    How To Handle Jobs In Progress When Closing Business

    @human909 Agree that ethical and contractual obligations are huge considerations. I want to do right by my clients and make the transition as seamless as possible for them, but I’m also curious as to what exactly my legal obligations are. For example, if I include Construction Administration as...

    How To Handle Jobs In Progress When Closing Business

    "Policy period" is bolded and defined earlier in the policy as the current one-year term, so I don't think so.

    How To Handle Jobs In Progress When Closing Business

    Thank you all very much for your input. Understood regarding the steps required to bring another engineer in and assume responsibility. I'll need to check on exactly what the tail insurance covers. My policy refers to this as an "Extended Reporting Period" and uses the language below. It's...

    How To Handle Jobs In Progress When Closing Business

    I’ve been self employed for the last six years but am closing the business to pursue a new opportunity. I’m looking for guidance on how to handle the following scenarios. 1. Drawings have been permitted, but construction has not started. Am I required to remain involved for construction...

    Internal Gusset Plate Forces

    Yes but rather than the flexural stress being distributed in a linear elastic M/S fashion I believe they assume a rectangular plastic stress distribution with a moment arm of L/2.

    Internal Gusset Plate Forces

    Total shear and axial forces are distributed uniformly across A-A. The moment across A-A is considered to be resisted by an axial couple distributed uniformly across L/2 on each side of B-B. Add these forces that occurs over L/2 to the FBD in Figure 4-7. That should give a a complete FBD that...

    Correct design and detailing of X bracing in the middle Brace-to-Brace connection? (one story, so not beam there)

    X-bracing that resists tension and compression is permitted in SCBFs. If you can track down the 2000 IBC SEAOC Seismic Design Manual, there is an x-braced frame example in Volume III. However, I'd recommend using a chevron configuration if you can. It's generally much more economical than...

    Axial capacity of HSS with slender elements per ASIC 360-22

    Follow E.10 from the attached design examples.

    Perimeter Deck Attachments at Protected Zones

    You don't attach the bent plate to the protected zone. It either hangs free or spans over the protected zone to an outrigger on the column. For deck attachment you can use puddle welds or shotpins up to 0.18" diameter (AISC 341-22 I2.1). Fasteners may encourage more ductile behavior in the...

    Diaphragm transfer forces

    @RipPECity Read this thread and report back if you still have questions: https://www.eng-tips.com/threads/collector-design-force.512008/

    Diaphragm transfer forces

    Depends on whether the diaphragm is flexible or rigid. If flexible, the reaction from the wall above will flow straight down into the wall below. If rigid, all of the wall reactions from above get thrown back into the floor and are redistributed to the walls below based on relative stiffness...

    Guide to the Design of Common Irregularities in Buildings

    Completely agree on Sabelli. I bought the previous edition when it came out. I don’t have it anymore, but I recall being somewhat disappointed by its lack of depth and overlap with other publications. If you’ve got the SEAOSC Seismic Design Manuals and Bluebook and have seen some other design...

    Seismic Design of Mid-Rise Buildings with Heavy Rigid Floors and Light-Frame Walls

    Can you elaborate on why you think this type of construction doesn’t comply with IBC? I’d think the only issue is that you wouldn’t qualify for some of the exceptions in the code that are allowed for “light-frame construction.”

    NDS Table 11J for lag screws

    Late to the game, but I ran ran your connection through my spreadsheet and got 249 lbs, rounded to 250 lbs, which also matches the value I see in the NDS tables. By "no threads," do you mean that you are using the full-body diameter for the lag screw? I don't think that's possible since you'd...

    Shear Friction at Monolithic Concrete Confusion

    Yes, one could interpret that to mean any conceivable plane, but that seems unrealistic.

    Shear Friction at Monolithic Concrete Confusion

    Typically at transitions from one element to another or at a change in section.

    ASCE 7 22 Supplement 2

    As far as I can tell, Chapter 35 of the Florida Building Code only references ASCE 7-22; no supplements. As opposed to, for example, Chapter 35 of the California Building Code, which references ASCE 7-16 with Supplements 1, 2, and 3. You may be able to wait until the next code cycle to...

    Eccentricity in Column W12X72 to Beam W33X118 Shear Plate Connection with Stiffeners

    This article discusses shear connection design when stabilizer plates are used: Link. The bolt group can be designed with a reduced eccentricity if the stabilizer plates are sized accordingly.

    Masonry Subject to High Sulfates

    Thanks, JLNJ. I did briefly look into adding silica fume to increase sulfate resistance, but ultimately the contractor decided he would rather waterproof both sides of the wall and use standard block.

    Masonry Subject to High Sulfates

    Thanks, BA. Since the masonry standards are silent on the issue, I called a major local block supplier to get their input. The rep I spoke to said that there are some local cities that require blocks be produced with Type V cement for municipal projects, but outside of that he has never seen...
