I have a foundation slab that is 4'-11 thick (the total dimensions are 14 ft x 14 ft x 4'-11" thick) & I am wondering if Minimum Flexural Reinforcement ACI 318-19 8.6.1.1 is applicable to this foundation. The applied vertical force is 100 kips & an applied moment of 295 k-ft. This is an...
In PIP STE05121 Application of ASCE Anchorage Design for Petrochemical Facilities it says the following:
“In the case of larger diameter anchors, the only relevant applications for using a sleeve are to provide stretch length to meet the requirements for the anchor to be a ductile steel...
I have a project located in Clarksville, Tennessee & I have been asked about consideration for Tornadic Loads.
I used the ASCE Hazard Tool (https://ascehazardtool.org/) to determine if TORNADIC Loads shall be considered for Clarksville, Tennessee.
Based on the ASCE Hazard Tool, it seems that...
I am looking at 17.10.5.3a & I had some questions about iii., iv., & v. Could someone provide some insight about these subsections of 17.10.5.3a?
It seems to me that 17.10.5.3a part vi. is referring to using the adjacent vertical rebar to help resist the tensile forces. Could anyone please...
I am seeking a design example for an Anchor Bolt Design for Seismic Site Class C based on ACI 318-19 Section 17.10. I am seeking a design example that shows the various Sub Sections of Section 17.10 being adhered to & referenced.
If anyone has one, could you please pass it along.
Also...
Could anyone please let me know where it is mentioned to use anchor bolt sleeves for Vertical Vessel foundations? Is it in PIP or ACI? I am trying to find a reference on when to use sleeves for various equipment. I know that API RECOMMENDED PRACTICE 686/PIP REIE 686 talks about using sleeves...
I am doing a review of some checkered plate drawings & I am wondering if their is something like a PIP specification for checkered plates? I am aware of PIP STE05530 Grating Design Guide & PIP STF05530 Grating Fabrication Details. However, it seems that these specs do not really apply to...
I am working on a project & I am new to creating Site & Demo Sheets. The site for the project will be subjected to Risk Category of II and Site Class D Stiff Soil.
What considerations should be taken when designing storm & sewer lines for site preparation & demolition plan sheets? This is for...
For a Structural Engineer working on facility design as a lead engineer, which type of facility would be the most challenging to design out of these 3 types of facilities: chemical plant, refinery, or water/waste water treatment plant?
What would be the easiest type of facility to design out...
What is the span length to be used to design a Bond Beam for a one-story building? Would it be the same span length as the largest opening for the any required lintel beams?
Comments/suggestions are appreciated.
Is it structural acceptable to use a min. steel reinforcement ratio of 0.0018 for the design of grade beams when using Fy = 60 ksi & F'c = 3 ksi based on ACI 318?
Comments/suggestions are appreciated.
Is anyone aware of a design tool (i.e., spreadsheet, program, etc.) that could be used to Design CMU Walls for Gravity plus Out-of-Plane Loads?
It appears that an interaction diagram is required to carry out Designs for CMU Walls for Gravity plus Out-of-Plane Loads.

I am looking to verify the capacity of a cast-in-place reinforced concrete wall for shear based on ACI 318-19. I am seeking an example of this calculation.
Comments/suggestions are appreciated.
Section 11.7.2.3 of ACI 318-19 states the following:
It appears to be worded a little different from the ACI 318-14 version:
Would it be safe & acceptable to interpret that for ACI 318-19 code when designing walls thicker than 10 inches, we distribute the required horizontal reinforcing...
I have a pit that has a layer of stone & wood chips contained within. The walls are also retaining soil on the other side (see image).
Would it be best practice to apply the stone & wood chips contained within the pit and apply them to the wall as lateral pressure?
The height of the stone...
What is the unit weight of pulp grade wood chips? The wood chips are comprised of shredded hardwood tree species.

Is the POWER-BOLT Heavy-Duty Sleeve anchor manufactured by DeWALT a good product for post-installed anchorage into concrete? Please let me know.
Comments/suggestions are appreciated.
In PIP STE03020 Guidelines for Tank Foundation Designs, section 5.6.6.1 talks about the Minimum Reinforcing Steel Requirements for Ground Storage Tank (GST) Foundation.
In regards to the Concrete Ringwall foundation (see image below), what portions of the reinforcement are considered...
Would it be acceptable to use a soil report to design a retaining wall when the borings drilled are 3500 ft away from the retaining wall?
I would think an additional soil report would be required when the nearest boring is 3500 ft away, but I figured I would get another opinion...
