Abstract: This paper presents a study for optimizing the blank parameters of rolled threaded auto components. The experiments have been designed to optimize the outer diameter of thread M8×1.25 6g by Taguchi Method. The outer diameter of the external thread is dependent on the parameters like surface roughness, out of roundness and material’s properties such as tensile strength etc. An orthogonal array L9 (OA), signal-to-noise(S/N) ratio and analysis of variance (ANOVA) were employed to investigate the range of outer diameter of a screw thread. The optimum combination of surface roughness, out of roundness and tensile strengthof materials has been shown in this paper

Abstract: The emerging concept of performance based design relies on a careful consideration of all aspects involved in structural analysis. One of these aspects of structural analysis involves soil-structure interaction (SSI). Current research has focussed on analysing the beneficial and sometimes detrimental effects of SSI to the performance of isolated structures. However, real structures are built in clusters (city blocks) and the seismic performance of one building influences the performance of surrounding buildings. To improve understanding of this effect, a number of building clusters with varying parameters are taken and their peak responses with varying frequencies have been studied in this paper. These results show that cluster effect is significant and the resulting response amplification in certain buildings of the cluster may justify structural retrofitting in existing buildings.
