    Is it beneficial/recommended to have longitudinal reinforcement placed at the corners of stirrups?

    There are quite a few rebar on the top and bottom of the beam so support is not a question. So the question is about rebar placed at the corner or could be a few inches away? I have been detailing the corner but just saw some plans other than that.

    Steel Plate on top of Concrete Column?

    Can I have a steel plate with welded studs on top of a concrete column? The plate will be larger than the concrete column section. I have concern about how the contractor places and vibrates the concrete. Or they could insert the plate after concrete pouring and vibrating? Please advise. Thanks.

    Hec-ras Modeling

    Yes the water will be running away. It is weird that I compared "ineffective area method" and "Lateral weirs method" and the difference in WS is minimal and I still have a few feet overtopping.

    Hec-ras Modeling

    How can I model a river which is "in the sky" with Hec_ras? The bank elevations are higher than adjacent aeras so once it is overtopped, the water will run away perpendically to the reach. I was setting ineffective areas but it seems not working as the cals are showing the WS is a few feet...
