Construction Technology 2 - Essay Example Because the fire curves are modelled on the basis of design fires, the analysis becomes vulnerable to the difference between design fire parameters and the real fire situations that may occur. Furthermore, varying conditions and the global proliferation of standards for fire tests make it imperative that an approximate approach to different situations/standards, for structures (at sea and on land) be adopted. This work aims to analyse fire curves in terms of their vital components/features, simultaneously considering the critical levels at which these vital variables of the standard curves experience a change, with the associated consequences of such, regarding the effectiveness of fire curves at carrying out their function of fire resistance determination. A further look will be taken at the applicability of these curves at sea, with analysis involving a look at the means and extent to which these applications vary, in the approach associated with them. The level of fire resistance in structures (onshore) is generally assessed or analysed by the use of engineering fire design curves. Different types of fire curves and standards are adopted in various parts of the world. Different assumptions are also associated with these different curves. Technically speaking, fire curves are applied to determine the fire resistance rating of passive fire protection systems. This rating is a measure of the time over which a passive fire protection system can resist or withstand a standard fire protection test. Some of the most commonly used standard fire curves include the ISO-834 (BS 476 or DIN 4102), which are relevant to cellulosic structures. There are also the ASTM E119 and UL 1709(or Eurocode 1), applicable to hydrocarbon situations. Engineering design practice generally uses these curves in the context of design fire temperatures, which attempt to
