Precast structures have the complexity of detailing as steel structures and the design complexity of the concrete design. It really requires you to know all these complexities; this video will cover some of the structural design principles that you need to know when designing precast concrete buildings. This video covers precast columns, precast walls and precast floors. Precast structures do not know need to know about stress design but also need to consider the time behaviour of concrete and the locked-in stresses.

Great job on the precast elements. I do like you spend the time detailing the connections aspects which sometimes are overlooked. The methodology for connecting the two elements together. You also mentioned a key point on waterproofing the joints which can develop water intrusion. Stay safe Malik.

@dykodesigns Год назад

I regularly have to detail bridge decks and often the builder wants a precast solution with in-situ joints. In my experience this choice creates more complex rebar details as opposed to a full in-situ design. Mostly the splices and overlaps cause challenges as the joins can get crowded with additional stirrups.

Thanks for sharing this perspective I've limited experience to precast work but am beginning

@yekutielbenheshel354 Год назад

Wow! Great stuff! Thank you! This seems like the first lecture in an engineering course entitled, "Introduction to Precast Concrete for Structural Engineers." I can imagine successive lectures that involve discussions related to chemistry, physics, and working with builders.

Glad you enjoyed it!

I have been designing and detailing precast concrete for over 42 years. All of your points are very valid and valuable considerations. I think we as an industry have learned a lot over the past 50 years regarding detailing and design of precast concrete elements. Redundancy is a primary concern as well as unintended restraint. I think you covered that well. You have a new subscriber. Thanks for the video!

precast manufacturing doesnt affected by the weather, but in actual installation, if its a windy day and cranes are off you can't do much.

Hi Brendan, I am wondering can you do a series about Modeling structural Behavior in a analysis program ? I am currently requesting to do some structural analysis modeling but I have no idea the concept of Moment release when the seniors are applying to the model.

@noraalaoui9151 Год назад

Hello do u have please any guide documents for the design of precasted concrete constructions ? a report that shows the main steps to follow to design a precasted construction in concrete ? Thank you so much in advance. This would help me in my end of studies project.

@stranger2649 Год назад

Dear Brenden plz make full vedios on how you design the foundations, walls, beam , column and slab. Plz make full vedio one by one how u do design by a practical vedio which code u r using in and plz make me your student.

@john6yui Год назад

Hi Brendan, Can you please recommend a good book to learn design and construction of precast concrete structures ?

@impulzive Год назад

Great channel! I am an architect student from Norway, and I am learning more from your channel than what we learn in school. I got a project about reusing concrete slabs and elements. Can you recommend any videos/sources for connecting elements which are not precast to fit? Especially roof/floor to wall connection. Thanks!

@BrendanHasty Год назад

Hi Robin, I will make so of these in the future, but I dont know any off the top of my head. concrete is really easy to connect you may want to look at some of my concrete videos. thanks for the support.

@thomasmattson2389 Год назад

For precast one floor house do the same protocols apply. I'm trying to figure out how to design a very inexpensive quick to build low income house. Will be while to build, just want to learn and design some homes. Flat roof, on slab.

@cara5655 Год назад

Hi! I am trying to draw details for composite floor connection to precast walls, would you be able to advise on this? Do I just draw projected rebars that connect to the composite floor? thanks in advance

@zisongjia8622 Год назад

Hi Brendan, I am Jason from China, currently working on precast industry, typically joint solution between elements. In China, the design logic is "equal to cast in situ" shear wall vertical connection is grout sleeve while starter bars and post cast in horizontal connection, what do you think this type of connection?

@muditmishra1811 Год назад

What is your opinion about dry connections ?

@willcade5703 Год назад

Hey Brendan, I'm wondering if you have a video how to read civil drawings, specifically for asphalt and concrete paving.

Hi Will, I have done several drawings on how to read some structural drawings, however, I have not done civil drawings yet. I will look into it.

@willcade5703 Год назад

@@BrendanHasty awesome, I've been teaching myself what I can. One of your videos was very helpful to me in the past.

@CCSI322 Год назад

Never heard the phrase in-situ before. I'm just starting to inspect precast I've only ever been in-situ

@yekutielbenheshel354 Год назад

It's Latin. It probably helps to avoid confusion compared to "poured in place concrete" which would tend to be ambiguous in many contexts.

@Ooze27 Год назад

Great informative video like always. I use a lot of precast slabs in residencial buildings over here, it's good for some things, what i don't like is that it sort of locks the rest of the design into place as it works only in one direction and you'll need the beams there to carry the loads. But, as always with structural engineering, it's a case by case and it can save lots of money to the client.

@BrendanHasty Год назад

agree for floors it can be less efficent as you loose that benefits of two way actions, but typically it is still cheaper overally. precast design the the worst of concrete design and Steel design in one.

@Ooze27 Год назад

@@BrendanHasty Yes, it is considerable cheaper. Especially the solution with precast beams and concrete or expanded polystyrene blocks.

@@BrendanHasty I like the speed you speak at. Too many RU-vidrs speak too slowly. You might tell your listeners they can control the speed. Particularly non-native speakers of English migh use a 0.5 or 0.75 playback speed setting. Having said all of that, your microphone isn't very good. To my ears the sound is dull, muted, and kind of opaque.

@BrendanHasty Год назад

@@yekutielbenheshel354 Thanks for your feedback, I may need to upgrade my microphone system soon.

@NurbolAlpysbayev Год назад

I appreciate your videos so much 🙏 but it's not just the speed alone, it's the speed plus Australian accent that makes it really hard to understand some parts. I don't have such problems understanding American or British English 😅 again, great insightful content, please keep it up!
