Crowd loading

Question:

Hi,

May I have some support in applying the crowd load, please?

I’ve watched a few videos and it’s said that the load is applied in the same way as walking load, however the equation in EC gives results in kN/m2 and the function in Midas is completely different to the equation in EC1-2, NA.2.44.5 and it also includes some constant parameters, which MidasUser help doesn’t specify how to obtain.



Could someone please assist me?


Answer:
Thanks for writing to us.

We can compare both equations of code and sinusoidal midas equation as shown in below snapshot:


I understand this can be tricky, just that we need to be careful with units. Furthermore, I created an excel sheet where i have done manual calculation. PFA.

Parameters are also explained in help manual. http://manual.midasuser.com/EN_Common/Civil/865/Start/05_Load/06_Time_History_Analysis_Data/Time_Forcing_Functions.htm


Hope this helps, kindly reply back if you have any further issues.
