Numerical Study on Concrete Pumping Behavior via Local

To better understand the fresh concrete pumping mechanisms in detail, the discrete element method is employed in this paper for the numerical simulation of local pumping problems. By modeling the coarse aggregates as rigid clumps and appropriately defining the contact models, the concrete flow in representative pipeline units is well revealed.

Numerical Study of the Behavior of Reinforced Concrete

A simple method based on the well-known sectional analysis approach is presented to trace the structural behavior of reinforced concrete (RC) shear walls exposed to fire. It is similar to the approaches described in the existing literature but it does not require computations of moment-curvature curve group. This method can take into account material nonlinearity by use of the coupling
