Evaluation of Hydraulic Performance: A Case Study of Etana Small Scale Irrigation Scheme: Wolaita Zone, Ethiopia
Abstract: The conventional furrow irrigation system is inherently inefficient in wolaita zone, while the suboptimal management and operation (inflow discharge and cutoff time) are considered as one of the main reasons for satisfactory hydraulic performance. Addressing these issues, the furrow irrigation system which is only practiced in the study area was evaluated on three fields under routine farmer management in wolaita zone. The study consisted of field experiments and simulation modeling. …

Prediction of Circular Frequency of Precast Concrete Piles with Distributed Mass by Resonance Moment–Displacement Approach
Abstract: This paper presents the results of circular natural frequency of single piles from critical buckling load by resonance moment-displacement approach. The support end conditions considered are pinned-pinned, fixed-fixed, and fixed-pinned respectively. It was assumed that resonance moment occurs when the bending moment diagram is made equal to zero at the supports while the resonance displacement is the sum total deflections resulting from the system reduction to an equivalent pinned-pinned system. …

Nonlinear Pushover Analysis of RC Frame Considering SSI Effect: A Review
Abstract: It is the need of modern era to go for the safe, reliable and economic structure design with special reference to seismic response of the structure. The classical methods which are based on elastic analysis are not able to predict the structural behaviour under the seismic forces. On the other hand the Pushover Analysis (POA) gives more reliable results. The POA is a static –nonlinear analysis. In this method the …

Effects of Reinforcing Elements in Soil Reinforcement
Abstract: The inclusion of reinforcing elements in a soil mass improves its geotechnical properties. The principle behind soil reinforcement is that the reinforcing elements absorb the tensile load and shear stress within the reinforced structures and hence prevent the shear failure and settlement. The friction developed between the interface of soil and reinforcing element improves the properties of soil. Different types of natural and synthetic fibers have been used in various …

Prediction of Compressive strength of Periwinkle Shell Aggregate Concrete Using a Quadratic Polynomial Function
Abstract: In this study, a mathematical model is developed to predict the compressive strength of normal concrete made with periwinkle shell as coarse aggregate using a quadratic polynomial function. The response function is expressed as a multivariable function of the proportions of the component materials (water, ordinary Portland cement, sand and periwinkle shell). A total of thirty experimental runs were used to demonstrate the applicability of the mathematical model developed. The …

A Study on Self Compacting Concrete using Portland Pozzolana Cement
Abstract: Self-compacting concrete (SCC) is a type of highly flowable concrete that fills each and every corner of congested formwork without the need for mechanical vibration as it is placed by means of its own weight. Generally, the SCC is prepared by using Ordinary Portland Cement (OPC) with mineral and chemical admixtures. Portland Pozzolana Cement (PPC) itself contains some amount of fly ash, thus given the motivation to prepare the SCC …
