Building with billboard, time history analysis, structural response, modal analysisAbstract
Installation of billboards on various structures adjacent to busy roads has become common practice as they provide high economic to the local municipal corporation or private business organisations. Till recent, design of billboards and its installation on a structure was of less importance, but recent large wind cyclones had led to the collapse of billboards and structural cracks. This incident has raised doubts in structural engineering community for the resistance of buildings with billboards during earthquakes. In this study, an existing building with the recent installation of a billboard has considered, and dynamic analysis is carried out for three different ground motions viz. El Centro earthquake, Loma Prieta earthquake and Uttarkashi earthquake for understanding the change in its behaviour with and without billboard. The structure has shown an increment of response due to the installation of a billboard during earthquakes.
