Check out Foundation Engineering Handbook by Joseph Bowles (excellent book). He has some formulas for checking overturning when you are outside the kern point
Any California engineers out there? I was wondering if someone could describe to me the process a structural engineer goes through to obtain a building permit in California. It is my understanding that the Authority having Jurisdiction will complete an independant technical review of the...
You are correct, the columns are 40 ft tall. Thru each of the 2nd, 3rd and 4th floors, they will be laterally braced by the floor sheathing. However, it is not my intention to attach any of the lower floor levels to the steel columns in any fashion. Therefore I expect the problem will only be...
We would normally do a masonry corbel.. i.e. and 8" block, then 10", then 12" (all grouted solid) and then bolt a 2x4 nailer to the top of the 12" block. For the second floor continue your 8" block on top of the 12" corbel. You will want to use a top chord bearing...
Are you suggesting engineered wood products for all of my stud wall assemblies? The source of the shrinkage is on the top and bottom plates of the stud walls....
I am working on a 4 storey multifamily wood frame building and have to put some steel columns from transfer slab elevation up to the roof to pick up some heavily loaded steel roof beams (Pf ~ 250 kips). The project is on a ski hill with roof snow load of 300 psf. The problem we have is that the...
Could you elimite the lateral issues on your piles with some batter piles? This may bring you a little more closer to a "rigid" foundation system (i.e. high natural frequency) where you may eliminate or greatly reduce any amplification effects from you pile system.
