Simplified Micro-Modeling of Partially-Grouted Reinforced Masonry Shear Walls of Hollow Concrete Blocks

A 2D finite element based simplified micro-modeling approach is employed to simulate the lateral in-plane lateral response of partially-grouted reinforced concrete shear walls made of hollow concrete blocks. The modeling methodology is employed to reproduce the experimental results of full-scale tests of shear walls, which have two different layouts of horizontal reinforcement: embedded in bed-joints or embedded in the blocks. The mechanical properties required for models were mostly experimentally measured. Results indicate good agreement in the maximum bearing capacity as well as the failure model.
