In this article, the water entry problem of reticulated pounder including 4, 9, 16, 25 and 64 holes which are distributed with a matrix arrangement on the surface of the pounder, is investigated numerically and to model the interaction between the pounder and fluid, an explicit dynamic analysis was employed ... Read More In this article, the water entry problem of reticulated pounder including 4, 9, 16, 25 and 64 holes which are distributed with a matrix arrangement on the surface of the pounder, is investigated numerically and to model the interaction between the pounder and fluid, an explicit dynamic analysis was employed using the Eulerian-Lagrangian couple formulation available in the commercial finite element software Abaqus 6.14-2. The results of the numerical solution were validated by comparing and matching the numerical, theoretical and experimental results of the trajectory of a spherical projectile in the depth of water, including the shape of the air bubble formed and the pinch-off time and depth, which indicated the accuracy and application of the numerical algorithm used. The results of the current research showed that the 9-hole pounder reaches the model bed at a depth of 100 cm in less time than other pounders with different arrangement and number of holes. In 16- and 25-hole pounders, the ratio between the mass of the pounder and the area of the holes is unstable, and due to the decrease in the area of the holes, the effect of water resistance on the bottom of the pounder increases when it moves in its depth. The effect of increasing the mass of the pounder on reducing the duration of its immersion in the water depth is more evident in the 64-hole pounder. So that this pounder has a smaller area of holes compared to other pounders, it has more mass with smaller holes than other pounders, and despite the smaller dimensions of the holes and the increase in the life of the reticulated pounder, which is the factor that increases the resistance of the water entering the pounder floor, due to the large mass of the pounder, it overcomes the water resistance that is applied as an upward force on the bottom of the reticulated pounder, and the duration of its movement in the depth of the water is reduced from the moment it hits the free surface of the water until it reaches the model bed.

Read More Earned value management (EVM) is one of the most frequently applied methods in project management for the investigation of the performance and controlling of the temporal and cost progress of the project. Using its temporal and cost control indices, this method is capable of predicting the future status of the project in terms of time and cost. But, this approach falls short of taking the risk analysis and project’s variability into account. The primary goal of the present study is the conceptual and subjective combining of risk management and EVM and investigation of the effect of risk occurrence on the project’s objectives using the EVM indices. To collect the information on the theoretical foundations and study literature and study background, use has been made herein of the Persian and Latin books, articles, dissertations and information databases and questionnaire and interview have been the methods of choice for gathering the information pertinent to the scales and indices. Moreover, in order to identify and prioritize the risks, the perspectives of the sophisticated experts and managers in civil activities have been inquired and ANP and Super Decision Software have been the instruments of interest for information analysis. After analyzing and evaluating and prioritizing the risk, the risk management process has been applied along with challenging the dimensions and factors influencing the project’s prospective performance to offer the risk coefficient that was subsequently combined with the current EVM indices for increasing the accuracy and precision of the project goals’ estimation. A civil reconstruction project (central building project of Shiraz’s municipality) in progress was evaluated for applying and comparing this method. Finally, it was found that the occurrence of risk has a significant impact on the project's objectives and changes its time and costs, additionally, given the risk factor, deviation from the time and cost of the project can considerably decrease.

Read More The cycle of freezing and thawing is one of the damage factors of concrete in cold regions. For this type of damage, the air temperature must change to the point of freezing, melting. The concrete must be in contact with water or humidity, and the porosity of the concrete must be inappropriate. The progression of damage depends on the number of cycles, temperature during solidification, porosity of concrete and environmental conditions of concrete. In this research, the effect of adding early-breaking cationic emulsion bitumen on the durability and other characteristics of structural concrete was investigated by performing water absorption tests, concrete resistance against freezing, melting, permeability, concrete resistance against chlorine ion penetration by electrical conductivity method. For this research, four mixing plans, one mixing as a control and three mixing with the addition of 2, 4 and 6 percent by weight of emulsion bitumen compared to the weight of cement were prepared. Slump tests, compressive strength, water absorption, permeability, durability of concrete against chloride ion penetration by electrical conduction method, surface resistance of concrete against chloride ion penetration and durability of concrete against freezing and thawing cycles were performed on the manufactured samples. The results showed that the addition of emulsion bitumen to structural concrete generally reduces the compressive strength and water absorption of concrete. Adding 6% bitumen reduces the permeability of concrete to the extent maximum. Regarding the durability of concrete against chloride ion penetration, the surface resistance of concrete against chloride ion penetration and the durability of concrete against freezing and thawing cycles do not have a positive effect, and in some cases, it causes a drop in these indices in concrete. Overall review, the results obtained from the conducted tests show that adding 4%, emulsion bitumen to concrete leads to better results.
