    Subdivision Work - Pricing

    I think your fee here should be relative to the professional liability; but the terms and conditions of your contract should limit your civil liability. Construction Administration services should be hourly, as those may not be repeated at each location.

    IEBC Allowable 5% Gravity Increase on Total Load or Load Type?

    The Florida Existing Building Code also has the following section: "[BS] 707.3.2 Roof diaphragms resisting wind loads in high-wind regions. Where the structural roof deck is removed from more than 30 percent of the structural diaphragm of a building or section of a building located where the...

    Impact of Abandoned Pile on Pile Group Behavior

    My official position on this would likely be to have the Project's Geotechnical Engineer comment on the condition and provide any required remedial action. I believe the 3 diameter spacing is primarily related to the Geotechnical capacity of the pile - i.e. making sure you have a sufficient...

    Windloads for a building in a building

    Jae do you have a reference in ASCE 7 for that? I still see that as a live load in 4.3.4

    IEBC Allowable 5% Gravity Increase on Total Load or Load Type?

    I would consider total load as well. With roof live loads decreasing to 20 psf from 30 psf, that is an easy location to find some additional SID capacity in renovations... The existing building code is really poor in it's wording. I find designers have wildly varying interpretations and AHJ's...

    Legal Thoughts on Stamping Plans

    This may vary from state to state, but when you sign and seal you are saying that this works was prepared under your supervision. If there is an engineering error, that would be your engineering error. There may be some more wiggle room in civil liabilities for omissions depending on your...

    Easy foundation work or a trap?

    Is there any such thing as "easy work" in structural engineering consulting?

    Best Software for Full Concrete Building?

    Another vote for ETABs for Vertical and Lateral Frame Resisting Concrete systems. SAFE is reasonably okay for foundations, less so for elevated horizontal design. RAM Concept is great for both conventional and post-tensioned reinforced concrete design and ,in my opinion, is the best software at...

    The dangers of software and code changes

    Agreed entirely - but there seemed to be no reason to just not keep the 1.6 factor to scale up from an allowable/service wind pressure. South Florida has a NOA approval system for exterior enclosures. Windows, wall assemblies, etc are required to go through a pretty rigorous approval process...

    Tilt Up Panel Base Connection

    Thank you everyone for the insight. Looking back at the post and I noticed it does mention tilt-up construction. The detail identifies it as a precast panel - so in my head I imagined a multi-level construction with panels in-between floor levels. Would the group here still have the same...

    Tilt Up Panel Base Connection

    You are asking the erector to slide these heavy panels into these tiny dowels through a narrow hole. I expect you are going to end up with multiple bent dowels, followed by the erectors sawcutting the dowels. Would recommend an embedded plate in the panel and some kind of post installed...

    Lateral Loads due to Occupancy of Metal Decks/Ramps

    I initially thought of the grandstands and stadiums concept which phamENG identitified. The only other thing to add would be ASCE 7-16 1.4.2 Lateral Forces which provides for minimum required lateral forces. In Florida, we have no seismic load considerations. I have used these provisions for...

    Tension Pile Detailing

    Outward facing hooks are likely structurally beneficial due to the lack of reinforcement conflicts. In a number of different construction methodologies - outward facing hooks are a constructability challenge. In temporarily cased drilled shafts - outward facing hooks do not allow for the...

    Estimating CMU wall spread with scissor truss

    In a reinforced masonry construction - 3/4" cantilever deflection for your typical wall heights equals a cantilever moment that is generally smaller than your masonry wall out-of-plane flexure due to wind loads for a simply supported condition. With masonry construction typically having centered...

    post-tensioned ordinary concrete moment frame beam design

    From my understanding RAM Elements does not have any post-tensioned design features. I would assume that RAM Elements is performing the analysis assuming your beam is a conventionally reinforced concrete beam. It appears that you are utilizing a PT analysis tool (RAM Concept?) to design for your...

    post-tensioned ordinary concrete moment frame beam design

    @KootK I was primarily considering an interior condition when I made my statement, and should have clarified. In an end span condition, I would assume that the tendons would be lowered from the top of the beam to the center of gravity of the T-Beam section - reducing their efficacy in...

    post-tensioned ordinary concrete moment frame beam design

    You can consider your tendons at the top to contribute to your negative moment flexure capacity. I do think there are some good arguments to be made that you should have all of your capacity for your lateral demand load cases come from mild reinforcement. Likely to be the bigger impact, is the...

    Ethics Double Check

    What is interesting from this comment is that forensic engineers have a "conflict of interest" that is more significant than the one you are in right now!!! I think all of the risk here is related to the cost of litigation, challenges associated with repairs relative to new constructions and...

    Ethics Double Check

    I think there is a conflict of interest, but it's the same conflict of interest that occurs in every situation where an engineer is hired by the proejct's contractor. In these instances, I think the disclosure of the conflict of interest is what should be ethically required. If the owner wants...

    Wind load on a Retaining wall

    This is primarily a load path topic. If not by the retaining wall, how is the wind pressure on the stem wall resisted?
