Development of space truss systems in timber
Space trusses are a valuable structural form for architects and structural engineers due mainly to their efficiency in providing large unobstructed areas, associated with faster erection speeds and low maintenance cost. Most space trusses are made of steel and aluminium whilst a few are of timber. …

Inelastic Analysis of Reinforced Concrete Beams Subjected to Combined Axial Force, Bending and Torsion
… A unified model, which is an extension of the space truss model, is developed to solve this problem for rectangular, circular and slab sections. A nonlinear beam element which is based on the results from the space truss model is used in the analysis of grid structures on which torsion is known …

Analysis and Approximation of Viscoelastic and Thermoelastic Joint-Beam Systems
Rigidizable/Inflatable space structures have been the focus of renewed interest in recent years due to efficient packaging for transport. In this work, we examine new mathematical systems used to model small-scale joint dynamics for inflatable space truss structures. We investigate the regularity …

Damage detection in structures using frequency response function (FRF) data and finite element modelling
… FRF data applied to a simple mass spring system, space truss structure and a plate structure and effects of noise. Both numerically simulated and experimentally measured noises are investigated. Experimental FRF data were obtained for a plate structure and used for detection of physical damage and …
