Hello Engineers,
I am designing an extended end plate moment connection using W12x26 framing into W10x33, W10x39 or W10x45 columns. On page 18 of the Design Guide 4 Extended End-Plate Moment connections 2nd ed., there is a requirement to use CJP (Complete Joint Penetration) weld if the flange...
Hello All Civil Engineers,
I have to design a containment area large enough to contain the rupture of 3 12-foot diameter and 20 feet tall tanks. The volume of the containment is for the content of all three tanks content (not a typo), plus the freeboard corresponding to a 25 year, 24 hour rain...
Since ASCE 7-10, the wind load is strength level for 1.0 Wind. For pipe stress calculations, do you use allowable stress design or strength level wind loads?
In COMPRESS Pressure Vessel Design Calculations, which is a Mechanical discipline related function, there is this section:
I have...
Fellow Engineers,
First of all, let me wish you all happy holidays and enjoy your time off.
I am looking for suggestions to connect square precast concrete piles to steel pipe rack base plate, using a Sonotube to cast the pedestals on top of the precast concrete piles. My concern is for...
Based on ASCE Task Committee on Wind Induced Forces publication Wind Load Design for Petrochemical and Other Industrial Facilities (WLD for POIF), 2020, Section 5.2.1, the tributary area is based on diameter of the largest pipe, D, plus 10% of the pipe rack width, W. I have a series of pipes, 10...
Hello Engineers,
Do you have any suggestion on which product to use to repair cracks in the existing containment? I am not sure where are the leaks but I presume it is around the containment wall that is leaking. I would think using epoxy adhesive is too expensive and thus not practical. Any...
When you quote a reference from either ACI or ASCE, please refer the code first, the year of the publication and then the correct section. That would help us in getting to the correct reference much quicker and saves time. Instead of just saying 7.10.5.1, the preference is ACI 318-11 7.10.5.1 as...
I am working of a project that has at least several hundred piles. It seems the helical pile contractors are not very responsive. Is that typical in that industry? The concept of screw pile / helical pile is fairly new to me. These guys are either slow or irresponsive. It does not look like they...
Dear Engineers,
What is the best way to print the forum threads for keep sake? I have noticed the names of the posters disappeared if I print to Portable Document Format (.pdf) using Edge. So it is hard to keep track on where the posts ends, unless you turn background graphics on. I have tried...
Hello Engineers,
I have a tall vertical vessel foundation to design. It is an independent vertical vessel on a octagonal pedestal and an octagonal pile cap. The number of piles is 12 numbers of 18" diameter auger cast-in place piles, 60' deep below grade. The choice of software available for me...
Dear Fellow Civil Structural Engineers,
I have to design a foundation for a tall vertical vessels. The anchor bolts designed by the Mechanical Engineers or Vessel Engineers are 2 3/4" diameter F1554 anchor bolts. I am new to this material and thus I need some help to verify if the calculations...
