Your best bet is to review a publication relative to lift slab construction. The bearing conditions of the lift slab procedure is exactly what you are concerned about.
According to many of the states' licensing laws, a professional engineer is required to protect the public safety. However, in practical terms this usually means that the professional engineer should bring the unsafe condition to the attention of the building owner, and then if the danger is...
There is absolutely no reason to cut control joints in concrete topping on single span plank.
However, at the centerline of supports where plank is butt-jointed, it is advisable to cut a control joint in the topping.
First, the brick wall should not have an air cavity between the two wythes. If it is a bearing wall, the collar joint should be filled with mortar.
That being said, I would grout the collar joint solid, and probably install through bolts and fish plates, unless the brick was in very sound...
If you have a partial composite beam, and apparently you do, there is absolutely no problem coring and adding steel studs to increase the percent composite action. We have done exactly this on several occasions.
Just core the holes large enough for the stud welder, and at least four times the...
It is actually a very common problem in many areas.
The easiest thing to do is to maintain a reasonable amount of water in the pool (in addition to the concrete weight)to counter the buoyancy.
Additionally, since there will undoubtedly be times when the pool must be emptied for maintenance, the...
Granted, this may be a little late, based on the date of the original posting (I don't get a chance to log on much), but . . . it can assist anyone who may be searching later for info.
The best information for design of the lifting frame is an article entitled
"Design and Construction of...
I recommend that you contact a company that manufactures single pole signs almost exclusively. They've got the design and the details down to a science, and the sign fabrication would likely be more economical.
And yes, I agree with Civilperson, a drilled foundation is usually the better...
Builders (and many times architects) have a problem understanding the wall thickneses required for higher walls.
I have found that the easiest way to explain it to them is as follows (tailored to your situation:
"Assume the wall is an attic floor, with a 20' span and a 20 psf live load. What...
JD2, I've got some practical, unpublished information regarding using remnants of prestressing strand in precast panels for lifting. The table was developed in 1972 by the chief engineer of Formigli Corporation, a well known precast manufacturer by whom I was employed at the time. The load...
Eng-Tips is a very useful tool. Since I first became aware of this site a couple of years ago, I have searched for answers to some of my questions, I have posted a few questions, and I have responded to a few questions. I only wish that I could respond to more questions, because I believe my...
Does anyone know of a good design/analysis software for designing pilecaps?
I've been using "TGPiles", by Digital Canal, but it seems that they no longer support it, and it is not really suitable for the Windows environment.
Like about GeoPro:
Easy to use.
Quick, similar to using a calculator, as opposed to a software program.
Variety of computations for a reasonable price.
Don't like about Geopro:
Not very flexible.
Limited input & output.
For your purposes, it sounds like Geopro might be what you're after.
I am...
I use it and they work fine.
You may also want to investigate Ensoft software for more detailed analyses, and Civiltech software which is also pretty good.
The IBC and all its predecessor codes require a 10 psf minimum wind load, whether indoor or outdoor.
Also, I agree with jstephen, if it is a people load, a min. lateral force of 10% of the live load should be used. Especially, if dancing, or similar types of movement is possible.
I have found the "Steel Smart System" to be a great cold-formed steel package. I also have the RSG software, but it was not as powerful, or versatile. It can perform the designs that you mention, as well as shear walls, curtain walls, trusses, etc., and provides a multitude of CAD details for...
Thanks iken,
LEN and DY work fine, I just wish I could find the command in the normal way.
I do not have a paintbrush though. Maybe I'll try to reinstall the software. I remember I did have some problems with the installation because of a structural overlay program.
Hope it works.
That's the problem. I can't find the commands in any list. They're not in a drop down menu anywhere, nor are they in a list in the command or customize windows.
