Bridge Company increased the deck pans to 18 gauge so we would meet single span requirements and we drilled holes in the pans to fit over the shear studs which do fall in the valleys of the pans.
We have a steel tube truss bridge 14' wide by 130' long that has floor beams 7'-2" o.c.Bridge had to be galvanized and painted so the nelson studs where installed before galvanizing 1' o.c. across the floor beams.Bridge company sent out 2" non composite 20 gauge deck pans which we flame cut...
Well the redundant issue has been resolved,the Owner's Engineers who were so adamant that it was required and they couldn't live without it have decided we don't have to suppy it.When asked to supply us with a detail drawing of this redundant chord which differs from the oringnal standard steel...
Thank you for your comments which we agree with,from what i found out the design Engineer drew the plans for a pedestrian bridge and then the County put the specifications together using their boiler plate highway bridge specification.The pedestrian bridge is being made from a company that...
I have a plan showing a pedestrian steel truss bridge showing a bottom chord of 8"x 8" steel tube.Specifications read "The steel truss shall be designed to include a redundant bottom chord comprised of double channels"
Can anyone tell me whats that means since the drawing doesn't depict what the...
Can't scaffold up from the bottom due to the steep slope project is overhanging a cliff with no access except from the top.Thats what we thought to hang brackets from the I-beams to support planking or picks to we can access 20 to 30 feet at a time and then be able to slide it to the next bracket.
We have a steel frame deck 80 feet above the ground. The W 30 beams are five foot on center and before we put the steel deck down and pour the floor we have to install all the piping on the underside of the beams.Can't use a lift underneath the deck due to the extreme slope so we have to hang...
Geogrid lenght for a Anchor Concrete Block wall ,is 60% of the height of the wall safe enough? Placing it on every other course 16" oc.max height 11 feet
angle of tie back is 30 degrees and 60 long to hit the good material below.We drove two master piles in down to 50 feet and around 40 feet we hit good material and the hammer had to work.We are also welding the other sheets together.Next step seems to be to weld clips to the sheets and anchor...
We just constructed a sheet pile wall in front of a exsiting concrete seawall on piles.There is six foot open space between under side of sea wall and grade.Engineer had us fill in with sand the lower three feet which then three feet of concrete will be poured to underside of seawall to prevent...
We are driving PZC 13 sheets with vibro hammer in the Newark Bay along the Bayonne shore line.Owners enginner specified a 25 foot long sheet.Then we have to drill grouted 2" hollow bar tie backs at 30 degrees ,60 ft long.As we drive the sheets the others that are set to grade are sinking several...
Thanks,alot of variables which we were sort of told by the manufacture also.Trying to sort through the temporary/permanent classification of these products.
Question, Williams Form 2" hollow bar grouted anchor galvanize and installed as a tie back on steel sheeting marine application.... What would be the expected life span on the anchor?
Thanks for all your replies,and yes we have poor soil conditions down to 25 feet before you get into the good sand so the 30 angle works the best to get to the good sand.Engineer of record no longer works for the design firm that supplied the bid drawings.All quotes for the anchors were based on...
We bid a projet for installing 25' long PZC 13 steel sheet piling with grouted hollow bar anchors 2".Bulkhead application with 12' exposed to the bay.Design Engineer plans show detail drawings as such and he noted the anchors to be 12' on center maxium with a waler.Wall design for 7000 psi per...
