THE STRUCTURAL CHARACTERISTIC OF A POLYMER COMPOSITE CELLULAR BOX BEAM IN BENDING

Pultruded glass fibre reinforced polyester composite systems are currently being considered for large scale structures such as footbridges, sign gantries over motorways and lightly trafficked road bridges. This paper discusses the experimental and numerical analyses of the short term loading performance up to failure of the cellular box beam under a four-point loading configuration. The non-linear numerical analyses utilize, as input data, the mechanical property values of coupon specimens of the material; the values are not given in the paper. It is shown that there is satisfactory agreement between the two methods of analysis. The beam displayed non-linear behaviour above a moment value of 860 kN m. The weakest part of the structure was the connection at the support end. (A)
