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...

A Collection of Some Quotes

Quotes may have a good influence in life. Some quotes make us more positive about life when some help to see life from different perspective. They also have the power to revitalize our lives. I would like to include something from the movie  “Three Idiots”  – Rancho:  That day I understood that this heart scares easily. You have to trick it, however big the problem is, tell your heart, 'Pal, all is well. All is well.' Raju:  Does that solve the problem? Rancho:  No, but you gain courage to face it. So, going through positive or inspirational quotes cannot solve anything but these will give us strength to face everything. These quotes are collected from different books, movies, facebook pages, famous people etc. Here are some of them: 1.        Shift your focus from source of pain to what is desired 2.        All our problems have a solution and problems are not stop signs, th...
