Finite Element 3D Modeling of Reinforced Concrete Structures Subject to Earthquake Loading

Abstract

Shaking table experiments of relatively large-scale specimens have become crucial in deepening our understanding of how reinforced concrete structures respond to seismic movements When these dynamic tests are modeled numerically they can provide a wealth of information to engineers and designers at a more cost-effective rate than laboratory type testing Many commercial software programs can perform three-dimensional structural analysis; however they have limitations in their analytical functions and capabilities to model complex composite materials such as reinforced concrete This project will develop a 3D finite-element model of a ? scaled three-story reinforced concrete building tested under dynamic conditions applied through a triaxial shaking table housed at the National Center for Research on Earthquake Engineering located in Tainan The building specimen is representative of many mid-rise buildings in Taiwan that were damaged during earthquakes such as the 1999 Chi-Chi earthquake and the 2016 Meinong earthquake The finite-element analysis will be done using the advanced computer software ABAQUS/Standard and will take advantage of the concrete damaged plasticity material model Also solid elements will be used to model the concrete and truss elements to model the steel rebars Results of a linear dynamic analysis showed that acceleration and displacement time-history data compared well with experimental results thereby indicating that the ABAQUS concrete damaged plasticity model can successfully be used to model reinforced concrete to predict the dynamic behavior of structures
