Appendix E provides an equation to calculation the "overturning moment due to seismic forces applied to the bottom of the shell" as the follows
M=ZI(C1WsXs+C1WrHt+C1W1X1+C2W2X2)
My question is when determining what the bearing under the ringwall should be, should the I in Mc/I be that of the...
I have a general question regarding safety factors. If you have sufficient test data for products/structural elements to failure, what value of safety factor would you recommend? I know some are dependant on the mfg., but if no recommendations are given, it is acceptable to us a factor of...
I have a situation where the anchor bolts for a sign structure were set too short and with the sign fully erected, the bolts are 2-3 threads short of the top nut. Is it possible to correct this without demo of the foundation and resetting anchor bolts and pouring another foundation.
I was looking for some reference or experience regarding beverage cooler slabs. I have seen some people have a construction joint and thickened slab for a cooler located within a building and others just have one continuous floor slab. It is always a slab on grade design.
I was asked take a look at some spalling of elevated concrete and corrosion of steel framing at an oil change location. What I found out is that it is precast planks and there are numerous locations where the prestress strands are exposed and rusted. 95% of this is near the bearing end of the...
Geotech is recommending extended footings to establish adequate bearing for a single story building. Anybody have some specs they recommend using. I think in the past we have used a 100 psi lean fill. Looking for a little advice.
Good morning everyone, I am looking for a seminar or class in the geotechnical field. Primarily dealing with interpretting soils reports and different methods for correcting poor soils. I feel as though I am simply as the mercy of our geotech engineer and would like some more background to...
Our geotech expert has taken another position and hard to get a hold of. He recommended that a geotech expert be in contact if the soil report shows standard penetration values less than 10 blows/ft. What should we be doing on these areas of the site to work around or correct this problem...
My brother has a 8" & 10" basement walls poured with #4 at 12" o.c. both horizontally and vertically. It is a rectangular basement, 28'x45'. The walls are 9' to joist bearing from basement slab. The 8" wall is the 45' wall and has developed a vertical crack @ 20' from the side wall on both...
