✦ Synopsis

Modern construction relies more and more on wooden structures. To minimize the costly consequences of fire, wooden beams are required to exhibit acceptable fire resistance. A combined analytical and numerical model for predicting the fire resistance of a wooden beam is presented. The model is a structural response model that takes into account the variation of the beam physical and mechanical parameters in terms of the ISO 834 temperature variation in time, to establish a partial differential equation with variable coefficients. The analysis has lead to the prediction of time to the structural failure that is necessary for safety consideration.

Carbon microspheres (CMSs) were synthesized by chemical vapor deposition in an Ar atmosphere using deoiled asphalt as carbon source. KMnO 4 aqueous solutions with different concentrations were used to oxidize the CMSs to form MnO 2 -coated CMSs (MnO 2 /CMS composites) and H 2 C 2 O 4 solution was us

The dynamic fracture response of a long beam of brittle elastic material under tensile loading is studied. If the magnitude of the applied loading is increased to a critical value, a crack is assumed to propagate across the beam cross section. In a parallel analysis to [l] the crack length and appli
