Temperature load not included in automatically generated combinations ASCE-7 ASD

[mohamed.agrody]

I have applied +30/-30 celsius load on all members and panels but it is not included in any generated combination

they should be included as per equation 16-9 IBC

D+L+T

model attached

Hi @mohamed.agrody.

This is happening due to lack of coeficients in ".rgl" default for ASD ASCE 7-10.

I´m not familiar with ASCE but maybe it´s a issue to fix.

Best regards,

Caio

Thanks Caio for the tip I'll try editing it

@CaioSaporito 

i Edited it as in the picture

but it didn't achieve the result I wanted

I wanted equations

2 D+L+T

4 D + 0.75 (L+T) + 0.75 (Lr or S)

only equation 4 was generated but not 2

while the rgl file has

ULS:2. D+L:2 + 32 + 0 + 0

ULS:4. D+0.75L+0.75S/Lr/R:2 + 36 + 0 + 0

rgl file attached

can you help with that?

Hi @mohamed.agrody 

In your modified rgl file, you used formulas:

| 32. LIVE(1,n)*gu(i)*Psi0,1(i)

| 36. LIVE(1,n)*gu(i)*Psi0,2(i) + SNOW(1,n)*gu(i)*Psi0,2(i)

where LIVE load type refers strictly to Live loads, not including Temperature cases.

You can use instead

| 16. Q(1,n)*Psi1(i)

| 26. Q(1,n)*Psi0,n(Q)

where Q include all Live, Wind, Snow and Temp loads case types.

Try attached rgl file.
