Abstract

In the last two decades there has been increase in air traffic along with the density of tall
buildings. This has increased the chances of their collision, which may be accidental or deliberate. Therefore
structures situated near airports and the buildings of high importance must be designed taking this into
consideration. Also, the damage assessment of the existing structures needs to be performed against such
unpredictable events.
In this research, numerical simulations were carried out using ABAQUS/ Explicit software to study the
response of a fictitious rectangular steel framed building against collision of Boeing 767-400 ER. The nature
of problem is highly complex as a matter of fact that the two interacting bodies demonstrate different
mechanical behaviour and damage response due to their distinct stiffness and material properties. Johnson
Cooks model was incorporated to simulate the behaviour of steel, which takes into account high strain rate
and increased temperature due to friction between colliding bodies. For concrete, concrete damage plasticity
(CDP) model was used, which follows tensile cracking and compressive crushing failure mechanism.
Different locations of strike of aircraft having weight 204 tonnes and speed 104 m/s have been studied. Top
corner of the building was found to be most critical point.
