New technique used for strengthening jack arch slabs
The use of fiber-reinforced polymer rope (FRPR) increases the seismic performance of unreinforced clay brick masonry slabs and the flexural strength of jack arch slabs or roofs. This study represents an attempt to explore the capability of using FRPR for strengthening the jack arch slabs. For this purpose, ten jack arch slab specimens were built and tested under three-point load conditions. The main parameters investigated were the brick type (solid and perforated), camber (0 and 30 mm), span width (700, 730, and 950 mm), strengthening scheme on the behavior of the jack arch slab of FRPR, and number of FRPR points (i.e., number of FRPR strengthening points used for each span). The results show that using perforated brick types enhanced the ultimate carrying capacity of the slabs compared with the solid type. With increasing camber, it was observed that the ultimate capacity of the slabs also increased by the range of 13–11% for the solid and perforated specimens, respectively. Furthermore, increasing the span width resulted in a 69% reduction in maximum deflection. FRPR can be utilized for strengthening masonry buildings and historical structures.
