    SI vs. Metric vs. US Reinforcing Call-outs

    Good question. As an American I haven't seen drawings in metric much but am actually working on an international project right now. I am not certain but I have also seen it called #25M or 25M.

    Forces Acting on a Pipe

    I am a recent graduate engineer. Sorry if I broke the terms of the message board. I think I have an idea of what I am doing but am soliciting opinions on the design and trying to see if there might be a better way to do it. I think the feedback I got from here (inserting concrete in and around...

    Forces Acting on a Pipe

    I am still sort of confused on how to calculate the capacity of the pipe. Could I consider this as a Round HSS filled with Concrete (AISC Table 4-17)?

    Forces Acting on a Pipe

    I am sorry, I haven't provided too much information. This is a open question and I am looking at different options of best achieving this. I think it is a great idea to have a concrete dead man type of situation. And it also prevents the steel from corroding in the long term. So you think it...

    Forces Acting on a Pipe

    Yes JAE, I was thinking that too. But how can I check it mathematically and approve the design?

    Forces Acting on a Pipe

    Hello, I have come by a problem that seems simple enough but has me stumped. Please see attached image since it is easier to understand. I am trying to use a 8" DIA Steel pipe as a transition point. I have rebar in a U shaped fashion wrapping the pipe in either direction and evenly distributing...

    Shallow Foundation for a Concrete Column

    There is definitely going to be an underground deadman anchor at either ends of the bridge where the cable will be finally tied off. But looking at the cable on the saddle situated at the top of the tower there are two different angles, one for the incoming cable (from main span) and outgoing...

    Eccentricity Check For Spread Footers

    andysines, you should look at this post http://www.eng-tips.com/viewthread.cfm?qid=310522 . It discusses a similar concern.

    Shallow Foundation for a Concrete Column

    All, thanks a lot for your input. As an EIT, I am pretty new to this stuff and all your help is greatly appreciated. Based on the comments I have changed my loads to unfactored and placed my foundation 5ft under ground to further stabilize the foundation. So my eccentricity has gone down to...

    Shallow Foundation for a Concrete Column

    Large dynamic movements in these type of bridges is common so unless we can provide a frictionless top on the tower there will be friction forces present.

    Shallow Foundation for a Concrete Column

    Yes, its a two column tower. The suspension cable slides along the top of the tower so I am assuming 25% of axial load as a friction load acting parallel/longitudinally to towers. (See attached sketch). So, putting a grade beam between the two columns will me strength laterally but not...

    Shallow Foundation for a Concrete Column

    HOOKIE66 - Trust me, I have verified the loads numerous times because it seemed too high for my understanding too. This is for a suspension bridge tower in a rural area with a wood deck. The load in the column (live+dead) is considerably low compared to the lateral force which is causing a great...

    Shallow Foundation for a Concrete Column

    Hello, I am designing a shallow concrete foundation for a 2ft x 2ft column. I have a concern because my moment (450 ft*k) is considerably greater than the axial load (70 ft*k). This is creating a large eccentricity at the base (e=450/70 = 6.4ft). To make this work on a shallow foundation I...
