Thank you for this amazing video with all the concept. I have a question, At 26:54 when it is load case 1 and wind direction is W to E. According ASCE 0 to h and h/2 .. all these region are horizontal distances from windward edge. When windward edge is at west then how these pressures can be illustrated in N-S directions???
And at 31:30 when windward side is the South Side. Is it right to apply pressure according to Section A-A ? Because in section A-A the concept of 0 to h is no more applicable because it is not a windward side.
Thanks for liking. For h/L less than or equal to 0.5. We have to take 4 regions from 0 to h values are -0.9 and -0.18 and from h to 2h and 'greater than 2h, they are tabulated similarly. No need to take average. They are 2 values means we have to take two cases ... Case 1 and case 2... See at 22:40
Great video and explanation sir.. but i have a clarification.. Example: 1. As per the table.. for both parallel or perpendicular to the ridge.. the wind will be upwards or suction? 2. Then the horizontal dist from windward edge will be both applicable to either parallel or perpendicular to ridge?
Thanks for Appreciation. 1) See first video titled Wind Loads Calculations using ASCE 7-16 - Part 1: Basic Mechanism of Wind Load on Structures. you will find the answer 2) See the table in FIGURE 27.3-1 ASCE 7-16, in both the cases (Normal to Ridge for θ < 10° and Parallel to Ridge for All θ) Horizontal Distance from Windward Edge need to be used.
If we are talking about the wind load on the structure of solar panels then the formula for calculating wind load will be taken from open buildings with monoslope roofs ?
Thanks for appreciation... qh is calculated by same formula as qz but here z = h (mean roof height).... For determining flexible or rigid structure, there are seperate equations (see in ASCE 7 )used for calculation value of gust factor G but in these videos i have just considered a value of 0.85 as it is normally we get for rigid structures...
Hii im fresher structural engineer i had one doubt here what is meant by case 1 and case 2.I thought that case 1means windward direction and case2 means leeward direction is it correct,can you pls clarify this one
Hello Dear. There are two cases. because of two values of Cp given in Table of ASCE 7-16 Figure 27.3-1 Roof Pressure Coefficient. Upper portion table windward section. there are two values and lower portion table -0.9 & -0.18 similarly other values listed in the tables
During ''Design Wind Pressure'' you ignored the MWFRS formula nagative sign, just carry out positive and negative sign why ? and that effect the positive CGpi and Negative CGpi
Best video on TH-cam on the subject!
Thanks for Sharing. Keep Sharing !
amazing video this video should be viral and everyone should take the benefit through this video. waiting for the next problem video
No doubt.. This guy have explained each and every point with details. Excellent work

Incredible work mate, i'm an Optometrist and I can follow this. You must make it easy for the engineers.
Thanks for Sharing. Keep Sharing !
Best video on the subject. Very helpful. Thankyou😊
Thanks for Appreciation. Keep watching and sharing
Job well done! What a legend you are
Thanks
Good stuff! Really helpful to understand and prepare for my PE exams. Thank you for the video!
Thanks for Appreciation ❤
Thansk for amazing video....i have a little question about roof wind ln case multi storey structure. Should we apply for each storey roof separately ?
Thank you for this amazing video with all the concept.

Thank you brother for appreciation... In example 2 (next video) i have discussed this mistake and rectified this.. Please see that video..
Thank you so much. You saved my life!
How ? Please tell me 🙂
And at 31:30 when windward side is the South Side. Is it right to apply pressure according to Section A-A ? Because in section A-A the concept of 0 to h is no more applicable because it is not a windward side.
Very helpful video. Thank you so much.
You're very welcome!
Thank you! May I ask a question: at the video time about 19:50, when you use the Cp is -0.9/-0.18, is the value is peak value or mean value?
Thanks for liking. For h/L less than or equal to 0.5. We have to take 4 regions from 0 to h values are -0.9 and -0.18 and from h to 2h and 'greater than 2h, they are tabulated similarly. No need to take average. They are 2 values means we have to take two cases ... Case 1 and case 2... See at 22:40
Good explanation
Is there any video regarding Envelope procedure
Thanks for the Appreciation.. In Sha Allah soon
Great video! Thank you so much!!

Well Explained.

Yes, Wind Loads for Solar Panels structure are to be calculated from open building provisions of ASCE 7
Thanks again It was really amazing videos , do you excel separate sheet for the wind load calculations
Thank you for Appreciation... I didnot use excel sheet here.. I just explain how wind load is calculated manual hand calculations...
very useful, thanks
Glad to hear that!
nice
Thank you so really appreciated
Thanks for Appreciation. Keep Sharing the videos.
Hi how to calculate qh and solve a problem for flexible structure aswel.
Thanks

Can any one explain when h/l value is in between 0.5 and 1 then how to calculate cp value of roof

Hello. is it possible to have the PDF ? Thank you
Yes.. Plz share email address

I have highlighted and rectified this mistake in problem 2 video. please check
when Gcpi is + then it should be -.6 and when _ Gcpi Then it should be +
Yes Thanks to notify. I have rectified this in next video. You can check
@@analysisdesignstudio3363 Thanks . Can you please make a video how this loads act as point load and line load and how these can be used as modeling
@@arpitabose9706 Yes In Sha Allah I will make tutorials about this.
