Half-Day Seminar on Various Fire Resistance Tests and
their Advanced Development

Organized by
Hong Kong Institute of Steel Construction
Department of Civil and Environmental Engineering, Hong Kong Polytechnic University
Supported by
Fire and Structural Division, The Hong Kong Institution of Engineers


Scope and Objectives:
Fire Safety is a big issue in infrastructure and construction buildings. In Hong Kong, we have code of practice to govern the requirements of fire safety level for different types of building. To prevent the fire spread within a building, compartments will be formed to confine the fire for a sufficient period to allow occupant evacuation and to access of fire fighters to help the victims and extinguish the fire. For those structural building elements, which are also known as the loadbearing elements, their protection under fire exposure is vital in maintaining the structural stability of the buildings under fire.


However, fire test is regarded as a large-scale destructive test, it is not practical to test every variation of a system. Therefore, in this field, an assessment approach will be adopted to involve the professional engineering judgement on the possible variations based on the fire test results. The assessment needs to rely on the experience of the assessors, and at the same time a strong professional and engineering background to support these appraisals.


In the latest researches, it is discovered that, the fire occurred inside a tunnel may generate much more severe heating condition compared to the traditional consideration of “Compartment” fire concept. In such a fire scenario, the heating condition in normal fire test (ISO heating curve) may not be adequate, especially when the high strength concrete structure is used for the lining material of tunnels. The ultra-rapid temperature rise, and high temperature will cause concrete spalling and sudden failure of the system loadbearing capability. Based on this, a heating curve (known as the RWS curve) developed by the TNO, now privatized as Efectis had been used in the fire test for tunnel lining materials.


Speaker:

HKISC is very pleased to invite Dr. L.K. Sze, Lipmann, the Technical Manager of the Research Engineering Development Facade Consultants Ltd (RED), to deliver this seminar.
