A Collaborative Workflow to Automate the Design, Analysis, and Construction of Integrally-Attached Timber Plate Structures

Yves Weinand, Petras Vestartas, Nicolas Henry Pierre Louis Rogeau, Aryan Rezaei Rad, Pierre Latteur

This paper introduces a computational framework that fosters collaboration between architects, engineers, and contractors by bridging the gap between architectural design, structural analysis, and digital construction. The present research is oriented towa ...

In the architecture, engineering and construction (AEC) sector, the use of point cloud data is not a novelty. Usually employed to retrieve data for inspecting construction sites or retrofitting pre-existing buildings, sensors like LiDAR cameras have been k ...

Association for Computer-Aided Architectural Design Research in Asia (CAADRIA)2022

Before the twentieth century and concrete modernity, it was stone that embodied the “well built”. Could sustainable wood one day replace concrete as the archetypal material? Will it find a place on the scale of values that gives archi- tecture its referenc ...

EPFL PRESS2022

The immediate application of research discoveries requires a global and exact understanding of the structure under consideration. To gain insight into the complex behavior of structures, numerical simulations are carried out in parallel to physical experim ...

Robotically-Fabricated Nexorades from Whole Timber

Yves Weinand, Petras Vestartas, Aryan Rezaei Rad

This paper introduces the conceptual design of sustainable timber structures using raw wood. It pre-sents a workflow for systematically generating Nexorades using a tiling method for multi-valence quad subdivided surfaces. The system is designed based on a ...

2021

Currently, the Swiss timber industry in mountain areas largely exports unprocessed lumber and imports finished timber products due to the lack of digital tools. By using new digital design-to-production workflows, it is possible to investigate new building ...

A framework to automate the design of digitally-fabricated timber plate structures

Yves Weinand, Petras Vestartas, Nicolas Henry Pierre Louis Rogeau, Aryan Rezaei Rad, Henry V. Burton

The current study uses knowledge from digital architecture, computer science, engineering informatics, and structural engineering to formulate an algorithmic framework for integrated Computer-Aided Design (CAD) and Computer-Aided Engineering (CAE) of Integ ...

Joinery Solver for Whole Timber Structures

Yves Weinand, Petras Vestartas

This paper presents a digital joinery generation method for whole-timber structures using wood-wood connections. The research is based on a collaboration with a local timber company located in a mountain area [1]. In this context, there is a need to explor ...

Laser Scanning with Industrial Robot Arm for Raw-wood Fabrication

Yves Weinand, Petras Vestartas

This paper presents an integrated raw-wood fabrication workflow using an industrial robot arm and a laser scanner. The research is situated in a Swiss mountain forestry context where timber in its natural form could be applied locally without relying on la ...

Segmented Spiral using Inter-Connected Timber Elements

Yves Weinand, Petras Vestartas, Aryan Rezaei Rad, Anh Chi Nguyen, Martin Thomas Nakad, Loïc Henri Pelletier

This paper describes the design, fabrication, and construction process of a scenography structure representing a five-meter height spiral made out of 3-ply crosslaminated panels. The structure includes 29 timber boxes. Typical through-tenon wood-wood joi ...
