TAILIEUCHUNG - Structural irregularity: The analysis of two reinforced concrete (r.c.) buildings

Structural irregularity is a crucial issue in assessing seismic vulnerability of both new and existing buildings. European technical codes provide simple criteria to define irregularities in plan and in elevation, amplifying the seismic actions and/or introducing torsional effects. | Structural irregularity The analysis of two reinforced concrete . buildings Engineering Solid Mechanics 7 2019 13-34 Contents lists available at GrowingScience Engineering Solid Mechanics homepage esm Structural irregularity The analysis of two reinforced concrete . buildings Mario Lucio Puppioa Linda Giresinia Fabio Doveria and Mauro Sassub a Department of Energy Systems Territory and Constructions Engineering University of Pisa Italy b Department of Civil Environmental Engineering and Architecture University of Cagliari Italy A R T I C L EI N F O ABSTRACT Article history Structural irregularity is a crucial issue in assessing seismic vulnerability of both new and existing Received 10 October 2018 buildings. European technical codes provide simple criteria to define irregularities in plan and in Accepted 10 December 2018 elevation amplifying the seismic actions and or introducing torsional effects. Nevertheless this Available online approach only considers geometrical irregularity. For existing buildings another source of 10 December 2018 Keywords irregularity comes from the non-uniform distribution of the material strength. In particular for Multi-storey . buildings existing reinforced concrete . structures it is possible to detect significant spread of the Material variability concrete compressive strength not only from different structural elements but also from different Diaphragm flexibility parts of the same member. In this work non-linear static analysis is performed on two case-studies Irregularity in strength of . buildings characterized by geometrical and mechanical irregularity. The resistance of each column is determined with an extensive experimental campaign with in situ and laboratory test about 600 in situ tests . The results are analyzed considering both local and global effects in terms of resistance of the single elements and of the entire buildings. In this sense shear and bending failure mechanism are .
