Abstract
To investigate the effect of BFRP (basalt fiber) reinforced short laminated bamboo lumber (LBL) columns on axial compressive static performance, axial compression tests of twelve BFRP reinforced short LBL columns and three normal short LBL columns were conducted, and tensile tests of 13 BFRP were carried out. The test results show that the failure mode of BFRP reinforced short LBL columns was consistent with that of normal short LBL columns, buckling failure and adhesive layer failure. With the increase of BFRP cloth ratio, the bearing capacity of the columns increased. However, when the cloth ratio exceeded 2.3% (4 layers of BFRP), the average improvement of the load-bearing capacity was not obvious, and the reasonable cloth ratio was reached at 2.3%. The short LBL columns wrapped BFRP showed good compressive ductility, and the higher the cloth ratio of BFRP, the better the compressive ductility. Based on the suitable analysis of test data and referring to the relevant methods of fiber reinforced wood columns, the calculation model of axial compressive bearing capacity and stress-strain relationship model of BFRP reinforced short LBL columns were established. The comparison between theoretical calculation and experimental results verified the reliability and accuracy of the proposed bearing capacity calculation model and stress-strain model.
