解读范·德·拉恩的塑性数

Introduction to Plastic Number created by Van der Laan

塑性数是范·德·拉恩创造的、一种适合于建筑的三维量度系统,目的是使建筑的连续量和数字的不连续量结合起来,使我们可以从量上识知建筑的空间、形态。它基于我们视觉感知的误差,探究出我们对连续量的认知规律,把这一规律用塑性数表达。本文详细解读了塑性数基本比率和量度系统的推导过程,并通过维特鲁威《建筑十书》中柱距与柱径的五个不同比例和蒂莫西·哈特的雷诺兹街道联排住宅,展现塑性数在建筑中的应用。

Plastic Number is a measure-system of real three-dimensional quantity created by Van der Laan and appropriates to architecture, to make clear the meeting together of the continuous quantity of architectonic size and the discrete quantity of abstract number. Thus the quantity of space and form can be read off from the building. The laws of the plastic number are determined by the lower and upper limits of our normal ability to perceive difference in size among three-dimensional objects. The article describes how to derive the ground-ratio and the measure-systems of plastic number, and shows plastic number occur in building with five types of column thickness to intercolumniation in Vitruvius＇s ＂The Ten Books＂ and the housing project designed by Timothy R. Hart＇s.
