Signal Timing for the Intersection
Просмотров 1362 месяца назад
The data is given for peak hour volumes for a four-leg intersection on a highway. Using the Webster method, determine a suitable signal timing for the intersection using the four-phase system shown in the following table. Use a yellow change red change interval of 3 sec and the saturation flows given .
Length of Queue Due to a Speed Reduction
Просмотров 973 месяца назад
One sunny day The volume (flow q) at a section of a two-lane highway is 1500 veh/h in each direction and the density is about 25 veh/mi. A large dump truck loaded with rocks from an adjacent construction site joins the traffic stream and travels at a speed of 10 mi/h for a length of 2.5 miles along the upgrade before turning off onto a dump site. Due to the relatively high flow in the opposite ...

Nice detail video ,please continue.
Awesome video thank you :)
Great professional professor. I learned alot . Shukran
FREE CLASS, WAY THE BEST CLASS
Thank you so much, I learned way more then what I have learned last 6 years in civil 3d design
Good looking pub in the tractor.
The date conversion (at 07:23) isn't working for me. Formatting the cell to "General" doesn't convert my date to a number (43710 and 43774 in your example at 08:11). What am I doing wrong?
this tutorial is really great for beginners , thank you so much
Thank you for this video Sir. Please do you have a video where you model the joints and do a load simulation of a bridges?
II learned more about Civil3D in this 23 1/2 minutes than I have in 30+ years of Heavy civil surveying. Thank you so much and I wish I had seen this 4 years ago
Thank you so help full 🎉
Very helpful sir. your channel will grow...
Thank you for sharing. How do I calculate lateral pressure for SCC?
The lateral pressure of self-compacting concrete (SCC) it depends on the amount of pressure it exerts laterally when fresh. The design of formwork is governed by this pressure. For slump greater than 2.5 inch p= (3.28+0.26Rt)Wc>=630<=Phydrostatic
@@nasseryariphdpe648 thank you for the reply. I’m preparing to build forms for an 8’H x 40’L x 10”W garden / privacy wall. Before I do, however, I need to figure out how much scc lateral pressure is / will be. Perhaps I need to just consult a structural engineer. Thanks again! Be well
How to add diaphragm in infrawoks
Maximum Bending moments = wL²/8 Bending stress = Mc/I. Please don't confuse the twp
Bending moment and bending stress are two different. Bending stress is the internal resistance a component develops when an external bending moment or force is applied. This bending moment causes the component to curve, which in turn creates tensile and compressive stresses within the structure. These combined stresses are known as bending stresses. Max moment for simply supported beam is wl^2/8.
sir, you did not include M_wearing in your M_DL.
4:10 Sir, I think you did I_z - (sum of A)(y')^2 instead of plus.
HOW TWO DIFFERENT DIA OF TUBE TIE BY COUPLER ? , DON'T YOU THINK DIA SHOULD BE SAME FOR POST AND BEARER
INSTEAD OF ELASTIC SECTION MODULUS , SHOULD WE USE PLASTIC SECTION MODULUS M=Fy X Z
SIR, YOU TAKE BEARER BEAM AS SIMPLY SUPPORTED IF BOARD BEARERE IS USED, THEN THE POINT LOAD WILL ACT AT THE RUNNER, SO WHAT WILL BE THE SUPPORT CONDITION OF RUNNER , IS IT SIMPLY SUPPORTED OR CONTINUOUS BEAM
Thank you, Professor! Very helpful
Thank you very much. Needed this for work.
thank you for helping me, but can plz show how to make reports for cut and fill and section views, thank you for waiting your feedback.
I have link for cut and fill and more please read the description and links below the title.
@@nasseryariphdpe648 , Could you send me link for them?
Thank you very much sir, Allah bless you. learnt a lot from this lesson.
Goated tutorial
Here in new mexico, they bank all corners the opposite way, keeps the drunks halfway off the road at all times, reduces safe speeds when its raining, a crowned road is a rare phenomenon, blinkers are optional for drivers, guardrails on flat roads and nothing on mountainous winding roads, potholes take 5 years reporting before attended, better stick to horse and wagon to avoid the lean toward the outside.😂
Hello Dr. Yari, just want to make sure I understand correct about the moment. For M windlow, 5+15 is superstructure + high water and 10+5+3 is 1/2(5+15)+low water height and low ground height? Thank you.
Explains several key components of grading. I learnt a lot. However, after 30 minutes, the surface creation could have been done better. The interior surface spilled outside the parking area. This should have been corrected. After correcting this, go for outside daylight grading, create the daylight surface in one shot. Paste them together. This would have avoided lot of confusion.
For the As in step 10, does it always add 1.1" of the width and length of ice load? And does 1.1" come from ASCE somewhere? Thank you.
No, its based on location it can vary from 0.25 to 1.25.
i thought at first he got lost in cosmos
You Rock, you are a great teacher🤘
Thank you
Omg at last i found this vid thank u very much sir u really helping me..struggling to underatd the beginner method for create road surface tq tq tq
How do I decide to use either ACI 347 or ASCE 37-14?
Lateral Pressure on formwork is addressed in both ASCE 37-02 and ACI 347-04, but there are few differences in both: - Column Forms ASCE states maximum limit of 3000 psf, however ACI has no upper limit. -Wall Forms ASCE doesn't consider the placement height, but ACI use 14' as one of the applied conditions. ASCE uses 2000 psf as maximum pressure but ACI again has no upper limit. They both are accepted . I would use ACI.
Thank you !
Thank you sir❤
So confused… how does this video set up work? Are you writing backward? Love it
No, the software convert to horizontal flip.
How do I start with the table. Do I create it elsewhere then insert?
Hi can you do in in a three moment equation? Thank you
Why dont we calculate member FC or DC?
❤

Great video.. described with utmost clarity~!!
Great video, You writing backwards is 200x better than my handwriting forward. Thanks for the video.
Thank you so much! Your explanation is very clear and straight forward! God bless you!
Hi Nasser, one question I have is when you sloped the exterior of your building 10' offset at 2%. How did that work? Since we are projecting to proposed surface that is already sloping 2% in the opposite direction so if we are forcing it to slope at 2% we might not get 10' equally around the building to tie-in to existing surface? Meaning the tie-in point would be lower than the proposed surface so that would not work? Can you please explain. P.S.: I am a Microstation guy trying to learn Civil3D. Thank you! Toufic Awad, P.E.
Very good question. He should have gotten the surface elevation of the outer line, and offset the outer line 10' and +2% to inner line. None of the dummies caught it.
@@pchander100 well, thanks man! tbh i don't care anymore lol I ended up spending the money to buy OpenRoads designer and do the civil work there since I am more familiar with Bentley products.
mine wasnt showing any roller support, does it came in default? or I must create one myself?
You need to creat one just like the example in the video
damn!! this is so satisfying
