EFFECT OF NON-STRUCTURAL ELEMENTS ON STRUCTURE AND DAMAGE ASSESSMENT

Abstract

The facades are usually considered as architectural elements and are not accounted for in the structural design, even though they could significantly influence the overall performance of the structure. This study aims to examine the impact of NSE (Sliding and fixed Façade) on the general structural behavior and evaluate the resulting damage. A 2D, 5-storey, 3 Bay MRF was modelled on OPENSEES, and the behaviour of the façade was modelled through a non-linear spring by using a Pinching4 material. Static and dynamic non-linear analyses were conducted on, with and without façade and the results were compared. Then, damage estimation was done by comparing the results with fragility curves. The results showed that the presence of Façade increased stiffness of the building and thus, decreased drifts and time periods. From damage estimation, we can also state that sliding façade behaves good as compared to fixed façade and is prone to less damage.
