Hello,
We are working on a project which involves installing piles inside a tank compound. The compound has a clay liner as a floor and it has a berm all the way around. Since we'll install piles we'll break the liner and so I would like to seal the area around the piles. On a previous project...
Hello fellow engineers,
I have a structural problem involving a round HSS which I hope you may help me with. This is the situation.
1. There is an HSS406x9.5 column which will receive moment from a W310x97 as well as an axial load. The factored moment is 229 kN·m and the axial load is 33 kN in...
Hi fellow engineers,
I’m evaluating an existing shallow foundation, please see the attached diagram, and I would like to know if it’s logical to account for passive soil resistance in the “empty + wind” load case. Here is the background:
[ul]
Octagonal foundation (7’ feet, 7’-10” deep) has...
Hi fellow members,
I'm trying to design a pipe support but I'm not sure how to realistically model my idea. This is the situation:
I'm trying to attach an U-shape support underneath an existing platform. Welding is not an option. Due to the width of the existing beam flange, I can only get...
Hello fellow engineers,
I'm trying to design a bolted moment connection between a W-shape column and an HSS cantilever beam. The HSS beam would be connected to the flange of the W-shape. While looking at some books I noticed the HSS was always a column and never a beam. Does anybody know if...
Hello fellow engineers,
I'm trying determine what caused the corners of a concrete support to crack. This is a 40 year old concrete structure supporting a vessel. It looks to me like bearing failure. However, my calculations say only 30% of the concrete bearing capacity is being used. I've...
Hi all,
Currently I have a problem finding the moment resistance of a connectio in an existing concrete struture. While it may sound easy, my results don't convince me. Attached is a sketch and this is a description of the problem:
I am analyzing existing concrete frames. These frames are...
Hello,
I am trying to connect a vertical member (double angles are connected to a gusset plate which is connected to the steel plate I am trying to design) to an existing concrete beam. What makes this connection different to me is that no bolts are to go into the concrete. To achieve this I...
Hello folks,
I am trying to design a steel column to concrete beam connection and since I have never done this I am very unsure as to how to do this. Here is the background of the problem:
1. A steel column is to be installed between two existing concrete beams as shown in Figure 1. The...
Hello folks,
I interested in removing the roof of a building as this is the only way to put new equipment. Because of this I need to analyze the problem and see whether the building is stable while the roof is removed. In parts of the building I must take out roofing panels, and perhaps in...
