Reinforced Concrete Analysis
Currently, many structural engineers do not take masonry (or more technically infill walls) into account when they design a structure. In other words, they assume that the masonry that goes in between the structure has no effect on the building. The problem with this approach is during an earthquake, the bricks can affect the fundamental manner in which the structure reacts because, contrary to the design philosophy, they carry load and increase the stiffness of the building. My research is based on using a computer simulation called OpenSees to discover the effect of masonry walls on a building during an earthquake and trying to figure out how they affect the structures performance during a variety of different earthquakes. The goal of this is to determine whether we need to change the structural design philosophy, or whether the deficiencies of the philosophy are marginal and will have a small impact in the long run.
