Experimental and Finite Element Simulation of D-Load Test and Significance of Crack Width for Concrete Pipes

Complete three-dimensional finite element (FEM) model of the "D-Load" test conducted on the reinforced concrete (RC) pipes is simulated by using three-dimensional FEM method. The simulation will predict the test up to failure by scaled dynamic analysis and discrete crack model. The crack model uses the constitutive material law for concrete coupled with tension stiffening algorithm. Also, the failure modes observed for different pipe diameters are documented and reported. To verify the FEM algorithm, the three-edge bearing tests known as "D-Load" tests are conducted on eight full-scale reinforced concrete pipes with 18-in. (0.46-m), 36-in. (0.91-m), and 54-in. (1.37-m) diameters manufactured per the ASTM C76-08. The experimental tests closely exhibited the FEM results both when comparing load-deformation and crack initiation and propagation. Further, the crack width was measured and its significance in pipe stiffness characteristics is discussed.
