Evaluation of Seismic Response Modification Factor of Multistory Buildings DesignedAccording to Egyptian Code
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 1
Abstract
This study is mainly concerned with the calculation of the values of response modification factor at failure for idealized reinforced concrete moment resisting multistory frame systems designed according to the Egyptian code of loads ECP-201 (2012). Parametric studies are carried out for RC moment resisting frame with 3, 6 and 9 stories that are modelled in three-dimensions as residential buildings with different configurations and variable parameters. SAP2000 software is used to model and analyze these systems using three-dimensional nonlinear static pushover analysis considering material and geometrical nonlinearity. The buildings are studied under the effect of several parameters such as single or multi-bay frame, number of stories, seismic zone intensity and type of spectrum according to Egyptian code. Their effect on pushover curve, R-factor and its components are analyzed. Comparisons between the results show the difference of some values and the indifference of others values including R-factor values.
