Earthquakes often induce non-linear response in structures. However, most practical seismic design continues to be based on linear analysis. The objective of this research is to develop a software program for Earthquake analysis of planar frames according to the provisions given by Ethiopian Building Code Standard (EBCS-8, 1995) and compare the results from the developed program with other sources. The most commonly used methods for dynamic analysis of structures subjected to earthquake loads are modal and spectral analysis. Response spectral analysis given by the provision of EBCS-8, 1995 is used for developing this computer program. In this thesis, an overview of various dynamic analysis procedures is presented with a detailed description for response-spectrum analysis, which is used to develop the computer program. Conclusions are drawn concerning the reliability of the responses given by the developed program. Recommendations for the use of the program are also provided.en-USBuilding FramesDyanamic AnalysisThesis
