EXAMPLE ON ANALYSIS OF 3-SPAN CONTINUOUS BEAM BY MOMENT DISTRIBUTION METHOD(MDM) – SERIES(III)

“Feel The structure” MSA

Dear reader,

Here i have uploaded a solved example on moment distribution method. This is the third series on moment distribution.I request all readers to read series-(I) & series-(II) on same subject to clarify basic concept as i have started series-1 &2 with two span only. In this example, i have solved a 3-span continuous beam in which first span is uniformly loaded, second span is point loaded and third span is loaded with triangular loading. By going through this example, you will be able to solve 3-span continuous indeterminate beam effortlessly.

Download the complete solved example with detailed explanation on moment distribution from this below link.

Thanks & regards!

Download here an attached example solved for two span continuous beam by moment distribution method. In this example, a two span continuous beam in which one span is with uniformly distributed load and another span is loaded by a point load at center. In this example, far end is fixed.

In this example, i have tried to detailed out analysis of a continuous beam with moment distribution calculating BMD and SFD and i have cleared concept on carry over moment and balancing moment with giving some special notes.

Thanks & regards!

THINGS TO KEEP IN MIND FOR STRUCTURAL ANALYSIS & DESIGNING OF BUILDING

“Feel the structure” MSA

Hello! Structural Engineering Fraternity

       I am a Structural Engineer. My main work frame is to analyse & design simple to complex structure. I encourage many young civil engineers who have just passed out  from college and want to make a career in Structural Engineering.Also, my blogs will work as a tonic to some civil engineers who are already in this field but feeling very low due to lack of knowledge and skills. My blogs are certainly going to bring not only their professional growth but also they will start loving this challenging field.It will indulge them to be more innovative.

        I believe in 4’S&DE.

        S= Stability, S= Strength, S=Stiffness, S=Sustainability, D= Durability & E= Economy

         4’S&DE is my basic principle of analysing and designing any structure and same shall be followed by any Structural Engineers.I have seen many engineers who sometime think, if a structure is having sufficient strength against shear, moment and torsion instead of lacking in stiffness and durability, it looks fine to them. But i want to clarify one vital point, without having proper knowledge of deflection check(Based on Stiffness),Durability Check(Based on proper grade of material selection, life time exposure of structure to environment) and Economy (Based on client’s budget) no Structural Engineer is going to be very successful in their field.

         My friends, if you want to make a career as a RCC Designer, then it is very important for you to understand deeply about concrete technology. Until & unless ,you are able to understand the chemical reaction tacking place in concrete and adherence it’s hydration product to different deleterious gases and chemicals in the environment,you will not be able to judge which materials like  PPC or OPC or sulphate resisting cement is most suitable as far as durability is concern.You will be astonished by knowing the fact,sulphate reacts with the C-H-S gel(hydration product of cement) and concrete gets expanded by 300% by volume. You can feel now to what extent it can damage concrete by developing cracks and it further give path to ingress other deleterious chemicals like chloride to reach reinforcement. Also we should have knowledge about high performance concrete like high flow concrete & self compacting concrete where there is a congestion of reinforcement to avoid honey combing.

        And last one is economy. It requires rigorous analysis or you can say this is the most tedious part. In order to design building under the specified budget, we require lot of  reiteration process giving optimum member size fulfilling 4’SD.

         My main area of blog writing is to cover  4’SDE. Time to time, i will share excel sheets that will help not only freshers but also practising engineers.Also, i will regularly update you with some hand calculation for the analysis and designing of  simple frame and structural elements to bring you all to the basic. Please keep in mind, in fast pace of working environment, we are forgetting our basics and it is becoming very disastrous for all of us.Above all,i believe in sharing of knowledge and skills.What is the use if somebody is having huge knowledge and skills & carrying all these  to grave. I think,noting at all. I have realised this now and understood the importance of sharing. So, hope somebody will get benefit from my sharing. Also believe, even if a single person is able to uplift his/her career,then my blog writing will be successful.

       Most importantly, even a practising structural engineers will find something very new and innovative in my blog.

        Last but not the least, i will request you all who reads my blog to give their valuable observations/suggestions to improve it’s content.

Thanks & regards!

 Here you all Civil & Structural Engineers are invited to go through this basic example solved to clarify concepts on moment distribution methods.Everybody knows the importance of moment distribution method and how it is helpful to solve indeterminate continuous beams and frames.Here i am taking you some step ahead to analyse indeterminate beams and frame by creating interest on this vital subject.In near future,i am coming with several series on this topic having best examples to clear concepts.Going through all this series, you will prefer to analyse continuous beams and frame manually rather than with software like STAAD, ANSYS etc. As it is not a verbal / visual lecture, that’s why i have walked you through in details to foster this incredible subject. But keep in mind, when you will develop concept and principle of MDM by practicing examples, then i assure you, it will help you to solve simple frame and continuous beams in very faster and easier way. Please see the previous of the said example from below.

                                Sometimes it looks weird or you can say incredibly weird that how these examples are going to help as most of the concepts are available in books.But i would say to my readers that i have developed some tricky parts on this  which are very helpful to understand overall  concept of MDM without having visual lecture. Readers might be wandering here and there to foster concept of MDM by following some books but now i assure them all to go through this and upcoming series to develop tremendous subject of indeterminate frames & beams.I invite you all to be connected with up coming series.

                                  This is the first series on moment distribution with a simple example of two span continuous beam in which one end is hinged and other end is fixed.With this example, i have tried to explained to form table for moment distribution and once you are able to understand this table, then other associated part will be much easier for you. Also, i have solved in detail for the formation of BMD & SFD in non conventional method and it is quite easy to understand.
