Unfortunately I don't think I can provide an image at this moment, but it is basically a simple 30'x30' column grid in a 6圆 matrix, and more speculative at this point. It provides a way to get quick structural analysis feedback on a structure at. I am not sure if this can be achieved using the natural vibrations component or not, or if there are other tools that can achieve this calculation in Karamba. Karamaba3d is a structural analysis tool which is embedded within Grasshopper. So, to summarize - based on an input slab, we would like to calculate the mips produced on a floor-slab based on pedestrian footfall in steps/minute, then use this data to determine specific slab thicknesses.

Karamba3D is being developed by Clemens Preisinger in cooperation with Bollinger und Grohmann ZTGmbH in Vienna.

It lets you analyze the response of 3-dimensional beam and shell structures under arbitrary loads. I know there is a 'natural vibrations' component that takes in a model and outputs frequency in Hz, however I am a bit confused on some of these other inputs and outputs, such as 'NModes' for example.Įssentially, what we are trying to do is take a floor slab and:ġ) Assign zones, such as corridors to the slab (presumably subdivided meshes)Ģ) Give that slab/zones a walking criteria (footfall in steps/minute) - corridors have a greater walking criteria for instanceģ) Output the Mips (micro-inches per second) value for particular affected areas/zones on the slab - can be represented in some color range for the respective values accross the mesh.Ĥ) Assign slab thickness based on optimized zones of vibration Karamba3D is an interactive, parametric finite element program. I am wondering if it is possible to calculate footfall induced vibration across a floor plate using Karamba.
