基于ATENA的梁侧锚固钢板加固梁中纵横向滑移数值模拟
Numerical simulation of longitudinal and transverse slips in bolted-side plated RC beams based on ATENA
摘要
Abstract
Reinforced concrete (RC) beams strengthened with bolted steel plates on their vertical faces are known as bolted side-plated (BSP) beams. The performance of BSP beams are controlled by the partial interaction due to the longitudinal and transverse slips on the steel-concrete interface caused by the shear deformation of the bolt connection under the shear force transferred from the RC beam to the bolted steel plates. A nonlinear finite element analysis (NLFEA) using the computer software ATENA, which was validated by the outcomes of a previous experimental study, was conducted to investigate the behaviour of BSP beams with different beam geometries and under various loading conditions. The effects of loading arrangements, the stiffnesss of RC beams, steel plates and bolt connections were further investigated by a parametric study. The results show that linear bolt shear force-slip relation and force equilibrium are found in both the longitudinal and transverse shear transfers and slips. The magnitudes of the shear transfers are proportional to those of the external loads, but their distribution profiles are controlled by the loading type in stead of the magnitudes of loads.关键词
