RC Beam Analysis With ANSYS Step by Step

Image
ANSYS Multiphysics 11 is used here for the analysis of Reinforced Concrete Beam. In ANSYS, all the units should be converted to a same unit and just use the value. For modeling concrete structure in ANSYS, Solid65 element type is used. This solid is capable of cracking in tension and crushing in compression [1]. In this tutorial, the use of value -1 for uniaxial crushing stress removes crushing capability and cracking of the concrete control the failure of the finite element model [2]. The shear transfer coefficient describes the ability of an open or closed crack to transfer loads. These coefficients can vary from 0 to 1, with 0 indicating a very smooth crack and 1 indicating a rough crack surface [3]. Here, open shear transfer coefficient is considered as 0.3 and closed shear transfer coefficient is 1. Uniaxial cracking stress is 3.6e6 Pa .  Elastic modulus and Poisson’s ratio for concrete and steel used here are respectively 3e10 Pa, 2e11 Pa and 0.2, 0.3. Beam dimension: Len...

Algorithm, Heuristic and Metaheuristic

The three terms – Algorithm, Heuristic and Metaheuristic – are often used in Engineering fields. Knowing about these terms could be beneficial.   Algorithms  can be considered as any sequence of operations. Computer programs contain algorithms which have detail instructions so that specific tasks can be performed by computer. Flowcharts and programming languages are most commonly used to express Algorithms. In optimization problems, heuristic algorithms can be used to find a solution. These algorithms work by getting closer and closer to the optimal solution in a relatively short time as they progress. Tabu search (deterministic algorithm), simulated annealing algorithms (non-deterministic algorithm), genetic algorithms are some of them.    Heuristics  can be termed as strategy derived from previous experiences with similar problems. Many heuristics algorithms are specific and problem dependent. Metaheuristics  may be used fo...

How to Make 'Payesh' in an Easy Way

The dessert 'Payesh' is delicious to eat. I like it so much. Here is an easy recipe to make it. Ingredients: 1 liter milk   Powdered milk   Polao rice   Sugar Recipe: Heat 1 liter of milk over mild heat for about 40 minutes. (Pay attention whether the milk overflows. Stir to break up the foam as it forms). Mix a cup of water with 2 spoons of powdered milk and pour it into the liquid milk which is still heating and let the mixture be heated for another 20 minutes. (By this time – it can be said after total 50 minutes – wash 2 handful ‘Polao rice’ and soak it in enough water for about 10 minutes). After 20 minutes (it has been now 60 minutes total), drain the rice and add it to the milk. Keep stirring to avoid sticking of rice. Let it be cooked for about 20 minutes now. Add sugar as per your taste, stir and cook for another 10 minutes so that the milk thickens. All these take total 90 minutes and now turn off the flame. Let this be cooled and the m...
