So if you have any query regarding the concerned matter, just drop a comment and we will try to solve it as soon as possible.
Can you please explain step to step design procedure for RCC and Structural Steel members like beam, column , slab and equipment foundations
To: Jitendra Arora
You may refer to “Reinforced Concrete Design” by W. H. Mosley. It is too long to write it here regarding the whole design procedures.
what is the ratio of mass and weight of concrete.
To: haresh,
The ratio of mass and weight of concrete is gravity.
I intend to install 5 off air conditioning units, weighing @140kg each on a reinforced concrete roof. I dont know the specification of the concrete, but there is other plant on the roof such as air handling units, package chiller, boiler house etc. So i guess it has been designed as a plant room, load bearing roof.
The landlords agent wants an endorsement to say that what I intend to do is safe. I have contacted a structural engineer who has told me that without any construction drawings or specification of the roof, there is no way he will endorse my course of action.
What can I do now?
To Jeremy Giddings:
The Structural Engineer has to obtain design information such as the thickness and reinforcement details of the roof to check if it is structurally adequate to support your proposed loads.
Just give him the design drawings of the roof.
SIR,
I PURSUING FINAL YEAR,CIVIL ENGINEERING.I WOULD LIKE TO KNOW ABOUT THE INNOVATIVE MATERIALS IN CONSTRUCTION
To Reddy,
There are many innovative materials developed in the construction industry. For example, fibre reinforced plastic is proposed to replace traditional steel bars as concrete reinforcement.
I have tried the procedure for Sheet Piling near a rail line, where I have to include a relatively large surcharge. I’m then having trouble with the procedure in that on step No. 5, I’m coming out with a negative value for p6. This then yields a negative dimension “D” on Step No. 6.
Your program is helpful, but could you respond a.s.a.p. Thank you for the help.
Bob Dodge, S.E., P.E.
Bob, I am designing some shoring and ran into the exact same problem you described. Did you ever get this resolved? Thanks.
Sir,
What is the salary for civil engineers inside & outside, i heard that civil engineers have a great opportunity in gulf countries is it true
Sir Im taking up my undergraduate thesis this semester i would like to ask if you have any suggestion for a thesis title for me focusing in the field of structural & hydrology / water resources engineering etc. cause some of the group have took transportation and materials.
Thanks. hoping for your suggestion.
what thesis can we do for 2months time frame
Hai sir, Can you explain the economics of civil engineering and try to send that data to my mail.
my project is geometric design of a railway track plz send me best material about this project and also how to design a raily curve
sir,,kindly tell me the format of making a summer training report
To: Ananya
The summer training report can be presented as follows:
(i) Introduction
(ii) Programme of training
(iii) Skills and kowledge leant in training
(iv) Evaluation
(v) Discussion and Sharing
(vi) Conclusion
okay..thank you sir
sir,if the drawing of a beam is given then how to find out the steel ,,,i mean the area of reinforcement
sir vincent t.h.u thakyou for ur support
im in 4th year civil engg,,and my interest is in construction site work,,tell me sir,,what should i study after my b.tech
What are the disadvantages or problems faced when using the total station equipment
We want to construct A concrete wall at the sea shore. The soil investigation shows filled up soil upto a depth of 4m and further down is lateritic boulders and laterite rock. Now vertically at a distance of 12m from the proposed concrete wall the soil investigation shows marine clay with fine sand. I want to know whether is it safe to go bored RCC piles so as avoid sliding of the structure.
To Rajendra
To avoid sliding and deep-seated failure, your proposal to construct bored piles as foundation of the concrete wall is a feasible option. Depending on the scale of your wall, you may consider mini-piles ore pre-bored H piles which may save your costs.
I suppose the bored piles are designed as end-bearing piles which are founded beyond 12m from ground level. If it is intended as friction piles, careful analysis has to be carried out.
sir,why do we carryover half of the moment towards a hinged end also as in the case of fixed end in moment distribution method
To merun,
Consider a singled-span beam with one end fixed and one end pinned.
MA, required to cause a rotation at the pinned end, x, may be expressed as follows:
MA = 4EIx/L
When this is true we find that moment induced at the fixed end
MB = 2EIx/L
Hence we may say that a moment of magnitude 0.5 of moment A from pinned end is
’carried over’ to the fixed end of the beam when MA is applied at the right. Hence the carry
over factor, CO, equals 0.5 for the structure.
In moment distribution method, the first step is to establish a false structure by fixing all joints. The fixed fixed beam structure is not the real situation, so we release each joint one
at a time and put in a moment to cancel the sum of the fictitious moments at a joint
and when we do so, we distribute the cancellation moments in accordance with the
distribution factors. While one joint is released the others are fixed still. While one joint is fixed and the other released, 0.5 of the cancellation moment goes to
the opposite side of the beam span. Hence, we carry over half of the moment towards a hinged end also as in the case of fixed end in moment distribution method.
HI,
Dear Sir i hope you will fine.Sir i need to you about the steel elongation and how it can be calculate and what is the affect on steel durability.
I will be very thankful to you
To Mohammad Tasawar Riaz,
Just from elastic theory,
Elongation = Stress x length/Young’s Modulus
We have limitation of allowable elongation, otherwise the performance of the structure would be impaired.
I would like to know, how we can co-relate the compressive strength of the concrete after conducting an ultrasonic test?
How reliable is ultrasonic test?
To K.P. Gopinathan
The relationship between ultrasonic pulse velocity and strength is affected by a number of factors including age, curing conditions,moisture condition, mix proportions, type of aggregate and type of cement. If an estimate of strength is required it is necessary to establish a correlation between strength and velocity for the particular type of concrete under investigation. This correlation has to be established experimentally by testing a sufficient number of specimens to cover the range of strengths expected and to provide statistical reliability.
