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
