Abstract:

Detection of structural deterioration in hybrid building constructions is considered in the present work. The constructions belong to semi-rigid or ‘bending-active’ systems. They consist of fiberglass rods, struts, cables and membrane. Hybrid constructions have found use in roofs and facades of permanent buildings and for temporary canopies as well.Detection of structural deterioration includes developing machine learning models in form of artificial neural networks. Appropriate structures of the networks and parameters of the hybrid buildings are given for two types of deterioration cases: material aging and slackening, as well as the membrane tearing.Semi-supervised learning strategy is used for training the networks. Discrepancy between the vector of structural parameters and the resultant vector, generated by the network, is considered the indicator for subsuming the hybrid construction under normal or anomalous (deteriorated) classes.The work contributes to implementation of machine learning techniques for research and development of hybrid building constructions. It facilitates automated structural health monitoring of complex modern buildings.

I. Introduction

Hybrid constructions consist of dissimilar structural elements, such as stiff rods and struts, as well as flexible membrane and cables which are assembled for optimal fitting their primary functions [1]. The rods and the struts bear non-uniform and point loads, thus mitigating structural deformations. High-strength cables are effective for buildings with large column spacing. Polymer membrane forms lightweight and architecturally impressive shell. Hybrid constructions have found use in roofs and facades of permanent buildings, such as railway stations, airports, exhibition halls and stadiums [2], as well as in temporary canopies for recreation areas, points of retail and construction sites.
