On the use of systems for tests on stainless steel members and frames aimed at interoperability

Abstract

An experimental development of systems for tests on stainless steel members and frames aimed at providing interoperability is presented. In the context of the project PINOX, tests on stainless steel members and frames have been conducted and provided with traditional measurement techniques. In addition, systems aimed at providing interoperable data to other platforms were added, namely: i) Measurement systems for developing low‐cost sensor‐to‐cloud applications as well as Digital Image Correlation, ii) Displacement measurement for developing virtual and augmented reality applications and iii) terrestrial laser scan (TLS) measurements for developing IFC models for design and analysis across BIM platforms. In the first case, the interest is related to developing interoperable, low‐cost, cloud‐based, open‐source tools in the context of structural engineering laboratories. In the second case, the interest is the use of virtual (VR) and augmented reality (AR) as alternative media when deploying tests on structural elements. The third case is explored for obtaining measurements and tracking initial imperfections on real structures, with great interest for in situ applications. Conclusions about educational, technological and practical potential of these applications are pointed out.

Structural behaviour of stainless steel frames. Safety against accidental seismic actions

“…In addition, several points of the frames were monitored during the tests and their movements were recorded using a Lidar system (see Figure 3.2). Preliminary results corresponding to this analysis are available in (Chacón et al 2021). EN 1993EN -1-1 (2005, the equivalent sway imperfection to include in the frame analysis can be estimated through the expression given in clause §5.3.2(3).…”
