Because polymer-composite reinforcements are a new material in construction, the possibilities of their use load-bearing structures, including concrete beams, somewhat limited by existing regulations. The research work implemented this article is to study strength and stiffness cases where steel reinforcement tensile zone composite polymer compressive concrete. Concrete beams with combined obje...

Ground vibration is one of the undesirable results of blasting operations. Different methods have been proposed to predict and control ground vibration that is caused by blasting. These methods can be classified as laboratory studies, fieldwork and numerical modeling. Among these methods, numerical modeling is the one which saves time and cuts costs since it takes into account the basic princip...
