I have a question regarding the use of Mud Mat to meet the design excavation level.
I am working on a deep foundation that is laying on slightly to none weathered bedrock. The excavation involved blasting which resulted in some areas that were over excavated approximately 5 feet below the...
I need to do some aluminum beam design and had some questions on Aluminum Design Manual(ADM) Part VI Table 2. This table shows the allowable stress but is shown as F/Ω. It does not specify what the omega value is... Does anybody what the over strength factor that is used?
I am in the process of designing a steel pipe column that will require inserting a new smaller column inside of an existing column to increase the allowable strength. The smaller column will have an outside diameter 0.2" smaller than the larger column's inner diameter.
If I were to treat the...
I have an 11' existing cantilevered pole that is embedded onto the ground. I would like to brace the column somehow and was wondering if there are any ways to laterally brace a pipe column at the mid height. Will it be possible to install a seismic clamp and attach a high strength rod? The pole...
The solar panel is governed by wind force and I was wondering if the minimum reinforcement also apply to foundations governed by wind force. The pole footing is 5'6" deep and 30" wide. Are there any codes that specify pole footing reinforcement?
I am having trouble finding the right method in calculating the wind load and the net effective area on a solar panel that has a 45 degree slope. This will be attached a to a cantilever column. If I were to use ASCE 7-10, should I calculate the wind load as a solid sign or a sloped roof? Or is...
Trying to see if there are any specific deflection limit for a 10' cantilever steel column supporting a 6'x 6' solid sign. I am considering L/120 since this is an exterior member without any finishes. What are your thoughts? Thanks in advance.
I am designing a cantilever steel column with a solid sign and have not found an answer if I can apply the 0.6 wind load reduction for thr strength design. I know ASCE shows the ultimate wind speed and applying .6 converts it to nominal wind speed. Am I to use the .6 reduction just for...
Sorry if this is a stupid question but I was just really curious. If I were to just place a cantilever column for aesthetic purposes on the ground with only wind load being applied, is there another reason to check for deflections for the column if I used ASD load combinations?
I am working on an existing cantilevered column that has an increased lateral load due to the client wanting to install a bigger sign on the existing column. We want to minimize construction so instead of replacing the existing column, I was wondering if it was possible to insert a smaller HSS...
Hello,
I have a scenario where a client wants to have a cantilevered 2nd floor with a wide window with just barely enough room(17") for a hardy frame to resist the lateral force. Problem is that this portion of the wall needs to be supported by a steel beam underneath. I've seen details of hardy...
Hello,
I'm trying to design a two story concrete deck. I was wondering if there is a way to model one story and obtain all the final loads and automatically apply it the lower story using SAFE.
So I'm switching over to SAFE12 and I tended to realize that the number of rebars in SAFE 8 is higher than the number of rebars in SAFE 12 when I try to design a concrete deck. I was wondering if this is normal to other people who have been using SAFE 12.
For one of my models, I tried running a report after running it and for some reason the report stops when its creating Picture 2.... Did anyone else have the same problem as I did?
Hello! So I'm trying to add design strips to columns that aren't aligned in a straight line. Is there any way of approaching this method that also includes the middle strip and the auto width function??
