Abstract
As the living standards of building residents continue to improve, along with safety and economic considerations, engineers are placing greater emphasis on the comfort of inhabitants. One significant human-made crisis that threatens society is noise pollution. Over the past century, factors such as population growth and the proliferation of high-rise constructions have posed challenges to mental health. Unwanted noise can emanate from both inside and outside of buildings. One of the main sources of indoor noise is the impact sound caused by residents walking on building floors. Currently, this type of sound is managed only through non-structural measures, as outlined in Volume 18 of the Iranian National Building Code. Unfortunately, it lacks coverage in the structural analysis and design of building components. From a structural perspective, Volume 10 of the Iranian National Building Code inadequately addresses acoustic limitations. It presents only a table specifying a minimum frequency of 5 Hz for residential floors. This paper examines the effect of foot-induced vibrations in buildings with steel deck floors, utilizing ETABS software in conjunction with the AISC code. Despite the lack of comprehensive acoustic regulations, the results reveal that even when complying with the design criteria established in Volume 10 of the Iranian National Building Code, the vibrational comfort of residents in apartments with steel deck floors may not be adequately assured.
