Frame Model

RAM Frame analyzes the model created in the RAM Modeler. Typically the model can contain both gravity and frame members and gravity loads distribution can be carried out according to one-way or two-way load distribution. The program provides data for all of the gravity and lateral members plus deck information, slab edges and surface loads. Referring to systems with one-way slabs, tributary floor load, reactions from gravity beams and live load reduction factors are determined and applied to the lateral members. Diaphragm mass properties are calculated for each diaphragm at stories. Also for systems with two-way slabs, gravity loads can be directly applied to slabs, which allow engineers to include two-way load distribution for gravity loads. These model types take advantage of the integrated capabilities of the RAM Structural System The engineer could also choose to create a model that consists only of lateral (frame) members, without modeling the gravity beams and columns, slabs, slab edges, etc., in which case only point and line loads applied directly to the frame members are considered in the analysis.
