Mat foundation tutorial this chapter will walk you through the steps for modeling a mat foundation also known as a raft.
Ram concept mat foundation tutorial.
The metric values are not exact conversions.
The system can be floor or the concrete after tensioning pt reinforced concrete rc or hybrid a mixture between pt and rc.
Ram concept automatically multiples the area spring constant units of force per cubic length by the tributary area of each finite node determined from mesh size to determine the spring constant units of force per length at each node.
Mat foundations modeled in ram structural system can be exported into ram concept for analysis and design using the ram manager design ram concept option or from within ram concept using file sync ram structural system new from ram ss.
Alternative metric values and units are identified in square brackets next to the us units.
Transfer floor or raft mat foundation geometry and loading including lateral load effects from ram structural system.
The foundations should now appear yellow indicating that the foundations are all ready to be designed with the exception of the mat foundation which can only be designed using ram concept.
The program will calculate the optimum sizes for all of the footings.
Select process design all footings.
Export reactions including post tensioning effects to ram structural system for column design.
