| dc.description.abstract | Fundamental natural period of vibration T of the building is an important parameter for evaluation of seismic base shear. Empirical equations given in current building codes like ESEN 1998-1:2015, EC8 (EN 1998-1: 2004), Applied Technological Council of 1978 (ATC3-06, 1978), American Society of Civil Engineers (ASCE 7: 2010), Indian seismic code (IS 1893:2002) and other current building codes for the calculation of the fundamental period of a framed structure, primarily as a function of height. The intent of this study is to understand the dynamic behaviors of buildings with different configurations under seismic loads. It is a well-known fact that the first fundamental period is directly affected by not only the framing type but also the number of floors and the in-plane aspect ratio, regularity, story stiffness, story height and building masses. Therefore, the number of floors and the in-plane aspect ratio, regularity, story stiffness, and story height are used in the parametric studies by selecting 3D actual buildings. For this purpose, eleven sets of floor levels, 3, 4, 5, 6, 7, 8, 9, 10, 11, 13 and 14 stories or 9m-45m height buildings were studied in evaluating the fundamental period. In order to study the influence of other parameters such as number and width of bays, height and number of story, irregularity and story stiffness were investigated in this study. To investigate these parameters, 39 actual reinforced concrete buildings were modeled and analyzed by Modal analysis and Rayleigh‟s method using computer software ETABS 2015. Periods of building frames were tabulated and plotted against the pre-listed parameters and finally conclusions were drawn from the results obtained from analysis. | en_US |
