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...
It is a walk in cooler roof panel. MSR lumber with 26 ga. steel skin on each side. I have analyzed the system as a composite panel system, neglecting insulation material, and have determined allowable stress has been satisfied. I have been provided with test data for these panels as well and...
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 appreciate all of the responses. The sign mfg. told me they usually weld the nuts on if requested, but they are hardly ever asked to do this in this situation. Sounds like someone isn't doing their job.
Thanks to all!
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.
JAE, that is a great thought. I thought about that but wasn't sure how feasible it would be, haven't worked to much with flowable concretes/grout. Definately an application to consider.
Would you suggest using removable forms or possible a metal deck form that could be left in place? Would...
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...
BigH, I understand that cost is not always the main driving force, however I am just trying to get to the point, like emmgjld said, so that I can ask the right questions. It is not my intention to become a geotechnical engineer, just become better educated.
It seems as though our geotech...
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...
No, I can try and see if he as any info regarding that. I doubt it though, he couldn't even remember if it was reinforced and i showed him the pictures we took.
I know what you are saying BigH, but some of the recommendations provided to us by the geotech. consultants are expensive. I was told by out expert not to take their recommendations as law, there will always be cheaper ways to remedy the situation. My problem is that I don't have the...
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...
