Your contributions for the last few years are of immense help to all of us. Congratulations.

bridgebuster - thanks a lot for the information. I will study them now.

Thank you all for your suggestions. I am not very keen to do this before getting a complete brief. My biggest concern is the connection, as kslee1000 has commented. Bridgebuster, any reference drawing will be very important for my design development and discussion. Please forward me the copy...

In order to achieve shortest down time, project engineers are requesting to explore the possibility of installing precast pile cap on a group of piles. Pile cap size will be quite large - over all size may be 3m x 14m. I designed pile caps before but never used a precast pile cap. A...

I had successfully used Microstran - MSTOWER program and Weisman - Guymast program in the recent past. I was associated with analysis and engineering of telecommunication structures for ten years.

hokie66, thank you for your response - this is what I am experiencing. Sorry, I could not respond earlier - my computer crashed! It is working now. Regards AM

It is quite common to have thick slab [800mm to 1200mm or more] foundation for heavy machines in minining sites. In such cases we should use low heat cement. Theoretically, special form work with heat insulators are required for such type of massive pours. I have not seen any low heat cement...

I have been using SpaceGass and Microstran in Australia. They both have some limitations but quite brilliant for general structural analysis purposes. I have not used design module of SpaceGass and therefore can not comment. Steel Design module of Microstran is quite good and complies well...

Thanks DBD, no ill feelings. Cheers AM

Wopshistos Thank you very much. This is a valuable documentation. Regards AM

DBD Sorry, I could not get back to you earlier. In the mean time I noted that dbuzz has given some of his input and I was going to write the similar thing. To my understanding this forum is for sharing the vast knowledge of all the people who participate in discussions and we all mutually...

DBD Thank you for your comments. Personally I do not have any satisfactory input in this subject. I will run this discussion with my other industry colleagues/peers and will update on this subject if I get any feedback. Regards

Thank you all for your responses. It is interesting to know about the practice in the USA also. We will stick with the running practice of 300mm then.

dbuzz Thank you very much for your input. We do exactly the same thing as you explained. I am looking for any technical reference to justify this approach. Regards AM

We generally provide 14mmØ grout hole in a base plate when the base plate size gets bigger than 300mm. To my understanding, this comes from accepted industry practice. I am wondering, if there is any published document where I can find the proper recommendation on grout hole size and the...

I would strongly recommend to read the following standards to start with. AS3995-1194; Australian Standard BS8100 [Part 1 and 4 mainly]; British standards ANSI EIA/TIA-222-F-1996 [I am not if 222G has been issued yet] Also, MSTOWER program, WEISMAN - Guymast programs for analysis and design of...

dbuzz Thank you very much for your quick response. Probably I have to purchase them from their web page. Regards AM

Big-H Thank you for your suggestion. Soil is well compacted granular soil, Ø is about 30°. I did not run any numbers yet, but looking at the pump foundation indicates they are quite substantial and will provide good damping. However I do not have the pump details yet and can not confirm my...

Hello Can any of you guide me towards any available paper/document on how to calculate loading effect from stockpiled material on the underground vault in a mining environment. Thank you in advance for your assistance. Kind regards AM

hello every one I have been reading with interest this valuable post and noted all interesting recommendations. I have a problem of a different nature. I do not have any experience in tank design but this is definitely a very interesting subject. We have large process water tank, 26m...
