Abstract
The nature of gravitational forces exerted by topological defects on surrou nding matter in the frame of Brans-Dicke theory of gravity (BD) is investig ated. Comparison is made with the corresponding cases in General Relativity (GR). The role of the scalar field as a weakener agent of the strength of gravitational forces due to pressure terms is discussed.
