Volumetric intersections: Modularization approaches for freeform prefab concrete construction

Automation in the Prefab and Modular Construction Industry

The construction industry at-large is dominated by numerous small and specialized sub-contractors who typically are not technologically advanced enough to embrace automation. The sector that represents factory built housing (the modular, prefab, panelized, precast, etc.) is an exception. Since the products are built in factories, the principles of mass production and mass customization that are...

Real-Time Volumetric Intersections of Deforming Objects

We present a new algorithm for the computation of volumetric intersections of geometrically complex objects, which can be used for the efficient detection of collisions. Our approach requires neither expensive setup nor sophisticated spatial data structures and is specifically suitable for handling deformable objects with arbitrarily shaped, closed surfaces. The algorithm employs a Layered Dept...

Efficient Voronoi diagram construction for planar freeform spiral curves

We present a real-time algorithm for computing the Voronoi diagram of planar freeform piecewise-spiral curves. The efficiency and robustness of our algorithm is based on a simple topological structure of Voronoi cells for spirals. Using a Möbius transformation, we provide an efficient search for maximal disks. The correct topology of Voronoi diagram is computed by sampling maximal disks systema...

Concrete Shear Wall Construction

Buildings with cast-in-situ reinforced concrete shear walls are widespread in many earthquake-prone countries and regions, such as Canada, Chile, Romania, Turkey, Colombia, the republics of the former Soviet Union, etc. This type of construction has been practiced since the 960s in urban regions for mediumto high-rise buildings (4 to 35 stories high). Shear wall buildings are usually regular in...
