![]() ![]() This analysis can be calculated in common MSE wall software programs such as the National Concrete Masonry Association’s SRWall 4.0 and MSEW 3.0, which was developed by Adama Engineering, Inc. The results of the study determined that secondary geogrid reinforcement reduces the load on the primary geogrid layers and the MSE wall face. ![]() PODCAST: Composite Materials Are Changing the Conversation in Geosynthetics SECONDARY GEOGRID REINFORCEMENT DESIGN APPROACHĪ research study was conducted at the University of Kansas and sponsored by the Kansas DOT. The reason is that MSE walls units which feature mechanical connections are generally designed to have sufficient connection capacity such that the geogrid design strength governs and not the connection capacity. ![]() Secondary reinforcement has generally not been used for MSE walls that rely upon a mechanical connection between geogrid reinforcement and MSE facing units. In these cases, the secondary layers do not connect to the facing. Secondary geogrid has also been used where it is placed behind larger MSE wall facing, such as with PCM units, gabion wire baskets, and rockery boulders.
