Lego architecture: Research on a temporary building design method for post-disaster emergency

Disasters are becoming the norm in this world, which also poses challenges to architects. Many needs to build temporary buildings may occur at the same time randomly around all over the world. Constructing an efficient and economical solution is the motivation of this research. Through a comprehensive review of all past related researches and architectural practices, "convenience" and "recyclability" have been identified as two important features of temporary buildings in the post-pandemic era. In this article, we carry on a novel research of discrete architecture. Based on the design paradigm of discrete architecture, this research uses the three main components of S/U/P to develop a Lego Architecture design method by combining with the Grasshopper plug-in under the Rhino platform to write a program that automatically generates the target plan. Then, a typical design scheme for physical construction verification and structural optimization is selected to ensure landing and safety. Originating from the thinking of productization, this research attempts to package the design methods and related knowledge into a systematic solution, relying on an open construction system framework to achieve a rapid, simple and safe construction of temporary buildings after disasters.
