| Abstract | ||
| In this study, the Basalt fibers from basalt rocks are used to strengthen openings in deep beams where this fiber is an environmentally friendly material that doesn’t produce any toxic reactions with air or water, and its surface is anti-explosion. Also, it doesn’t produce chemical reactions that may damage the environment or human health, when it contacts other chemicals, it is safe for use in industry and has no pollution, and the effect of strengthening deep beams with openings vertically by using these basalt fiber sheets is studied. A practical program has been developed to study the behavior of deep beams strengthened with basalt fiber-reinforced polymer (BFRP) sheets. The practical program consists of 6 beams designed as American code, with various types of openings. The results of the tested sheets and results of beams such as deflection, cracking load, crack propagation, ultimate load, and failure character, are recorded. Also, nonlinear analysis and mathematical equations are used in this study. This research can achieve that the basalt fiber sheets could affect slightly on the behavior of the deep beam with openings in cracking loads, deflections, stiffness, energy capacities, and ultimate loads | ||
