Why Performance Based Design Achieves Structural Efficiency

performance-based design of structures overcomes some of the shortcomings of following the prescriptive approach when undertaking the traditional codified design. The performance-based design allows you to find the optimal solution that meets serviceability, structural capacity and robustness while still ensuring your design is efficient and sustainable. Performance-based design of tall buildings is often something that is overlooked in structural design, because of Performance-based seismic design, however, you can achieve efficient design

My name is Brendan, and I am a structural engineer with over 15 years of experience in Australia. I have a wide variety of projects, from very small to some of the biggest in the southern hemisphere. I have a passion for good structural design and teaching/mentoring.

This channel is to share my passion for engineering and provide entertaining short clips on:
- tips for young engineers on progressing their careers
- anyone needing a refresher on any design element
- design approaches
- Review past engineering failures to improve structural knowledge

Sir Outstanding job🙌🏼🙌🏼🙌🏼
You are a real genius!

Why don’t you open a Virtual design training center/institute where we can register and practically learn from you, using a software you recommend.
Project based course will do.

Greetings Froom colombia south América, presstresed and steel design. Please. Skyscrapers, fazlhur khan son. Great channel

[TonioCartonio]

Last year in university I took a course about seismic design, where the professor taught PBD and seismic isolation (applied on RC structures). My first reaction was something like "wow, the idea is amazing", and as the course progressed I felt like i was understanding in a better way how the building works. Just wanted to share this, have a nice day Brendan

[fillbertnjoko]

Is pushover analysis often used after designing a structure?

[Mark-cyow]

Hi Brendan good job with these video very informative WSP is lucky to have you on the team

[fajarali]

What software i learn? I doing Bechlors civil engineering( general). So that i can get a job in Australia when come to Australia as fresh engineer.... Kindly what software do civil engineers use... Kindly make a video or reply in comments

[Schmitty]

Hey Brandon love the channel and by far one of your best videos. Design build and pba are big methods now! I study at cal poly Pomona for civil engineering and would love to chat!

I am a structural engineer here in Australia, have 20 years of experience. I have been using advanced non linear analysis for over 15 years, for seismic actions and wind loading. I’ve been developing new methods of engineering precast concrete structures using vertical post tensioning. We have undertaken physical full scale testing at Swinburne university on this new innovative system.
I’ve used non linear pushover analysis for structures here for 12 years on very tall towers to sway frame retail structures. It is very true that PBD produces structural optimisation, even under wind loads.
As a professional engineer the attacks I have been subject to during peer reviews by the biggest consultants in this country has been extraordinary, and depressing. The more advanced you are as an engineer, the more the code compliance specialists undermine the profession and innovation.
I am quite impressed and happy you have produced this video. Reach out if you want to discuss.

Hei Brendan,
I am a student in structual engineering. I am not understanding the concept when everything is included. I have many question:
- Can you make a step by step videosfrom start to finish how multy storey building are built?
Do you start first by structual analysing the whole building frame, then design it with the national or international codes?
How are modern walls built, with steel and glass or aluminium or wood?
Masonry structures from the 1900 hundred are symmetric and have good aesthetic form into it. What kind of materials did they use, brick or stonework unreinforced masonry, wont it collapse during earthquakes

[oslekcom]

I ran a 40 story building in LA and took me 3 days to run for only 7 sets of ground motions now you are required to use 11 sets of ground motion wow

[igorbt]

Do you have any comment about the Millennium Tower in San Francisco that sustain significant tilting. Do you think that still could be saved o should be demolished before a suddenyi catastrophic event happen?

[lukew]

Hi Brendan, appreciate your videos. Regarding structural design, have you ever had to deal with heritage listed components. If so what are the approaches you would use to incorporate heritage in your design. For example, using sandstone for bridge columns.

Moreover, If possible could you make a video doing resume critiques and any advice on gaining a structural engineering internship.

Push-over method is not suitable for high rise buildings or irregular structure, what’s more, it’s only suitable for building which dynamic performance is governed by its 1st vibration mode.

[mrp]

Hej Brandon and thanks for the video! Is this the push over analysis that you analyze here?

[BoZhaoengineering]

Solid on this topic! Thank you for the video, Mr. Brendan. I almost use Response spectrum analysis, RSA, for all scenarios. And it is the method, recommended by Euro Code 8 for every type of structure. Some literature tells us how it works. But the left is how to combine the action for the structures as 'equivalent loads' for the accidental category in load and resistance factor design. The FEM software I use offers the combination method for each significant direction affecting the structures.

[manasavuibaubatiwale]

Awesome video mate 💯 Just two questions: 1. "How do you manage your time between YouTube, Work and family?"... and 2. "Could you do a video series on designing a simple structure according to AS/NZS codes?" Cheers 😊

[PeterRanieriII]

Very interesting topic as always from you Brendan! I would just warn engineers trying to design buildings into the plastic deformation zone is not something the department of buildings here in NYC likes. Just make sure you always are checking your local codes for what would be acceptable because at the end of the day we have to comply with the code...even if it's behind the times! The last thing you want is an audit of your building and they make you completely redesign because you are too smart for the code enforcers

[ladiidoodi]

Hey may I ask if you can do a video on how to apply PBD using design softwares, much better of you do it in ETABS . Thank you!

[Karimclean]

Hey brendan! I have a question/video suggestion. What type of entry level structural engineering interview/technical questions do firms ask when hiring new engineers?

[DeepakKrishna]

Solid info, performance based design is not given much attention in universities still. Keep going.
