Façade Panels To Impact Loads

Abstract
The performance of reinforced concrete facade components such as beams or
one-way slab panels to impact loads is examined in this paper. A building façade
is the first line of defence against external shock and impact loads. The response
of the building façade elements to such extreme loadings also influences the load
transmitted to the main structural system of the building. This significantly
affects the structural overall stability and integrity as well as the safety of the
occupants. Nonlinear numerical simulation of the impact response of reinforced
concrete beam is presented. The numerical model is developed using ANSYS/
LS-DYNA numerical code. The developed model is verified against the
experimental results of a previous study carried out at AUC. The developed
model is used to evaluate the effect of different factors such as mesh size,
elements type, material models, and contact interface elements on the accuracy
of the results. The effect of beam reinforcement, stiffness, damage, and the
supporting element on the beam capacity to sustain impact load is examined. The
effect of the studied parameters on the reaction forces transmitted to the
supporting structure is also evaluated.
