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.
Ram concept mat foundation tutorial.
Alternative metric values and units are identified in square brackets next to the us units.
Ram concept is a program analysis and design using finite element methods for high concrete floor system or the foundation system.
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.
Transfer floor or raft mat foundation geometry and loading including lateral load effects from ram structural system.
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.
Export reactions including post tensioning effects to ram structural system for column design.
The estimated perimeter of the mat must be modeled to encompass all of the supported columns and walls and some concrete deck also needs to be assigned to the mat in ram modeler.
The metric values are not exact conversions.
To design the foundations.
Mat foundation tutorial this chapter will walk you through the steps for modeling a mat foundation also known as a raft.
