The primary role of Economic Load Dispatch (ELD) is for obtaining the most efficient operation out of an electrical power system generation network. The main objective of performing the ELD is to minimize the generator fuel cost. To solve the problem, Improved Particle Swarm Optimization (IPSO) algorithm is proposed in this research. There are two…
In power generation, one of main problems is how to meet related power demand continually and effectively. As known in field power operation, economic dispatch (ED) is one of the important problems in supplying load demand with minimum cost by summing the output of each generator. This research is trying to propose Lagrange with a…
The interferometric method measures water evaporation was conducted by opti-cal path shifting interferometry due to the change in the length of optical path. The height of water that dried up from the glass is equally valuable to the increased length of the light. Counting the number of sinusoidal fringes allowed us to calculate amount of…
This paper presents the mixing proportion of high-performance concrete (HPC) having compressive strength over 80 MPa. This type of concrete comprises of almost con-stituents with fine particles and often having additional steel fibers in the mixture of HPC. The HPC showed excellent properties such as high compressive strength, high stiffness, improved toughness and durability compared…
The paper presents the results of reinforced concrete beam tests in crack resistance, deformability under long-term loading. The study allowed evaluation stiffness and cracks resistance of reinforced concrete beam using pre-organized cracks and conventional reinforced concrete beam under long-term loading. The results of deflection of rein-forced concrete beams with pre-organized cracks under the action long-term…
Composite reinforced concrete (RC) elements with ultra-high performance con-crete (UHPC) subjected to blast loading was conducted through numerical modelling. The interfacial bond characteristics were also considered into the model. The blast model was validated using test results in available literature. Behavior of the UHPC layer attached onto RC elements was numerically observed. Simulation results showed…
Reinforced concrete (RC) jacketing of RC columns is used to increase the load-carrying capacity of RC columns with insufficient strength. The method of RC jacketing is an easy and cost-effective method. The confinement action is influenced by the stirrups in concrete core, stirrups in RC concrete jacketing, the thickness of RC jacketing, and the strength…
This present study addresses an assessment of effects on punching shear behavior and capacity of reinforced concrete (RC) slabs. The review on the punching shear capacity of the RC slab-column connection were conducted based on well-known literature. From the assessment, the concrete strength including concrete with steel fibers contributes sig-nificantly in the punching shear strength…
In many countries, and especially in Cambodia, there are many old structures, such as buildings and bridges, which are long-lived and will continue to deteriorate due to problems related to reinforced concrete (RC). One way to be able to delay or even prevent debt default is by anchor FRP. The experimental study of the effectiveness…
this case study presents the analysis of basic wind speed and serviceability evaluation of tall rein-forced concrete buildings under wind and earthquake in Phnom Penh. The objectives are to examine the basic wind speed in Phnom Penh and to compare the serviceability with earthquakes. First, the wind data collection from Phnom Penh Airport was analyzed…
