Abstract
The cladding
system of a building is crucial for protecting people and equipment against
external explosions. Both experimental
and numerical investigations are carried out in order to evaluate the
resistance of precast concrete cladding wall panels against man-made attacks. The cladding system under investigation is a
precast concrete wall panel for using in police station facilities that
particularly need to be protected against man-made or subversive attacks. A total of three precast concrete cladding
wall panels are studied. The panels are
3500 mm long and 1500 mm wide; and one is 150 mm thick while the other two are
200 mm thick. The longitudinal
reinforcement consists of a single layer of reinforcement bars located in the
middle of the cross section. The blast
demand is due to the detonation of 3.5 and 5.5 kg of TNTeq, and the numerical
simulations are carried out using the finite element software LS-Dyna©. Details of the experimental and numerical
investigations are shown, and a discussion on the obtained results is provided.
