I am currnetly in the process of designing debri shielding for a bridge. The exterior parapets and some of the deck is being removed. The exterior portion will be supported by overhang brackets and the interior bay will have wooden 2" x 12" planks resting on the bottom flanges. My basic question...
First of all I would like to say thanks to everyone who responded. I have considered all of the advice and I have taken a few steps already. I have on order the pile buck design manual and SPW911 program as suggested. I have also begun developing my own spread sheets based on the LFD AASHTO...
I have recently been given the assignment of helping a local contractor with temporary sheeting and shoring design. It's been a few years since I have worked in this area of engineering and I'm just looking for some helpful hints to get me on the right track. When tackling a new design process...
Recently I submitted an H&H report in which I modeled a culvert as a bridge in the HEC-RAS computer program. I recieved a comment back that it should have been modeled using the culvert editor within HEC-RAS. I have always been under the impression that from a hydraulic perspective the...
Thanks again for all responses. Now that the rehab of the beams looks more and more improbable I know the client is going to want an estimated design life of the structure in it's current condition. One rehab option is to simply blast and paint the beams but this is very costly and by the time...
Thanks to both of you. This web site is great. Sometimes even if you think you know something it's always good to get some feedback from other engineers. In this particular case I will develope cost estimates for different alternatives but I think I will make the recomendation that any slight...
Thanks for the reply! You have confirmed most of my feelings on the matter but one thing is still a mystery to me. How do you typically go about jacking a bridge like this? Would you go to the midspan and set jacks under diaphragms or the bottom flange of beams? Do you jack the bridge up the...
I have a situation were a bridge has two beams badly rusted at the bottom flange and the bottom half of web. The only "rehab" options that seem cost effective is either to bolt on angles or weld plates to build up the girder. Generically what is everyone's opinion on bolting vs...
