Study the Effect of Transient Load on Pipeline Supported by Concrete Blocks

A three dimensional analysis of dynamic load - nonlinear soil - concrete blocks - pipeline have been investigated to study the major factors that influencing the response of whole system and which dominate on the interaction between different component of the problem. The present work consider the effect of pipe diameter, distance between applied force and whole system, distance between concrete blocks or span of pipe. Aspects which addressed in this study the effect of the previous factors on deformation which can be express as vertical displacement and bending moment , friction stresses between concrete blocks and soil and Also the behavior of concrete blocks with time and distance. ABAQUS software is used to reveal the effect of these factors on structural behavior of whole system.
