Dynamic Analysis of Cylindrical Steel Silo Structure with the Effect of Shear Wall

Civil

Shells of various shapes were investigated such as elliptical hemispherical, conical and cylindrical shells. These structures are mostly failing by bucking under external pressure. Cylindrical steel silos are big lean structures used for storing materials like cement, grains, fly ash, carbon black, coal saw dust etc. They are special structures subjected to many different unconventional loading conditions, ranging from few tones to hundreds to thousands of tones which results in unusual failure modes. In this work considered the steel silo structure as per literature data and apply the different shear wall curvature. The method has been applying in this work is response spectrum analysis, which are robust dynamic analysis tool in STAAD.Pro. The present work investigates and compared the lateral analysis of steel silo structure with different model types and provide the best as compared to specified structure type and literature basic structure. From in this work it has been observed that the steel silo structure with shear wall-A type are more useful than the others. The deformation structure and stress in plate are obtained to be critical more in literature, shear wall-B, shear wall-C and shear wall-D as compared to shear wall-A. The work is also representing the behaviour of steel silo structure with varying the plate thickness and kept constant the other silo parameters.
