Building Design & Analysis: Load Paths for Lateral Loads and Bracing Design

Рет қаралды 29,650

Күн бұрын

This video discusses how to carry out a load path analysis / load run down on lateral loads in a multi-storey building. A bracing layout is developed for the structure. A real world structure is discussed to show the practical application of the work. A simple model shows the behaviour of tension-only bracing and lateral deflections. From these analyses the bracing could be designed quite easily.

These videos are really good and well structured. Do you plan to continue with this type of content?

You can have a look here and at the channel "Richard Walls" for various structural engineering videos.

Thankyou thankyou so much for making this whole series. I had been searching for such an explaination for quite some time. Really thankyouuu!

I’m an environment artist for self study and trying to understand how to sketch better but this was really helpful. Thank you 🙏

Hi Professor Walls, thank you very much for the great videos. In 14min,09sec, how would you determine the direction of R1. In the previous model, wasn't it in the opposite direction?

@firesun 3 жыл бұрын

Dear Saman You are correct - R1 was in the opposite direction in the previous model. If you take sum of forces between the two models at that point the result will be zero as they must cancel - hence, must always be in opposite directions. In the first model R1 shows the support provided by the floor bracing. In the second model (at 14:09) R1 shows the load applied by the vertical braced bay. Hope this helps. Kind regards Richard

Where did you get that model kit?

@firesun 3 ай бұрын

The plastic kit comes from a toy shop. It is a kit for kids consisiing of balls with holes and plastic sticks. Just made it up and adding bracing from string.

This building has been structured in which software?

@samiraljoburi1198 3 жыл бұрын

l need the name of the program too.

The 3D model was done in Tekla. The analysis was done using Prokon Frame. Most of the diagrams have been done in Powerpoint.

Isn't the building still unstable in the transverse direction? I'm just starting out on my structural engineering and design journey working for a scaffolding company..... this means that ALL of our work is basically designing braced frames. My gut instinct here is that the bracing depicted doesn't sufficiently account for transverse lateral load? Assuming (as you outline) that the joints are all 'true pins'? As a rule of thumb in the Australian Scaffold industry, is to brace on both the Front and Side elevations while Plan bracing is only used for particular arrangements such as resisting twist in parallel 'ladder girders' or spurred/cantilevered bays.

You are correct. This structure is only braced in one direction. If we added bracing in the other it would make the illustrations and video confusing. However, you would simply follow the same steps for loads perpendicular to those shown.
