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
