Hi! Why did you consider the member selfweight and at the same time you assign as distributed forces the beam and column weight? You are considering the concrete member selfweight twice? And must the floor slab be meshed to transmit the forces to all beams? You are attaching this slab just to the four corners of the building. Thanks
I also felt this . It got double load selfweight + member weight of column. Method of placing slab at four corner of building .It should have room to room plate.How it will be possible?
I have run the structure as presented. I have found that for panel 1 and 3 the slenderness indicated is more than admissible. Also the floor load on slab needs to be assigned as per the slab panels. Moreover, providing dead load of slab as well as beam in addition to self weight command doubles the load on the structure . Is it an undeclared lacuna in STAAD Pro that though self weight command is given we have to separately add self weight of beams, columns and slab as DL? I have seen this in other designs presented earlier. I am surprised to note that the seven story building does not have a lift and a staircase to move to storeys either. Provision of lift machine room and staircase headroom shall have their own effect for wind and seismic loads also. In many cases overhead water tanks are also constructed for potable as well as other uses which also need consideration in modelling as well as analysis and design. It is okay if the design is in initial stages for a single storey building. I think while presenting high rise buildings and following the code, load reduction shall also be applied with the rise in floor.
sir assigning self weight why u are assighned calculated bm & col wts ? and whole floor has taken as single plate is it correct? how the load will tansfer to the beams and columns can u give reply please.
Video was excellent.it would be better explained while assigning the loads without selecting the members how it assigned..and should be little slow while n designing..
Hye Mr. Shravan, my error shows thickness not provided for the surface. How to fix it? Secondly, why there is no load acting on the building when I applied wind load, is there any error in my steps? Hope to hear from you very soon.Thank you.
Self Weight is already assigned using -Y command. Why are you again adding self weight using udl both for columns and beams ? All elements are selected to design both column as well as beam. Assign beams and columns design separately.
Bro you are supposed to design different panel for each floor You can't just make a single shear wall for all the floors. It should be different for each floor
As per this case I was considered a single panel shear wall through out the building. If I design shear wall in each floor separately it will generate n number of panels for the building it is very difficult to design n number of shear walls in STAAD Pro software
@@civilengineeringbyshravan9596 thanks for reply..does this contribute major force values while analyse..can you make video regard design part- respective of the doubts.
@@civilengineeringbyshravan9596 Please make a video on shear wall analysis due to earthquake forces, also mentioned how to apply structural stiffness modifiers on beam, slab,column and shear wall as per ACI.
Brother, you are teaching wrong method. double self weight? why your shear wall design fail in staad output file? slab should be given as per yield line theory of IS456
What a waste .. once you have applied selfweight command then what is the need of calculating dead load and assigning them ? You didn't applied any lateral loads , what was the use of ur shear wall .. you given thickness of shear wall 120 mm , what a lame video
I made a major project on STAAD PRO in which we analysis the earthquake building your videos help us lot so mention you in refrence ❤❤🎉🎉
Sir Your videos are very good. Request you to explain little slowly.

The Output file in the video at 15:41 shows that Shear Wall Design failed. Please explain in detail why it failed and how to rectify it.
make shear wall into panels (decrease the height of shear wall) according to no of floors then you get the shear wall design results
Please make a video for calculating story stiffness for judgment of soft story.
YOU CREAT CONFUSION ,EVERY TIME
Please make one video on shear wall analysis and design by IS13920...with boundary element.

Why you are considering the beam load separately while the staad asign itself.
For understanding concept i was taken separately but for real time designs we will not consider
Already selfweight assigned ... Then why calculate the self weight and apply it again....
exactly the point Sir Muhammed! why Sir does he need to apply beam and column weights when he already applied selfweight?
Video was excellent.it would be better explained while assigning the loads without selecting the members how it assigned..and should be little slow while n designing..
Thank You for this ❤
Hye Mr. Shravan, my error shows thickness not provided for the surface. How to fix it?
Secondly, why there is no load acting on the building when I applied wind load, is there any error in my steps?
Hope to hear from you very soon.Thank you.
U can select the properties by missing attributes and missing property There we have error that u r not assigned thickness for that members

Very usefull.. thank u

G+20 buildings shear wall by using STAAD pro chupiva brother
WHAT ARE THE LOAD COMBINATIONS WE NEED IF WE DESIGN FOR WIND AND SEISMIC DESIGN???
1.2(DL+WL+EQ)
Load Combinations in STAAD Pro V8i Software ruclips.net/video/QLsLzyz2we4/видео.html
Follow this video
@@civilengineeringbyshravan9596 As per IS 875, wind and seismic load are not considered to act simultaneously. 1.2(DL+LL+WL) is okay

What will be the effects it is assigned as single panel throughout the height or single panel per floor.
The slab will take only the connections of corner columns only if we consider only single plate
@@civilengineeringbyshravan9596 thanks for reply..does this contribute major force values while analyse..can you make video regard design part- respective of the doubts.
Can you make the shear wall analysis for earthquake load with max compression and tension stresses evaluation.
Ya definitely 👍🏻
@@civilengineeringbyshravan9596 Please make a video on shear wall analysis due to earthquake forces, also mentioned how to apply structural stiffness modifiers on beam, slab,column and shear wall as per ACI.
Corner two of panel one is outside boundary of shear wall error what to do
modify the properties
How to model shear wall opening....
WANT IT TOO
Why not show reinforcement details in shear wall as well as like beam and columns design reinforcement details?
no need to assign column load as it take by software automatically
Can u make video of "Skip floor staggered shear wall structure" plz...it will be too much helpful for me...
In this video all the shear wall had been failed. how to pass all the sections?
Take correct values regarding grade and other vales
@@civilengineeringbyshravan9596 but you have given the correct values also its getting fail
@@MAR-vy9xm make shear wall into panels (decrease the height of shear wall) according to no of floors then you get the shear wall design results
BRO U DESIGN IT FOR DL AND LL ITS OK....BUT HOW CAN U DESIGN FOR WIND AND SEISMIC PARAMETERS???
Just we need to consider the combinations for the respective case
For wind and sesmic load as of same how you done for dead load and live load.
Where is surface self weight??????? assigning self weight in d.l does not include surface self weight
No load combination has been considered in the design.
your shear wall design has failed lets us know why what are the reason and how can we get the proper design
How to assign the shear wall self weight it self ?
Once if we assign self weight with -1 y direction factor it will directly assign the self weight for shear wall also 👍🏻
OKAY OKAY OKAY
WHY YOU ARE ASSIGNINGE BEAM, COLUMN LOAD SAPERETELY , AS SOFTWARE HAS AUTOMETICALY CALCULATED THEM.
Shear wall design failed your
Yes as per my assumption for thickness and load cases shear wall was failed assume anther thickness and try it once 👍🏻
