Abstract

This study introduces a novel design technique for the rib pattern of slab structure using visual programming. It aims to investigate the possibility and capability of visual programming for a rib pattern design in the grasshopper environment. For this purpose, Nervis's approach is revisited and reconstructed in the digital environment. The NURBS(Non-Uniform Rational B-spline) definition is introduced to represent the slab geometry and redefine the principal stress line with kinks for smoothing purposes. The response of the slab is evaluated by using OpenSees via the plug-in Alpaca4d. The entire process is utilized with the generic components of the grasshopper and two specific plug-ins. From numerical results, the proposed design process efficiently produces rib patterns of the slab and can be used in arbitrary slab shapes with openings.
