![]() ![]() The following limitations comply with the requirements of Concrete Masonry Association of Australia Manual MA53 "Segmental Concrete. The NCMA manual adopts an overall approach that is similar to recommendations found in the FHW A and AASHTO guidelines but that extends and refines the methods of analysis and design to consider explicitly all performance aspects of dry-stacked segmental retaining wall units. The 90-minute presentation is based on NCMA's recently released Segmental Retaining Wall Best Practices Guide. the design of a retaining wall or reinforced slope consists of the following principal activities: develop wall/slope geometry provide adequate subsurface investigation evaluate loads and pressures that will act on the structure design the structure to withstand the loads and pressures design the structure to meet aesthetic 4.Unit weight of soils is assumed to be 120 pcf. ![]() Design Software for Segmental Retaining Walls, SRWall 4.0.
