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...
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...
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...
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...
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...
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...
@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...
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...
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...
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...
Generally, I agree that LRFD should be utilized when performing ACI based anchorage design, but that is not the only available approach to engineers when designing connections to concrete. There are a lot of anchorage products which provide allowable shear/tension capacities. It is my...
Absolutely and generally, it is hard to find PDH's that are worthwhile. I try to line up the PDH courses to new topics or refreshers for items in my practice, and am often finding that lacking. Often the PDH requirements becomes more of a checkbox exercise than something that is beneficial.
There is probably an answer for bonding of the new structural topping concrete slab to the existing structural slab out there somewhere, but it may require a good chunk of research and follow-through on your end to get comfortable with it. If you do end up pursuing that, please follow up and...
That used to be my understanding, but that has wavered over the past couple of years.
Certainly in South Florida, the standard of care is to apply the ASCE 7-XX provisions for wind uplift for all elements of the roofing assembly.
Is it the intent for the topping slab to be typical structural concrete?
I would recommend taking at look at Miami Dade County's NOA's which are local to Florida's High Velocity Hurricane Zones which identifies additional standards for enclosure elements. In South Florida, Light-Weight...
In my opinion, yes I do think it would be dumb to take a pay cut - especially to go into a situation where you are likely to go into a higher stress, longer hours work situation.
I'd wager you should consider starting your own consulting business on the side (hopefully within your companies...
I tend to agree with KootK's approach, although I think the first step is to get everyone on the same page to figure out what has happened. As others have mentioned, it's possible the contractor would prefer to hire his own engineer to fix everything and it gives you the avenue to exit the...
