Abstract

Analyzing vibration concert of civil engineering structures due to human induced rhythmic loading is more and more critical aspect of design process of structures such as sports amphitheaters used for pop/rock concerts, floors accommodating fitness Centre and aerobic classes, and foot over bridges used as viewer walkways during social events like fireworks demonstrations. This paper is to investigate the dynamic analysis of steel floor when subjected to human rhythmic activities (Jumping) and to frame a mathematical model based on the parameters related to the properties of steel materials. The investigated structural model is taken as a steel typical floor bay of a similar steel floor like Industrial steel structure, a wide-ranging parametric study is developed concentrating on the determination of the steel floor peak accelerations because of human rhythmic activities. This paper is concerned with the dynamic study of a Steel floor slab of size 3m x 24m. The analysis is done using ANSYS. The human rhythmic activity is been lead on the slab and the Modal and Harmonic analysis are carried out. The outcomes are associated with IS 800-2007 code recommendations. A recent progress presented in this paper is a step towards more systematic and realistic using SPSS, mathematical models of group/crowd rhythmic loading that can be used to simulate more reliably dynamic response.
