So, for seismic if we are comparing rigid frame vs light concrete wall, is one better/more often used than the other? For instance, one of the disadvantages of the wall is it prohibits a lot or big openings unlike rigid frame.
And in terms of wind: what causes building to likely to overturn...
Thank you, Dauwerda for the explanation.
For a 3 story building, what is a vertical irregularity? Is it higher mass on level 2 (adjacent story) or on the roof compared to L1 (ground)?
It is my understanding that with earthquakes, lighter structure behaves better. And with hurricane and wind, heavier structure is preferred. Is this correct? If yes, does that mean rigid frame (lighter, flexible) perform better than concrete shear wall during earthquake? Thanks!
Got it. I should have thought about it before: distributed load is essentially the same as having multiple point loads acting on the beam. Thanks, guys!
Is there a quick way to determine which one has highest moment? Or perhaps we can extrapolate from say comparing the denominator (one point load: M=PL/4, but I don't know what are the formulas for 2 or 3 point loads)? Thanks!
