Load Combination- 97UBC

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Per 1612.2.2,  load factor for H ( soil pressure) is 1.6.  If I use equation
(12-5) should I reduce this factor.  To me this factor appears to be
excessive.  I understand that E includes load factor of 1.4.  

I think this load factor is excessive because if I were using 94 UBC for
strength design of concrete  the load factor for E would be 0.75*1.87=1.40.
And for H the factor would be 0.75*1.7=1.275

So the load factor for H  per 97 UBC is greater than LF for E.  Is there any
explanation for this ?

Thanks in advance.  Sid Lakhani
