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...
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...
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...
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

I need to design a splice for circular hollow section; splicing will be with bolted flange connection for axial load coupled with bending moment. I have design guides for axial load only - but not for bending moment. I am looking for some guidance in this matter from any of the forum members...
I am designing some standard conveyor belt trusses. I got all the belt details, carry & return idler details, material loading etc. However, I am looking for any good reference for wind load calculation. The trusses, walk ways, cable trays, service pipes etc all have contribution in wind...
I am looking for some design example / guidance for the structural deign of different types of Chutes in material handling application, for example Crusher discharge chute, Screen discharge chute and other types of small or large chutes. I tried material handling forum but need more...
I am looking for some analysis tool to calculate the exact [as close as possible] length of guy wires for a very tall guyed mast. I believe guy attachment location on the mast will at about 250m, anchor radius will be about 180m. I anticipate guy wire diameter will be in the range of 75mm or...
Hi
I am currently reviewing a structure and noticed that the Yield strength of some of the main steel members is 90000psi [620 MPa]. These members are subjected to very high compressive and/or tensile forces. I never dealt with such a high grade steel and wondering if standard formulae of ASD...
Hi
I am required to upgrade a existing foundation slab by casting a new slab over it. Generally short starter bars are installed on the existing concrete in drilled holes (and using epoxy grout) to achieve good bonding.
My question is, how to calculate the tensile force in each starter bar...
I am looking for any web site or any reference book where I will be able to find the design wind speed data [3 second gust and/or fastest mile and/or hourly mean etc]for various [if possible, all!] major cities in the world. Please guide me where to find this information if any one of you aware...
I am looking for some information on how to calculate wind load for a pentagonal or hexagonal tower. All the relevant standards give direction for wind load calculation for triangular or square towers only. I am designing a special polygonal shaped tower and need this information. Any help...
Is there any text book which explains and provides worked out examples for designing off shore structures with API RP 2A? Any suggestion will be greatly appreciated.
