Hello,
Could anyone possible suggest a resource to help determine the pile capacity of an end bearing pile based of the allowable load? The allowable load is 800 psf and was unsure how I would be able to calculated the allowable pile capacity. The drawings that I received did not indicate this...
BAretired, Yes, the drawing you showed is what the Port had installed. They used a W5x19 as a micropile and our senior engineer agreed that it wasn't providing much support which is why we were trying to see how much it can actually hold.
JoshPlumSE, when I built the section in RISA sections, I...
Is it possible to overlap members in RISA 3D to simulate a composite member? I'm trying to make a section where it's a wide flange enveloped by an 8" diameter round concrete. Originally, I had a built up section in RISA Sections but I realized that modulus would have to have been different for...
Hello,
Does anyone have any experience with the Cordaflex SM-RS? The cable we were using (Spreaderflex) just shorted out and the only replacement we have is the Cordaflex SM-RS. We have basket configuration and was worried if the Cordaflex would be compatible with this configuration. I know...
Tomfh,
I have never used another factor for the retaining wall. The most I have changed it is when I use the ASCE load combination which gives me a factor of 1.67
I've been trying to find the typical safety factor for overturning for a retaining wall. IBC states that the minimum overturning safety factor was at 1.5 but I had a talk with one of the geotechs that I went to school with and he had told me that the minimum for overturning is 2.0 and that 1.5...
Greetings,
Would anyone happen to know the typical Liebherr RAL numbers? I'm currently involved in a project that includes touching up the paint of the ship-to-shore crane made by Liebherr but the drawings that came with it did not indicate the top coat color. It's not the typical grey and...
Greetings,
I would like to receive guidance in checking bending stress for multiple plates in the same plane.
I have three keeper plates with weak axis bending due to an axial load. If I to were use a plate thickness of less than 1, the section modulus becomes smaller since in weak axis...
Hi Jim,
It's a ship-to-shore container crane that we will be using at Fernandina Beach. The codes we were using are ASD 14th edition by AISC, FEM 1.001 3rd edition, CMAA Specification #70. I'm just trying to find the right load case for the stability report. We have it listed as dead load +...
Greetings,
I'm trying to find the code that has the Minimum Crane Stability. The only information I have is that it's from a Technical Specification Section 4.4 and I can't seem to find it. The reason I'm looking for this code is because I'm trying to see if the Lifted Load (LL) and Stall...
jraef, thank you for the more detailed explanation. I do just want to ask about the FLC. Wouldn't the FLC be at 302A since 170kW is only at 227HP, and would use the 250HP value for it?
So for the conductor sizing, I would need to size it for 125% of 325A which is 406.25A. Is that correct?
Just a follow-up question, someone also mentioned about sizing the conductor based on the percent overload of the motor from the motor torque/current of the duty cycle. I thought that the...
I'm quite new to the engineering field and I was told to check if the sizing for the motor was done correct. The motor was a 214KW 480V with FLA of 330A. I thought that since the motor only had an RPM of 1000, I would need to size the conductor for 125% of the FLA and not the FLC. I was later...
