Abstract
Pultruded glass fibre-reinforced polymer (GFRP) composites have favourable mechanical and structural properties that makes it a promising structural material for building floor construction. Recently, a new GFRP floor system has been developed in Monash University. The floor system is a web-flange sandwich panel with pultruded GFRP box profiles incorporated between two pultruded GFRP flat panels. However, due to the lightweight and lightly-damped nature of GFRP, this floor system could be susceptible to excessive vibrations due to human dynamic loadings, leading to problems with vibration serviceability. In turn, monitoring structure dynamic performance is important in GFRP floor systems. Conventionally, computer models of floor structures were used along with experimental data to assess structural performance. To this, an in-house finite element (FE) model is developed to assess the dynamic performance of GFRP sandwich panel floors. In this FE model, GFRP sandwich panels were modelled as equivalent plate elements together with Timoshenko beam elements to form a typical slab-beam floor configuration. This paper presents the development and validation of the in-house FE model. The validation is performed using experimental data of a laboratory GFRP sandwich panel footbridge. The boundary conditions of the footbridge (beams and end supports) provide good validation basis for an equivalent one-way spanning GFRP floor system. By validating the FE model, reliable numerical predictions of modal properties, and structural responses (e.g. deflections and accelerations) can be achieved for vibration performance assessment of GFRP sandwich panel floors.
