Response of A Steel-concrete Composite Building Vis-a-vis An R.C.C. Building Under Seismic Forces
D. R. Panchal, Lecturer, Applied Mechanics Department, Faculty of Technology and Engineering, The M. S. University of Baroda, Vadodara, & Dr. S. C. Patodi, Professor, Civil Engineering Dept., Parul Institute of Engineering & Technology, Limda, Vadodara.
Unlike static forces, amplitude, direction and location of dynamic forces, especially due to earthquake, vary significantly with time causing considerable inertia effects on building. Behavior of the building under dynamic forces depends upon the dynamic characteristic of the building which is controlled by both their mass and stiffness properties. In the present study, for evaluating the seismic performance of a typical B+G+9 multi-storey building, steel-concrete composite and R.C.C. options are considered. Two popular methods of seismic analysis i.e. Equivalent Static Method of Analysis and Linear Dynamic Response Spectrum Method of Analysis are used. For modeling, the composite and R.C.C. structures STAAD.Pro, V8i software is used and the results of the analysis are compared; composite structure is found to be more economical.
