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!

Thank you for the materi sir. I want to ask what is the value of "e" in the K3 formula ?
@ryanjamesolivo6516 5 ай бұрын
e is constant and is called "Euler's number" the base of natural log function. It is equal to e = 2.71828

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.
@ryanjamesolivo6516 Жыл бұрын
yes po, you multiply, kasi K1/(H/Lh) = 0.85. So K1 = 0.85*(H/Lh)

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?

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 kzbin.info/www/bejne/jHbcdqOOe7NpqaM

Membrane will not contribute to frame stiffness. But what will be the difference when we will not change the modifier to 0? Thank you
@ryanjamesolivo6516 Жыл бұрын
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?
@hussienalkasim1672 Жыл бұрын
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!
@ryanjamesolivo6516 Жыл бұрын
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.
