Presumably this is not in the USA. Still, 80m is a long way to fall ! Make sure someone else has climbed this before, as take your fall restraints with you !
Keep in mind also if substantial lengths of rebar are on the surface, the load-carrying capacity may also be compromized. Skin repairs are generally expensive, and best done at the factory. Send the culverts back, dont take liability, as even with the best repairs, they are liable to corrode...
I've never felt adequate, yet for the last 25 years, I've worked all over the world, and they still hire me ! You know you'll shine on some days and some projects, and on some you wont. Just be humble enough to know you can learn from everyone you meet, and if you do the right thing every...
Does anyone have experience of using expamet as a construction joint former for thick pours ? I have a 5 ft thick slab (20ft x 88 ft). The contractor wants to break up the pour using expamet rather than regular formwork, presumably so he can get his shear dowels through easily. I always...
I'm as confused as Ron. Your pile is short & stiff. For whatever reason you need the point of fixity (do you mean center of rotation ?) try the brinch-hanssen method - works well for short piles.
Totally concur with TDAA, and would add that required (or desired) parameters would depend on type of pile chosen, whether lateral loads present. e.g. if deflection is an issue, lateral soil modulus would be helpful. You dont always get everything you ask for, so ask for a little more.
You're getting there if you were amazed how your first calculator took mere seconds to calculate 2+2. (The batteries drained soon after that !)
Did anyone record their first programs on audio cassettes ?
Knowing that the footings cannot "actually" overturn if they are moment-connected to the columns of a rigid structure without breaking that connection, it is probably valid to 'push' the theory, and use soil frustrum counterweights or whatever helps to avoid unnecessary overdesign. As for...
Scenario 1 : The floor is independant of the walls ; In this case you can just rip the old floor out, dig down another 18 inches (upto top of wall footing), and cast a new floor.
Scenario 2 : The floor is either integral with or acts as a strut for the base of the walls ; in this case, you may...
If the grade beams have closed ties, they would project through the cold joint into the slab, hence shear transfer is effected. Also the two are tied together, mitigating what Ron said about expansive clays possibly lifting the slab off the beams. My concern would be durability, since we now...
what you are doing is excellent, i.e. direct the problem away from the concrete. At a recent refinery project, we used an epoxy paint to "surface improve" the concrete (after smoothing out the surface) - this stuff is wonderful at isolating the concrete from the sulphate attack. Surface...
SlideRuleEra is correct in his/her previous comments, however my experience with residential slabs, because they are generally covered with carpet, differential settlement will show up more readily (and be more difficult to fix) than any local damage due to load transfer between new & old. If...
