks on constructional control resulted in over 90% of project failure. The statistics are worrisome and challenging. No doubt, flexural reinforcement placement at its designated (tensile or compression) place plays a very important in achieving both the strength requirement and satisfying the serviceability condition. However, a case for haphazardly placed flexural reinforcement for lined-drainage during construction of township road that suffers frequent road embankment failure needs further investigation beyond a structured questioner on the effect of poor workmanship. Hence, this study attempts to access the impact of poor placement of flexural reinforcement at its designated zone primarily due to workmanship error using numerical analysis software. The finding reveals that poor flexural reinforcement placement at its design zone will lead to unnecessary stress built-up and this has far-reaching consequences on the performance of the constructed facility. It was found also that a unit change in flexural reinforcement placement position in the tensile zone towards the neutral axis position result in about 3.1% surge in deformation value.
