thank you sir
Ngayon malinaw na, na ang mga computer ay hindi direct na nakakaintindi ng mga numbers tulad ng 1, 2, 3. Need muna nitong gawing 0 at 1 ang mga ito gamit ang binary system. After maging binary, ginagamit ng computer ang mga logic gate para ih process ang info at makuha ang tamang results. Wow!
It’s amazing how excel can be use to explain how computers read and process numbers ❤, good job sir James🎉
i've learned so much from this discussion thank you!
the condition number 3 say that the building is near the crest or in the up half hill, which is not in this example !
Would it be possible to purchase the spreadsheet from you?
Thank you for the materi sir. I want to ask what is the value of "e" in the K3 formula ?
e is constant and is called "Euler's number" the base of natural log function. It is equal to e = 2.71828
hello sir, pwde po ma shareniyo po copy of your NSCP 2015
pahelp po everytime nag si-sign up ako lagi lumalabas yung "We're sorry, but something went wrong. We've been notified about this issue and we'll take a look at it shortly."
Thank You Mr. Olivo
Very good and i would like to have Excel spreadsheet for gust affect factor for flexible structure Would you pl send me
The chicken!
Hi po. If mas malaki po yung shear from rsa, need pa po ba iscale down to equal it sa static shear or no need to scale na po and as is yung shear from rsa na gagamitin na? Ty po
Ung sa RSA na base shear na po gamitin niyo.
@@ryanjamesolivo6516 okay po. normal lang din po ba umabot ng more than 2-3times ang laki ng rsa compared sa static?
what is the classification of streetlights or lamp posts in calculating wind loads?
can u please send me excel?
Dear Sir, Thank you very much for the valuable video. Would it be possible for us to have the Newmark excel sheet Thanks
what are the formulas for k* , a1, a2 and a3 ?
Sir lecture video po ba ito ng masters or undergrad?
para po sa undergrad po i2.
Good day, sir. If possible sir, pwede po maka hingi ng excel file niyo for topographic effects sa wind load? Salamat po sir!
for K1, is it K1*H/Lh or K1/(H/Lh)? as per your video you multiplied 0.85 to H/Lh instead of division.
yes po, you multiply, kasi K1/(H/Lh) = 0.85. So K1 = 0.85*(H/Lh)
hi, can you leave me a contact. I need help for calculating wind load for mounted solar project.
Sir, if the problem states that we assume a 2d-hill, do I use the 3d-axisymmetrical hill or the 2d ridges?
just assume 2d ridges.
thanks
Sir question po. Pano po kapag angle < 10 deg.. then ang wind is normal to ridge.. both for wind ward and lee ward side ba eh same ang Cp? Sample.. h/L = 0.5, Cp will be both 0.9 . Then other case is both 0.18?
Gamitin niyo po ung table po ng parallel to the ridge, ung may "Horizontal distance from windward edge"
Ano po ang time history analysis?
paghanap po ng response ng isang structure sa actual or synthetic earthquake (ground acceleration vs time graph). Numerical analysis po it ng differential equation. You can watch my video about an example sa Time History of a single degree of freedom system ruclips.net/video/VEyEpXFN6sA/видео.html
Hi Ryan, can you share the excel sheet
Good day Sir. Engr.! May I know what book are you using in this video? Seems clearer than the NSCP 2015 pdf that I got from the internet. Hehe
ASCE 7
Membrane will not contribute to frame stiffness. But what will be the difference when we will not change the modifier to 0? Thank you
Yes, membrane does not have an in-plane stiffness, but it has an out-of-plane stiffness. Therefore, if you want to remove the out-of-plane stiffness modify the stiffness properties of the membrane to 0.
@@ryanjamesolivo6516 thanks. Sir i try another way. Instead of stiffness modifier i used material property with 0 weight. The shear and moment almost the same. But for the axial big difference. Any comment?
That is a great explanation. I like it, sir. But I have one question. can we choose any mass and stiffness value to get maximum responses, or are there any recommended natural periods that we can use to collect maximum responses of the system for each damping ratio? with regards!
Yes, we can graph all the different periods of vibration vs the maximum responses (e.g. acceleration, velocity and displacements) this is what we call the response spectrum curves (RSC) We use RSC for response spectrum analysis (RSA). Most earthquake codes uses a damping ratio of about 5% Responses are a function of the period/frequency and the damping ratio in RSC.
sir what if yung h/L is 0.46 consider 0.5 na po ba?
Kung normal to the ridge, interpolate niyo Po, kung parallel to the ridge consider niyo 0.5,
@@ryanjamesolivo6516 eto po siya sir di ko po kasi alam paano na derive sa -0.81 and -0.17 sa windward yung sa reference ko Roof Pressure Coeff: h/L=9.75/21=0.46 Winward -0.81 -0.17 Leeward -0.49 Roof Angle=13.39 deg. interpolate muna po ba yung value ng h/L before yung sa angle? 0.25 -0.7 0.46 x 0.5 -0.9
Helpful yung mga videos mo sir. Especially yung Response spectrum analysis na discussion mo using the software. Nagkakaidea na kami as students about seismic design. Thank you sa effort ng pagdiscuss I hope na marami pa kayong maturuan.
Can I have your excel file sir? About the elcentro earthquake using newmarks method?
Sir thank you sa vids! Very helpful. More uploads to come particularly earthquake engineering haha nscp 2015 godbless po
