    Opening in Column Base Plate

    Contractor on my project is asking if he could have an opening in base plate to run some conduits. Is there any calc that anybody could share which I can use to check my base plate design incorporating the opening?

    Bolts in Bearing and Shear

    Engineers, If I have a beam sitting on top of column with four bolts that are in bearing and take shear (no uplift in my case), should I just check bolts capacity in bearing and shear separately based on AISC tables or is there an interaction that I need to worry about? I know I need to consider...

    Chicago Building Code 2014

    Could anyone let me know what building codes are referenced in the new Chicago Building Code 2014. I need to buy one! Thanks.

    Structural steel repair

    I am involved with billboard renovation project. The owner wants to reuse the exisitng steel columns. But they are a bit rusted. I'd like to know if there is any place where I can send those columns to where they can be scraped off the rust and prepped appropriately and make it like new and re...

    Pour Strip through PT neams

    What should I consider when designing Post Tensioned beam with pour strip in it? Can anyone provide typical detail or design info? Do I design it just like a regular beam as id there is no break but provide pour strip where the tendons stop at CGC of concrete section and call it a day? How do I...

    Cast-In-Place Embed Plate with Studs design Spreadsheet

    I was wondering if any of you could share any spreadsheet that you may have to design embed plate with studs for steel beam to concrete connection. Has anyone tried using other procedures other than D.3.3.4 (ductility controlling design) for seismic considerations? If I were to use D.3.3.5, how...

    Steel column below slab-on-grade

    Are there any concerns with extending structural steel columns (Fy=50ksi) below grade? The footings on one side of the building are 7 feet lower than the rest and so, I am taking my steel columns to the footing while the slab on grade is 7 feet above the top of footing. Is there anything I...

    Concrete edge beams

    Dear All, This has been an immensely useful thread even though I think my understanding on compatibility and equilibrium torsion just got better. But this thread actually got me thinking further. Say, for example, I have a cantilevered slab with a back span. Now, can I say that the equilibrium...

    6-Story Braced Frame Analysis

    Sorry, I saw the attachment it looks wierd. If I assign just a column as a lateral member and do not assign any beams framing into it as a lateral member, I wonder how computer model would analyze it. What is the member that can actually transfer lateral loads to the column in such a case for a...

    Grade of Steel

    I am evaluating an existing steel structure for current loads. I modeled the structure only to realize that the whole structure is failing, while in reality the structure is doing just fine. There is not explicit note on the drawings saying it is Fy=50 ksi structural steel and hence, I modeled...

    6-Story Braced Frame Analysis

    Teckert: I think you are talking about dummy column as in "zipper column" in the V bracing system. This was developed by Dr. Leon from Georgia Tech University. I attended a seminar and he said he did some studies that showed that dummy column (zipper column, thats what he called) would help in...

    Influence of footing

    The other route I am thinking of is to just place a slab on grade and not worry about the footings, as I imagine under-ground box culverts have to be designed for any earth fill or even traffic. I do not know if I can count on that. Probably, what I need is to someone tell me what these box...

    Influence of footing

    There is a box culvert over which I am designing a one-way slab to take pedestrian loading (85 psf). I am also designing strip footings to support the slab. However, I'd like to take the footings to the bottom of the box culvert so that the footings do not impart any loads to the box culvert. Am...

    Differential Settlement of spread footing

    Thanks a lot people for your input. I have decided to use Meyerhof's formula to determine settlements based on the bearing pressures that I calculated to see how bad of differential settlements we are talking about. Somehow, the geotechnical engineer has not got back to me yet on this. But if he...

    Differential Settlement of spread footing

    I am adding a column onto an existing spread footing. It is not the bearing capacity that I am worried about but the differential settlement due to additional load that I need to check. Can someone enlighten me how I can check this? How much additional load on a spread footing (in terms of...

    Curved Concrete beam in elevation

    I have used curved HSS tubes before for a design that I did for a walkway. It looks like a space ship landing dock. Anyway, steel hot rolled sections are bent that way a lot of times and it is not unusual. I suggest you specify a curved steel beam. Make sure your connections are designed...

    Hilti HY-20 into hollow CMU IBC approval

    The way I have been handling epoxy anchors is as follows: I use Hilti tables for allowable deisgn. The shear capacity values, I use just the way they are. But tension capapcity values, I divide by 6. Do not use the ultimate values. There is a factor of safety of 4 in-built in the allowable...

    Hollow CMU through bolt capacity

    Why dont you want to use Hilti HY 20 for hollow concrete block? The tension and shear capacities are explicitly given in a Hilti product guide. I know some are concerned about using such anchors, but I use them all the time. They have been performing just fine.
