The pipe is a buried one and is on still operational. The owner is the same client. I am looking for some standard from API of a safe distance to do construction.

I understand it depends on the country, but as per the construction guideline it is 50m. We don't have enough distance from the operating pipe to the construction place (means <50m). Hence we are looking for an American or European guideline for overcoming this criteria.

We are just proposing a soil test, but client is asking the above question of vibration before it. It is a driven pile of 400x400mm Piling will be done by a crane. Ground condition yet to be tested (on proposal). Can you brief CFA. Thanks for your response.

Hi Everybody, My client planned to construct a Tank foundation with piles near the existing plant. The issue is, what is safe distance to drive a pile to avoid vibration on the existing structures. I need this answer with a supporting document. Pleas help me with a solution!

Hi Everyone, I am facing a technical issue at a Brownfield Oil and Gas plan. My client wants to do some construction activity, but there is an operating Gas/Oil underground pipe near by. He is asking what is the allowable distance for safe operation from the Pipe. Please note that, he needs...

Hi, can you share your idea with a pictured example.

Hi Everybody, We have a existing Well-pad resting on the soil, and there is a pipe at the center of the Well-head. The drilling ring will drill through the pipe (see the picture given below). We need to modify the existing depth of the well-pad for some technical reasons, and the following...

Hi, I had this confusion long back but found the answer after a long time. To see the same base plate can be considered as pinned or fixed based on you assumption. Case (I) When base plate is considered as pinned. When the base plate is considered as pinned the moment on the...

Hi, I have a pipe rack of length 10m x width 5.7m x height 2.5m. It has plan brace as well as horizontal bracing as shown in the picture attached. The columns and the vertical brace are of HE 300B and HE 180A. The Pipe Rack supports a pipe which is anchored to the transverse beam(HE400A). The...

Hi Everybody, I have a base plate with Stiffeners and Anchor bolts. Please help me to calculate the base plate thickness when the middle anchor bolt is subjected to tension and has stiffeners on its both sides as shown in the picture.

Hi, So it will be nice if somebody gives an example how to evaluate the shear tab as a bracing.

After a long research I got the answer.The direct answer is given in Euro code(Joints in steel construction SIMPLE JOINTS TO EUROCODE 3), please find the references below. Thank you every body.

It is a beam

Hi Everybody, I have a channel simply supported between the columns as shown in the figure attached. The channel is connected to the column flange by a shear tab or fin plate. (i)As per AISC 360-05 clause F1 "The provisions in tis chapter are based on the assumption that the points of support...

I have three Spread Footing Foundations FD1,FD2,FD3. The Height of the Foundations H = 1.5 meter. The spacing between the Foundations are L1 and L2 = 0.5 meter. My foundations are weak in sliding, hence I am taking the benefit of passive resistance of soil but you can see that the clear distance...

Hi, I need to know the minimum depth of Embedment below the Anchor Bolt also specify the reasons behind it. One of the factors is side face blow out.

It means the T beam doesn't have any torsional capacity. I can understand that the couple is formed from the web and the flange. What does the top flange do in this case?

Hi I have a shear tab connection of HE400 A (European Section) longitudinal beam with HE300 A column as shown below. The cross looks like this When some pipe supports are supported on the longitudinal beam, as shown the picture above shall cause torsion on the beam. The beam is...

Hi, I have a simply supported I-beam, connected by fin plate connection. Will this beam can take torsion. As per AISC design guide 9 simply supported beam takes torsion. According to me this beam will never take torsion. Please correct me.

Hi can anybody explain with picture about the angle design procedure as explained by aisc 360-05. please explain me about the picture in detail.
