Rection as a Synthesis of Reciprocal and Tensegrity Structure

Abstract

There are several statements mentioning the possibilities of combining reciprocal and tensegrity structure. One of those is called reciprocal-tension (rection). This research was aimed to propose rection as a new structural system that also differs from both reciprocal and tensegrity. It defined rection structure and its characteristic, basic configuration and structural behaviour. Three simulations were conducted to test the hypothesis using dynamic relaxation method. The result showed that rection structure had the characteristics of (1) bar under bending stress, that do not touch each other, that hangs to each other reciprocally, and (2) self-equilibrated and pre-stressed system for enough rigidity. The research also concluded that the basic configurations of rection structure consist of upward fan reciprocal and positive double curvature configuration. Structural analysis also had been done on a 1:1 scale experiment and dynamic relaxation simulation.
