Structure Eccentricity check Spreadsheet

Check in CSI ETABS
During analysis, ETABS automatically calculates this coordinate for each floor diaphragm. The diaphragm assignment must be present in the model. Center of rigidity and center of mass are then displayed by selecting Display –)) Show Tables –)) Analysis –)) Results –)) Structural Results –)) Centers of Mass and Rigidity –)) OK. During an earthquake, failure of structure starts at points of weakness. This weakness arises due to discontinuity in mass, stiffness and geometry of structure. The structures having the discontinuity are termed as irregular structures. In present era architects usually make the design of building with variety of shapes (irregularities) in structures to inspire their clients.
