Generate Plate Mesh in STAAD: Part 4 - Modelling using physical objects

[@KezangLhendup-vr9iq]

Sir, first of all, thank you for the quality videos, in fact, I have learned a lot from your videos, and it will further take me to another level in the staad knowledge if you could share videos on the following topic; 1). How to model and analyze the equivalent diagonal for URM infill in staad 2). How to apply the line load of the wall to the slab that falls directly on the slab, not on the beam Thanks in advance

Hi Surojit , first of all many thanks for your wonderful and quality tutorial videos. I want PEB Warehouse complete tutorials in Physical modeler if you can sent link including limitations of physical modeler.

[@surojit_ghosh]

I planned to cover this in my video series on PEB structure, though it is not published yet. You can check more videos on this topic from here -- kzbin.info/aero/PLxLi_mmlPeirZAuVqbzXdxU46KacnGOvO

@@surojit_ghosh Many thanks Surojit, actually i have seen nearly all analytical your videos which were simply outstandingly fantabulously brilliant but i was searching for your PEB in physical modeler as i am switching over to Physical modeler and could not found. I wish to get your and only yours as your step by step explanation is extra-ordinary. Remain in touch

It has been a fact that the latest version releases of STAADPro Connect do not permit the editing of created models in the Physical Modeler mode thru the Analytical Modeler mode... Not unless the Physical Model is dropped... Hoping for your quick response of my queries below... Thanks and more power.

hallo Surojit Ghosh could u arrange a complete webinar for physical modalling.

[@surojit_ghosh]

I will try to cover this in early 2023.

For the benefit of everybody...How do you input the negative sign for the accidental torsion (i.e., ACC -0.05) in Physical Model mode?

Which is good for Designing buildings using analytical model or physical model ??

[@surojit_ghosh]

It depends on the structure. If you want to model a building structure with plate mesh (shear wall, slab or mat foundation), then it is always preferable to use physical modeler where all the connections (beam to plate, plate to plate) are internally handled, chance of error is nil. Apart from that, there are few load items (panel load, pressure load) which is more advanced in physical modeler.

any idea on mesh size

[@surojit_ghosh]

Sorry, I didn't get your query. Do want to know about the target element size? As far as I can remember, I set it to 0.25-0.5m. In physical modeler, you can control the mesh size, start with a coarser mesh, visualize and then change the target element size to make it finer. No need to remesh, as the FEM/nodes are internally generated.

[@sureshkumar-ji5kn]

What is UCS and WCS ?

[@surojit_ghosh]

It's User coordinate system and World coordinate system, a concept of defining origin and axis convention for a grid. I will create a video on this soon.
