    FIU Pedestrian Bridge - EOR aftermath

    I see what you mean. The FBPE does have the authority to fine an individual as they see fit, but only a $5000 administration fine is codified. Not sure how they would arrive at other amounts. I'm not sure why, but the settlement agreement makes no mention of any violations of Florida statutes...

    FIU Pedestrian Bridge - EOR aftermath

    Yes; I mentioned this in one of my posts. We'll never know for certain his motivations for taking so long to turn over his phone, and it is impossible to prove that he had his phone washed on purpose. It's weak sauce though. It reeks of the EOR trying to hide any pictures he took the day he...

    FIU Pedestrian Bridge - EOR aftermath

    Okay, so what consequences do you want? Even if he didn't settle, the board could still do no more than revoke his license and bar him from practicing in Florida. The whole affair has been highly publicized; the NTSB squarely laid responsibility of the failure on the design engineers. The US...

    FIU Pedestrian Bridge - EOR aftermath

    I'm still surprised WJE stuck their neck out on this one. Their effort is somewhat commendable, but it was only a model of a portion of the bridge segment. A far better, though impractical solution would have been rebuilding the whole thing exactly the same way except including the roughing...

    FIU Pedestrian Bridge - EOR aftermath

    In the US, the engineering boards do not have the authority to file criminal charges against engineers. They can rule on licensure status based on what an engineer has done under their ethical and professional statutes. Why this EOR was able to settle versus having is licensure revoked, I...

    FIU Pedestrian Bridge - EOR aftermath

    I think that was part of the settlement. He had to turn over everything he knew about what happened. Waived all right to confidentiality of whatever he turned over to the FBPE. He had to fully cooperate. In return, he voluntarily relinquished his license and waived his right to reapply for...

    FIU Pedestrian Bridge - EOR aftermath

    I saw where it stated he retired. This is after a federal judge ruled against Figg and the EOR petition to temporarily stay their debarring from working on federal jobs in August 2020. I'm purely speculating, but his retirement and this subsequent settlement with the FBPE seems to be an effort...

    FIU Pedestrian Bridge - EOR aftermath

    thread815-477378 It's been very quiet regarding what became of the EOR on the FIU Pedestrian Bridge, and the Florida Board finally posted the reckoning. https://fbpe.org/pate-w-denny/ I figured there'd be a lot of us out there interested, and I was surprised it was so quiet. An interesting...

    Miami Pedestrian Bridge, Part XIII

    Ah. I saw the number 12 (and others depending on the strand designation) in front of the strand, but didn't connect it as the number of strands per conduit. Not very familiar with post-tensioning; looked up something and thought the number designation for couplers was for size of coupler. It...

    jrs_87, can you point me to what you are talking about?

    Miami Pedestrian Bridge, Part XIII

    I am still perplexed by the final continuity condition between the front span and the back span. Going back through the RFC plans, Tendons C1 and C4 are called out to be stressed after the closure pours between the front and back spans have cured to 6000 psi. There were 2 - C1 tendons and 2 -...

    Miami Pedestrian Bridge, Part XIII

    Earth, I can see where I am being misunderstood, but I am not saying that the structure as-is should have been analyzed as a prismatic section. I am saying that they used a complex system in the form of an open, strut and diagonal web for what, in a lot of ways, is an I-beam. Comparatively...

    Miami Pedestrian Bridge, Part XIII

    Earth314159, under uniform dead load (which is basically what the structure was under at the time of collapse), every single node had to handle shear, moment, and axial forces; a truss, by contrast only cares about axial forces in the members (get out of here, Vierendeel; you're not a real...

    Miami Pedestrian Bridge, Part XIII

    I also don't see how a lab test of an isolated member would be considered one-to-one with the full-size, complete structure. Like hokie66 keeps pointing out, that big beefy deck was being restrained by the twig like diagonals; that interaction doesn't get captured in WJE's test. Obviously, it...

    Miami Pedestrian Bridge, Part XIII

    There would be zero success with what the EOR thought would work. I have heard of remedial post-tensioning used to close cracks, but these are typically flexure cracks that have been arrested by flexure steel. They are just being closed for preservation against the environment. We're talking...

    Miami Pedestrian Bridge, Part XIII

    Yes, the final design details should have been based on the worst case of all stages of construction. What I don't understand is how would the back span have alleviated the issue. The only think I see the back span doing is restraining longitudinal movement of the main span. NTSB correctly...

    Miami Pedestrian Bridge, Part XIII

    Was a FEA even necessary here? Why couldn't a simple STAAD/RISA model be used instead? It seems a FEA over-complicated the issue.

    Miami Pedestrian Bridge, Part XIII

    Load Resistance and Factor Design typically specifies a 0.9 load factor as a lower bound for Dead Loads. I have seen this both in ASCE 7 and AASHTO Bridge Design Specifications. The intent is to use 90% of the dead load in instances where you are counting on dead load to help you. For example...

    Miami Pedestrian Bridge, Part XIII

    Did not know that about the wheel barrows; definitely a warning. As far as design oversight, I had thought it was still up to (and found to be so) the EOR to validate the fabricator's substitution, and, even without the substitution, the EOR had underestimated the design pedestrian load by 40%...
