    Underpinning

    I haven't designed underpinning, but I've been involved with it. For underpinning along shallow strip footings supporting basement walls, I would probably add dowels. For underpinning under shall footings near grade, I probably wouldn't. Check sliding since the underpinning will attract...

    How to sustain an Innovative Mind-Set?

    Fugeguy, you forgot your sarcasm tag in your second post! To be creative, just mimic what the musicians of the 60' and 70's did! (Just kidding!) I would also add break systems down into smaller pieces and see how each piece can be improved. It's hard to arbitrarily improve a system, but if you...

    How frequent is it for someone to leave the engineering profession

    People get bored with what they are doing and they leave. We put too much emphasis on finding a job 'that you love' that I believe empowers people to believe everyone else is doing what they love and, since they don't love what they do, then they must be in the wrong field. That's their right...

    [b]Wind: ASCE 7-16 versus 7-10[/b]

    Google it. Seriously, I found a couple of power point presentations given by consultants that explained a lot. It seems that new maps will be issued, like you said. Category IIi and IV will have their own maps and, I could be mistaken, category II and IIi buildings will have their wind speeds...

    Vestibule Drop Ceiling Wind Load Classification

    Maybe it's different for other parts of the US/world, but I understand a vestibule to be the 'airlock chamber' of the building - the small room used as an entryway before entering the lobby of a building. If that's the case, then it's an interior space and not subject to wind loads. Am I...

    Structural Engineering Detail Library

    XR250, I think bigmig means you see in the section is what is actually built instead of typical details. I think the BIM drafting details look better - the lines have rounded ends instead of squared. Personal preferences may be involved. The other problem with live sections in BIM is once you...

    Pressures at mid-height of building - ASCE

    Next time I will use a spoon to feed you. [rednose] Seriously, the wind guide has the information you are looking for. Cal91, I believe the design guides you are referencing are the AISC design guides, are they not? If they are, don't forget about design guide 30 (sound isolation)! PSEPK...

    OSHA/Safety requirement for ladder near handrail

    I second sail's response. No cage. Extend the handrails up to the same height as the handrails on the upper platform. I've done this before. The workers appreciate it.

    Pressures at mid-height of building - ASCE

    ASCE's wind load provisions are difficult enough for seasoned veterans in the structural field, so it will be very difficult to explain how to use the code to someone new to it. I learned wind provisions by having a more experienced engineer point out my mistakes, regardless of how much care I...

    PE Exam with Structural Breadth - Codes Required?

    Concerning the IBC, I only brought the structural sections with me to the exam. Chapters 16-24? I think that includes all of the structural chapters. I also brought chapter 15 - roofs - which I think I ended up using. I'm not 100% on that last bit, though. I don't know what volume 1 & 2 means...

    PE Exam with Structural Breadth - Codes Required?

    I had 2 questions that were quick look-it-up-in-the-code types for PCI. I think I had 1 requiring the AASHTO manual. Try to have the updated codes. I had a couple questions related to AISC and bolt shear capacities, which were updated in 2010. I'm pretty sure that there were more questions for...

    Professional Liability Insurance

    Check out ASCE's professional liability insurance for their members. I don't know much about them, but I have seen many people on here post about using them and they seem happy.

    minimum reinforcement for concrete duct bank

    I agree with the others. Chapter 7 of ACI 318 lists minimum area of shrinkage and temp reinforcement. The values vary between .14% and .2% depending on the grade of steel used. Also, don't forget your minimum clear cover and maximum reinforcement spacing.

    Looking for Archived Data on H.H. Robertson Wall Panel

    I would give them a call. Have them put you in touch with someone in their sales department. Contact information: Link

    Cable Clamps

    ASCE 19-10 is referenced in the ASCE and IBC. Section 3.3.2 of ASCE 19-10 roughly states the end fittings shall develop ultimate strength greater than the specified nominal cable strength, which means thimble type end terminations with wire rope clamps are not allowed. That's a squirrelly way to...

    Cable Clamps

    I agree with dhengr. General purpose wire ropes have a lot of stretch. You won't get near E=29,000ksi, so your deflections with rope will be higher. Also, the IBC and ASCE prohibit the use of clamps for cables resisting lateral loads or really any structural loads, depending on how you...
