Thank's for your tutorial
Very Great work bro
from where can i get global materials
sir ,their is tutorial of laterally loaded pile???
بشمهندس ف خطوه الخوازيق البرنامج عندي مفهوش embedded pile بيظهر مكانه embedded beam مفيش حل للموضوع ده
مفيش اي مشاكل دا بس اختلاف versions اعملها Embeded Beams
This is very useful tutorial
Nice job, but below are some notes: - As the goal is to determine the ultimate capacity for this box or skirted footing, you are advised to use the associated flow rule in the soil model parameters. - Again, because you are after the ultimate capacity, it is better to capture the non-linear behavior of concrete by modeling it as elastoplastic material (with MC or Concrete model). - It is better to extend a rigid dummy interface beyond the footing boundaries to avoid stress concentration issues, singularity, and sharp edges effects. - Sensitivity analysis for the mesh might be done. - The way you apply the load to determine the capacity is only correct if the applied load at the site is also UDL. But if it is single or multi-point loads, this method is invalid because the BC is not a unique value for soil but depends on the load applied, among many other factors. - Make sure you add the interface surfaces. Ensure you don't double the concrete unit weight, as the replaced soil unit weight shall be subtracted! - Finally, FEM has a well-known limitation when it comes to large strain or deformation analysis (ULS), as in this case. Hence, if FEM is to be used, the Updated mesh option must be used in the calculation. FEM is a useful tool and will always give you results, but you need to be careful, calibrate it with different methods, and always compare it to a simple analysis method to see if the results make sense. All the best
You have richened my knowledge alot. I read all of those notes which I have studied well and totally agreed with you. But I don’t think that concrete non linear behaviour should be included as the major effect regarding the soil not concrete which could be considered as rigid and could be compatible with some of bearing capacity theories which assume the same methodology. And about extending the interface that’s a great idea. Special thanks for your time to write all of those for the learners here. Finally, I’m really looking forward to hearing from you to continue those decisions around. Would you mind dropping an email to: islam_ahmed@alexu.edu.eg please?
Thank you for the very useful video. Can i ask how i can obtain the tutorial define materials (i.e peat, clay, sand) ?
During excavation phase how do we have two soil volume
Great Video! Thanks. Do make one for pre-loading and PVDs application for ground improvement.
usefull. thanks
Hello, Can you help me in my project ...I am facing some problems regarding the failure load and bearing capacity.
what kind of problem
@@musaaslantas5460 I don't know how to get ultimate loads... My project is on GEO SYNTHETIC ENCASED STONE COLUMNS
@@PCEFaizanBashir I don't know the stone column application on plaxis exactly. But you can look at the literature. I would also recommend solving the problem analytically. you can use mstage ratio for ultimate load when doing analysis
@@musaaslantas5460 The loading is applied the same way as in other cases( sigma-z ). Since, i don't know much about Plaxis, that's why it is hard for me to analyse the failure load
Can I have your contact details?
How to apply load stage wise in different increment (say in 5 stages)?
You can increase load in increments in stages. Like in Stage-1 you apply a load of 50 kPa and in next Stage-2 add 100 kPa and so on.
السلام عليكم بشمهندس اسلام . ممكن اي طريقة تواصل مع حضرتك
Hello sir, thankyou for all. My thesis is depends on the effect of vertical drain with varied different diameter and spacing of vertical drain , but till now not clear about how to apply different diameter of ver. drain , the softwer is consider only spacing of ver. drain, so if you have any point about the diameter of ver. drain please help me.
You cannot apply the effect of diameter using that “line drain element” My thoughts about this is to model your drains as solid elements “cylinders” after that you click the volume and “decompose into surfaces” Finally choose your outer surface and assign a proper “Hydraulic Condition”
Can u share the extension again please🙏🏻🙏🏻🙏🏻
ممكن تليفون حضرتك

That's great video! I would like you to give me data on the layers of soil, sand,.... Mail: khangtranminh54@gmail.com Thanks you!
السلام عليكم شكرا اخي الكريم على الفيديو الرائع , اذا سمحت هل ممكن الاقي طريقة تصميم امبانكمينت لتربة محسنة باستخدام Dynamic compaction (Tamper wieght)? a;vh lr]lh
Thank you for the sincere effort. The material is good and clear.
How to apply bending moment at a point in plaxis 3D
In structure tab, You can find point press your mouse holding and choose "Point Load" pick your point and insert the load whatever it is. Or you can write the following command lines: _pointload 2 4 0 *change those numbers to your x y z* and change the values of your moments and normal. Regards
@@eslamahmed7022 Thank you 👍
Hi. I am facing a problem. I hope you will help me when analyzing embankments using soft soil model. The sttelment is higher than using soft soil creep. Is this correct and what is the solution?
eslam.ahmed18@engineer.com you can mail me anytime
Thank you
Amazing sir Please I request you to make for pavement with geogrid to analyse rut and fatigue.
Hello sir. Is it possible to change the properties of drains. As i want to analysis on sand drains under embankment ?
No it is not possible to do so as it is considered as uniform pore water pressure all the way through drain's depth. You only need to define the head (h) and the software will give pore pressure for all line drain node equal to defined head.
@@eslamahmed7022 can we divide soil into sand columns then keep sand as drained and clay as undrained. In that case is it possible ?
how can i load surface in plaxsi 3D
Create normal geometric surface Then press right click and choose add surface load after that you have to assign its value in properties window
Assalamualaikum gimana caranya mendapat program plaxis pak
you didnt give properties of sand to the sand drain.
You only need to define the head (h) and the software will give pore pressure for all line drain node equal to defined head. But you have to know that pore pressures that are less than drain's head will not be affected. In consolidation calculations drains usually reduce the excess pore water pressure to zero that's why I didn't put a specific head (h) because it will be ignored by the software, knowing that the properties that I'm talking about are under "NORMAL" behavior of drains. please refer to "3D-2-Reference.pdf" installed with software Page 156/540 Regards, Islam
@@eslamahmed7022 Thank you for replying. i want to do thesis on consolidation of embankment
Its very informative, Is it possible for analysis of Rock slope ?
Hello Aftab, I have already uploaded a tutorial for slope stability analysis. Nevertheless, rock slopes should be modelled with specific material model such as Hoek's and so on.
@@eslamahmed7022 Ok sir, Thanks, God Bless you
Is it possible to do analysis of nailed slope by plaxis 3D? If you know that can u please help me?
eslam.ahmed18@engineer.com you can send me an email to discuss about that
my friend its a wonderful tutorial... you are a genious 💜...
Thankyou sir it's clear tutorial for me but now i have some question: 1. How to define material of vertical drain? 2. How can i insert the diameter of verical drain? 3. How to apply triangular pattern for vertical drain?
You only need to define the head (h) and the software will give pore pressure for all line drain node equal to defined head. But you have to know that pore pressures that are less than drain's head will not be affected. In consolidation calculations drains usually reduce the excess pore water pressure to zero that's why I didn't put a specific head (h) because it will be ignored by the software, knowing that the properties that I'm talking about are under "NORMAL" behavior of drains. so you don't have to define its material nor diameter as we have nothing to do with stress analysis it is only consolidation analysis please refer to "3D-2-Reference.pdf" installed with software Page 156/540 About Triangular patterns, I think it is totally a geometric matter.

مع احترامي هل المحتوى الاجنبي بحاجة للمزيد ام المحتوى العربي ؟!، عداك عن اللغة الانجليزية الركيكة جدا التي تتحدث بها ولا اقصد الاهانة !
كنوع من المناقشة انا لا استعر من لغتي العربية لكن الانجليزية يفهمها العرب و الغرب و بالطبع اللغة ركيكة لانها ليست لغتي كل الفكرة اني عايز العربي و الغير عربي يتعلم لاني باختصار متعلمتش من العرب حاجه و اللي بيعلمك من العرب حاجه بيعلمك لهدف معين نوع من رد الجميل اني اسيب المحتوي بالانجليزية عشان يستفاد نفس الناس اللي علمتني و اللي مكنوش عرب
How can I model an cased excavation and secant pile in 3d ?
you can model it as plate element brother
Hey! Can you help in considering the effect of Soil Structure Intearction in Piled Raft Foundation using Plaxis
thank you very much , cheers
really thanks for this Tutorials, my model refused to calculate the second stage I have followed the same steps but still stuck in Excavation stage and it gives me an error that "Soil body seems to collapse" please can somebody help me? thanks
I think you haven’t activated wall elements (plate) in the stage which you have excavated
@@eslamahmed7022 no I have already activated both that why am wondering
