Thank you for helping me out. Do you specify or know of any certain manufacturer of the foam sleeve used for this application? Has this method been effective, both the installation and poerformance?

I wanted to ask if it is common practice to specify a polystyrene sleeve over the first 12” of a hairpin-type reinforcement bar that ties the wall footing into a concrete slab. I saw the detail used in an example problem in the book “Masonry Structures”, by Drysdale. It seems like a good idea to...

Thankfully this is just curiosity, I’m an EIT planning on taking my PE exam in the Fall. I read about the associated legal aspects of engineering design in trade magazines each month that attempt to define various situations. I have not come across a lot of information on the subject, which...

I was curious if anyone could explain how an engineer becomes personally liable for design errors on projects. I believe that a PE is personally liable in the US if they seal a set of drawings and a claim occurs. So does E&O insurance cover both the company as well as the individual? What about...

My question deals with the transfer of moment from the base of a tank wall into the tank slab. I know that this connection can be assumed closer to pinned of fixed depending on the reinforcement detailing. But, if this connection is assumed close to fixed, what kind of reinforcement is...

Thank you for your help, that is the info I needed. I understand of your reasons, both make this detailing practice very logical. I was originally thinking along the lines that it was to resist the shear created in the projection when any uplift type force was being resisted by the soil wedge...

I wanted to get some feedback on a mat foundation detailing observation. I have seen detailing of mat foundations with projections beyond the vertical walls having the top bars bent down along the outside edges in both directions. These bends along the outside act as a stirrup, closing the top...

Thank you arniec for some actual results feedback, it does not occur often. As a Robot Millennium user, I'm glad to see that the Robot results were very accurate. I have been a Robot user for 6 months now and have been very pleased with both concrete and steel model analysis and design...

A demo is available. See web site http://www.robot-structures.com/us/index.html or call 1-888-477-8491

After a complete review of many of these programs, I also decided to go with ROBOT. It has the concrete capabilities of STRAP, but includes many more features and is much more advanced at a lower cost. ROBOT also was the only company that actually demonstrated their program with an example that...

Are there any Robot (ISS) software users that might share some opinons of this program? This program seems to be very impressive, much more then most competitors. I don't know how wide-spread the use is in the US, but understand that it is number one in Europe. Thanks for your help.

Thanks everybody for excellent feedback. After some initial use of the SAP and STAAD evaluation copies I can see the drawback with the lack of design Mx, My. I will look further into STRAP as suggested for this analysis and concrete design. Any other/more suggestions would be great.

I agree with your view about the reliability of software not created by the user. But, STAAD claims that 75% of engineering firms are using their software, which seems very impressive. Also, when looking at structural job openings, most firms are looking for a STAAD backround. As a young...

My question is about which FEA software, with concrete plate design ability, is the best for the US. It seems that STAAD is the most popular and has the majority of the market. What are your opinions of STAAD overall and would you recommend buying it compared with competitors? I have reviewed...

Thanks jifbird. I am in the US(Ohio), so I will need to look into the US code support. I requested some demos, but I would like to know what software in this area you find most useful and effective? CSC seems to have a very complete software package line and TEDDS. True? Anyway, I thank you for...

Thanks for the helpful reply. Which General Analysis programs offer the best plate or shell analysis results? (which I would need for concrete design) It seems that steel frame analysis and design is the only major focus with most of the major software packages. So, I was wondering if anyone...
