Shaking Table Tests of Seismic Performances of a Masonry Structure Retrofitted with CFRP Laminates
摘要
Abstract
To study the seismic performance of masonry structures retrofitted with CFRP laminates, shaking table tests a 1/4 scaled two-story and two-bay masonry structure involving constructional columns which was strengthened by CFRP laminates were carried out under the excitations of two natural earthquake records and another artificial one. The results show that cracks were observed firstly in the mortar between bricks of the test model and extended gradually with the increase of the seismic input; however, the CFRP laminates limited the development of the cracks effectively. The dynamic magnification factor of the second story of the test model is about twice of the first story. When the peak value of the input acceleration history curve increased to 1. 4g, the maximum story drift ratio augmented to 1/42, and there is relatively large difference between horizontal displacements of two sides of the test model, which shows that the test model experienced obvious torsion, but no severe damage was observed. The study in this paper reveals that the masonry structures retrofitted with CFRP laminates have large capacity of seismic-resisting and deformation.关键词
