In the early 20th century prominent Russian scientists—Professors I. G. Maliuga, N. A. Zhitkevich, S. I. Druzhinin, and N. K. Lakhtin—worked on questions of the technology of concrete, of concrete and reinforced-concrete operations, and of the design of structures using reinforced concrete. Original designs proposed by the engineers N. M. Abramov and A. F. Loleit appeared. The Volkhov

Reinforced concrete - Wikipedia

Reinforced concrete (RC), also called reinforced cement concrete (RCC), is a composite material in which concrete''s relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars and is usually eedded passively in the concrete before the concrete

Measured Load Capacity of Buried Reinforced Concrete Pipes

fies two methods for the design of reinforced concrete pipe: Indirect Design and Direct Design. The Indirect Design Method attempts to relate the critical load obtained during three-edge bearing tests conducted by the pipe manufac-turer (ASTM C497-13) to the capacity of the pipes in-place through a modifiion factor known as the bedding factor. The critical load is specified as the load at

Even with three different universities establishing a n value of 0.010, the concrete pipe industry steadfastly maintains that a safety factor must be applied to the laboratory values for design to account for increased friction due to grade and angle changes, inlets, manholes, bed loads, and other factors that could affect flow characteristics. Therefore, the following values are recommended

Recommendations for Design of Reinforced Concrete Pipe

The direct design method permits more accurate design of pipe and evaluation of pipe structural behavior using design procedures that are similar to those used for other reinforced concrete structures. The soil-structure interaction analysis is based on a finite-element pipe-soil model which allows calculation of both loads acting on the pipe and the moments, thrusts, and shears at points in
