Limitations in Simplified Approach in Assessing Performance of Façade under Blast Pressures
Abstract: The main function of
building facades, which often consists of glazing windows, is to provide
protection to the occupants and contents of the building from external hazards.
In a blast event, the facade component of a building may become the weakest
link of the structure, whereby its breach may lead to blast pressure ingress
and hazardous projectiles into a structure. This paper reports part of a study
to establish the performance of glass windows under blast pressures. Two
modelling techniques were used to simulate the response of a façade panel. They
are the Single Degree of Freedom (SDOF) modelling technique and the Finite
Element (FE) modelling technique. Although the SDOF approach can be used with a
reasonable degree of accuracy, the limitations of its basic assumption lead to
loss of details in the idealisation process. This paper presents an attempt to
establish performance indices of a façade panel, and to identify the
discrepancies between simplified approach and the detailed numerical modelling
approach analysis.
