    STAAAD Pro - Force Envelopes of Physical Members

    I have a beam modeled as multiple beams to account for changes in section properties. I created a physical member from this group of beams. What I am trying to do is print the force envelope of that physical beam at nsections. Is this possible? Related question, but lets say that I'm only...

    HEC RAS - Modeling winding river in high flow conditions

    Before this gets out of hand, Yes, I realize the bridge is slightly skewed to the stream. However in the Hecras Bridge/Culvert Skew input, it says "In model testing, skewed crossings with angle up to 20 degrees showed no objectionable flow patterns. For increasing angles, flow efficiency...

    HEC RAS - Modeling winding river in high flow conditions

    Okay, I see what your saying. LincolnPE, I agree with you that I was too focused on the channel, rather than the plain itself. It was my thought that the xsecs had to be perpendicular to the flow. Either way, I don't believe the xsecs would cross the road because the river downstream runs...

    HEC RAS - Modeling winding river in high flow conditions

    Okay, it took me a while to understand why I would do that, but it makes sense to me now. Although the water will be in the overbank regions, it's still going to be somewhat stagnant due to wetland grass and brush, until the water gets high enough to start actively flowing. I would have never...

    HEC RAS - Modeling winding river in high flow conditions

    Oops, Apparently I don't know how to attache multiple files at once. The one above was the hec-ras screen shot and this one is the microstation screen shot. Also, as far as more x-sections below the bridge, I took it as far as we had survey data for the site. So I can't really go any further...

    HEC RAS - Modeling winding river in high flow conditions

    Thank you for responding Francesca! The study is for a private bridge replacement. In the state of Wisconsin, a replacement bridge cannot raise the upstream water elevation which the existing bridge gives us during a 100 year storm. So, I analyze the existing bridge, find the upstream water...

    HEC RAS - Modeling winding river in high flow conditions

    Alright, I believe I have the right idea now. Since I last posted, I ran a pond volume analysis to make sure check to see if I had enough storage to lower the water elevation. Turns out it fills up in little over 3 minutes, so that's a non-factor. I will definitely use your suggestion of...

    HEC RAS - Modeling winding river in high flow conditions

    Gbam - Thank you for responding! I understand that I can recut the sections in new locations, although am I uncertain how to lay them out. As you can see from the attached picture (hopefully it shows up!) the road has a slight horizontal curve to it. Would I place the x-sections completely...

    HEC RAS - Modeling winding river in high flow conditions

    This is my first post to eng-tips, so if you have any tips about forum posting, I will take them into consideration next post. I would like to state that I am relatively inexperienced in the civil engineering world. I just received my B.S. in CE in May of 2011 and have been soaking in as much...
