In this video, you can learn how to model a brick masonry wall in ETABS. What are the different steps involved in it?
To learn the basics of modeling in different software.

Please upload the vedio for analyse how to seismic analysis of interlocking blocks in infill walls using etabs
Very useful video Sir
Hello may is ask how would be the orientation of strut when theres a hole for window on the masonry walls?
Hello sir, Can we do pushover analysis for this masonry strut element in ETABS? If so, what type of hinges should we assign for masonry struts? Please let us know, it would be helpful.
Yes, you can do pushover analysis of masonry structure. I would suggest you to read some latest research papers on this work. The response of masonry is very difficult to model accurately.
A/s Obaid bhai, Please make detailed videos how to model brick masonry buildings (with openings) & its earthquake analysis.. either on etabs or sap whichever is easy
I will try to upload it as soon as possible.
@@CivilSAC Thanks a lot Ubaid bhai..it will help us alot
Hi brother your video was nice
I am here to know about how to give an user defined backbone curve for an X bracing strut (having hinge at middle of the X bracing) please help with this thank you
Dear Sir very good & informative video, can you share how we can apply walking induced vibration in Structure particular in load bearing structure, If Possible?
Hello Sir, pls provide step by step videos how to model brick masonry structures with openings in Etabs and it's earthquake analysis..i would be very thankful to you
There are many empirical formulas available in the literature. You can use any suitable formula.
Yes sir plz
in rc frames with infills, interface is very important aspect, how can we use the interface property?
For modeling the interface, your model should be very detailed. You should refer to some research paper in this area.
👍🏻👍🏻
kindly guide, how can we analyze for out of plane walls
There are many ways to model out of plane behavior. Please refer to research papers for this.
Thanks for the video sir, can u please clarify if we r converting the M wall to strut, do we have to add the load of masonary wall seperately in load define section.
Calculate the load of the masonry panel and subtract the load of the strut from it. Apply the remaining load on the beam.
@@CivilSAC thank you sir
@@CivilSAC A/S sir can u explain how to calculate the load of the strut?
@@tsewanggyalson8651 hey can u tell me how u calculated the load of strut ?
@@shaikhzoheb9025 What type of load are you talking about, please specify.
Sir What will happen if the Infill Wall has openings on it?
There are different methods to consider the opening in the infill. You can apply a modification factor for the size of opening. I will recommend you to refer some research papers on this topic to get the clear understanding of this.
I’m confused about the material part for the strut, why was the material not defined for strut as per the masonry data’s ? won’t the Material matter for stiffness or something?
Hello Sir. I want you ask you about the way to modelling the mansonry wall. How the way to modelling two, three, or more mansonry/struts?
you can refer to any research paper on this topic and understand how yo model multiple strut.
If the column in both side of beam is different (e.g. right side column is 15"x15" and left side column is 18"x18") then to calculate moment of inertia of column which column we select?
Please can you tell me why BM is there in strut as you assign as pinned joint
Do we need to assign strut as a compression element? if yes then how to assign it?
Yes, and for further information, you can refer to this video for assigning a compression-only element

Brother why don't have you put the modulus of elasticity of masonry infill in that section in etabs
this helps alot thankyou so much
Masha Allah Keep it up
What is the use of analysis of infall otherwise moment and shear force
Due to infill masonry the stiffness of the building increases which will affect the time period of the structure.
Please can you tell me how BM is there in strut as you assign as pinned it
due to dead load of the strut
Got this error: the structure is unstable or ill-conditioned etabs
why we don't take 2 diagoals ( x bracing )?
You can take X bracing also as there are many types of bracing configurations like X, V, Chevron, K, etc.
@@CivilSAC thank you, usually madonry infill walls work in compression ( axial forces), in a 3D building, we cannot predict the direction of earthquake, so it is better to take x brace. Am i right?
@@aymanramadan3235 Yes, you cannot predict the direction of the eartquake.
If you doing nonlinear time history analysis, then it is good to consider equivalent struct in an X configuration. For 3D analysis, you should also consider the out-of-plane bending of masonry infill panels which is a little bit difficult to model. I hope this helps.
If we draw masonry wall in etab it behaves like a shear wall due to continuity through out so how we brake at floor level.
You can use edit command to break the wall
First view bro
Oho..
24:24 why moments are coming in bracing although we have pinned them
Due to their self-weight.
When we have to consider both direction Eq forces.. then hw strut will be model.. is like cross bracing .. ?
You will have to prepare a 3D model to analyze for the earthquake in both directions.
Cross bracing will be helpful if you doing time history analysis.
